Description of Business, Basis of Presentation [Abstract]
Description of Business, Basis of Presentation	1. Description of Business, Basis of Presentation (a) Description of the Business Coronado Global Resources Inc. (together with its subsidiaries, the “Company” or “Coronado”) is a global producer, marketer, and exporter of a full range of metallurgical coals, an essential element in the production of steel. The Company has a portfolio of operating mines and development projects in Queensland, Australia and in the states of Pennsylvania, Virginia and West Virginia in the USA. (b) Basis of Presentation The interim unaudited condensed consolidated financial statements have been prepared in accordance with the requirements of the U.S. Generally Accepted Accounting Principles, or U.S. GAAP, and with the instructions to Form 10-Q and Article 10 of Regulation S-X related to interim financial reporting issued by the Securities and Exchange Commission, or the SEC. Accordingly, they do not include all of the information and footnotes required by U.S. GAAP for complete financial statements and should be read in conjunction with the audited consolidated financial statements and notes thereto included in the Company’s Annual Report on Form 10-K filed with the SEC and the Australian Securities Exchange, or the ASX, on February 24, 2020. The interim unaudited condensed consolidated financial statements are presented in U.S. dollars, unless otherwise stated. They include the accounts of Coronado Global Resources Inc. and its affiliates. References to “US$” or “USD” are references to U.S. dollars. References to “A$” or “AUD” are references to Australian dollars, the lawful currency of the Commonwealth of Australia. The Company, or Coronado, are used interchangeably to refer to Coronado Global Resources Inc. and its subsidiaries, or to Coronado Global Resources Inc., as appropriate to the context. Interests in subsidiaries controlled by the Company are consolidated with any outside stockholder interests reflected as noncontrolling interests. All intercompany balances and transactions have been eliminated in consolidation. In the opinion of management, these interim financial statements reflect all normal, recurring adjustments necessary for the fair presentation of the Company’s financial position, results of operations, comprehensive income, cash flows and changes in equity for the periods presented. Balance sheet information presented herein as of December 31, 2019 has been derived from the Company’s audited consolidated balance sheet at that date. The Company’s results of operations for the three and six months ended June 30, 2020 are not necessarily indicative of the results that may be expected for future quarters or for the year ending December 31, 2020. COVID-19 The COVID-19 global pandemic has continued to result in a challenging working environment which has significantly impacted the demand and price for metallurgical coal. Authorities in many countries around the world have implemented numerous and varying measures to reduce the spread and limit the impact of COVID-19, including travel bans and restrictions, quarantines, curfews, stay-at-home orders, business shutdowns and closures. Many countries have also commenced implementing multi-stage policies with the goal of re-opening markets and boosting economic activity. These measures have impacted and will continue to impact our mining operations, our customers, employees, suppliers and other third parties with whom we do business. The U.S. and Australia, where our mining operations are located, are in varying stages of restrictions and re-opening in response to COVID-19. There is considerable uncertainty regarding how current and future health and safety measures implemented in response to the pandemic will impact our business, including whether they will result in further changes in demand for metallurgical coal, increases in operating costs or impacts to our supply chain, and whether measures will result in port closures or border restrictions, each or all of which can impact our ability to produce and sell our coal. The safety and wellbeing of our workforce remains our highest priority and we continue to manage the potential threat of COVID-19 at our mines and offices. The Company formed a COVID-19 taskforce spanning its Australian and U.S. operations and proactively enacted stringent preventative measures to ensure the safety and well-being of employees and contractors during the pandemic. These procedures include increased screenings of employees as they arrive at the workplace as well as strict adherence to hygiene and social distancing guidelines while at work. Our U.S. Operations were idled in April and May 2020 due to the COVID-19 induced economic downturn and decline in demand from customers in Europe, Brazil and the U.S. While the mines were idled, the Company continued to make shipments to its customers from existing inventories which allowed the Company to meet all customer commitments. On June 1, 2020, the Company resumed operations at the Buchanan and Logan mines. Whilst production at these mines has been reduced in response to lower temporary demand, both mines are operationally well positioned to increase production quickly in the event demand increases rapidly. The Greenbrier mine remains idle and the Company will continue to monitor market developments to evaluate the duration for which the mine will remain idle. Subsequent to June 30, 2020 we have had a small number of our workforce at our U.S Operations who tested positive for the virus. We have taken all necessary steps to isolate the affected workers and protect the remaining workforce. To date these efforts have not adversely affected our production. The global economic slowdown resulting from the effects of COVID-19 has sharply reduced the demand for steel in all markets except for China, where steel production remained elevated during the second quarter of 2020. In Australia, our sales profile has adjusted accordingly, with an increase in deliveries to the Chinese market in the quarter. Overall, the supply and demand constraints in respect of the global impacts of COVID-19 on our Australian Operations has been limited due to the unique position of the Curragh mine as a strategic supplier of ‘base load’ metallurgical coal for coke blends. While global demand remains uncertain, there are promising signs of recovery in Asia Pacific demand. In response to the global impacts of COVID-19 on the demand for steel and the resulting impact on the price and demand for metallurgical coal, the Company has taken steps to safeguard its operations, strengthen its balance sheet and increase liquidity by reducing capital expenditures and managing operating costs in a disciplined manner. As of June 30, 2020, the Company reduced its net debt by $ 31.8 million to $ 404.9 million since March 31, 2020, and had $ 109.0 million undrawn and available under the Syndicated Facility Agreement, or SFA, subject to a liquidity buffer of $ 50.0 million, and cash balances (excluding restricted cash) of $ 36.1 million. See Note 13 “Interest Bearing Liabilities”. As the COVID-19 pandemic continues to evolve, the Company cannot currently predict the extent of this pandemic, which could have a material adverse impact to its business, results of operations, financial condition and ability to comply with financial covenants under the SFA.

Summary of Significant Accounting Policies [Abstract]
Summary of Significant Accounting Policies	2. Summary of Significant Accounting Policies Please see Note 2 “Summary of Significant Accounting Policies” contained in the audited consolidated financial statements for the year ended December 31, 2019 included in Coronado Global Resources Inc.’s Annual Report on Form 10-K filed with the SEC and ASX on February 24, 2020. (a) Newly Adopted Accounting Standards Financial Instruments - Credit Losses. In June 2016, the FASB issued ASU 2016-13 related to the measurement of credit losses on financial instruments. The pronouncement replaces the incurred loss methodology to record credit losses with a methodology that reflects the expected credit losses for financial assets not accounted for at fair value with gains and losses recognized through net income. On January 1, 2020, the Company adopted ASU 2016-13. The cumulative-effect adjustment upon adoption was not material to the Company’s results of operations and its cash flows. Changes to the Company’s accounting policies as a result of adoption are discussed below. The Company assesses on a forward-looking basis the expected credit loss associated with its financial assets carried at amortized cost. The amount of expected credit losses is updated at each reporting date to reflect changes in credit risk since initial recognition of the respective financial instrument. The Company recognizes the lifetime expected credit losses for financial assets carried at amortized cost. The expected credit losses on these financial assets are estimated based on the Company’s historic credit loss experience, adjusted for factors that are specific to the financial asset, general economic conditions, financial asset type, term and an assessment of both the current as well as forecast conditions at the reporting date. Fair Value Measurement . In August 2018, the FASB issued ASU 2018-13, which amended the fair value measurement guidance by removing and modifying certain disclosure requirements, while also adding new disclosure requirements. On January 1, 2020, the Company adopted ASU 2018-13. The amendments on changes in unrealized gains and losses, the range and weighted average of significant unobservable inputs used to develop Level 3 fair value measurements and the narrative description of measurement uncertainty were applied prospectively for only the most recent interim period presented. All other amendments were applied retrospectively to all periods presented. The adoption of ASU 2018-13 did not have a material impact on the Company’s unaudited condensed consolidated financial statements. Intangibles – Goodwill and Other: Simplifying the Test for Goodwill Impairment . In January 2018, the FASB issued ASU 2017-04, which eliminates step two from the goodwill impairment test. Under ASU 2017-04, an entity should recognize an impairment charge for the amount by which the carrying amount of a reporting unit exceeds its fair value up to the amount of goodwill allocated to that reporting unit. On January 1, 2020, the Company adopted ASU 2017-04. Changes to the Company’s accounting policies as a result of adoption are discussed below. Goodwill is an asset representing the future economic benefits arising from other assets acquired in a business combination that are not individually identified and separately recognized. Goodwill is not amortized but is reviewed for impairment annually or when circumstances or other events indicate that impairment may have occurred. The Company makes a qualitative assessment of whether it is more likely than not that a reporting unit’s fair value is less than its carrying amount. Circumstances that are considered as part of the qualitative assessment and could trigger a quantitative impairment test include but are not limited to: a significant adverse change in the business climate; a significant adverse legal judgment; adverse cash flow trends; an adverse action or assessment by a government agency; unanticipated competition; and a significant restructuring charge within a reporting unit. If a quantitative assessment is determined to be necessary, the Company compares the fair value of a reporting unit with its carrying amount, including goodwill. If the carrying amount of a reporting unit exceeds its fair value, the Company recognizes an impairment charge for the amount by which the carrying amount exceeds its fair value to the extent of the amount of goodwill allocated to that reporting unit. The Company defines reporting units at the business unit level. For purposes of testing goodwill for impairment, goodwill has been allocated to the reporting units to the extent it relates to each reporting unit. (b) Accounting Standards Not Yet Implemented “Income Taxes - Simplifying the Accounting for Income Taxes” - In December 2019, the FASB issued ASU 2019-12, which is intended to simplify various aspects related to accounting for income taxes. ASU 2019-12 removes certain exceptions to the general principles in Topic 740 and clarifies and amends existing guidance to improve consistent application. ASU 2019-12 will be effective for interim and annual periods beginning after December 15, 2020. The Company is currently evaluating the impact the adoption of ASU 2019-12 will have on its consolidated financial statements. (c) Reclassification Certain amounts in the prior period Condensed Consolidated Balance Sheet have been reclassified to conform to the presentation of the current period financial statements. These related to the reclassification of four reportable segments into the current two reportable segments discussed in Note 3 “Segment information”. These reclassifications had no effect on the previously reported net income.

Segment Information [Abstract]
Segment Information	3. Segment Information The Company has a portfolio of operating mines and development projects in Queensland, Australia and in the states of Pennsylvania, Virginia and West Virginia in the USA. The Company operates four coal mine complexes: Curragh, Buchanan, Logan and Greenbrier. Commencing on January 1, 2020, the Company updated its reportable segments to be the country in which they operate, that is Australia and the United States, in order to align with the manner in which its Chief Operating Decision Maker, or CODM, views the Company’s business for purposes of reviewing performance and allocating resources. Factors affecting and differentiating the financial performance of each of these two reporting segments generally include coal quality, geology, and coal marketing opportunities, mining and transportation methods and regulatory issues. This is the basis on which internal financial and operational reports are currently prepared and provided to the CODM and reflects how the CODM manages performance and determines the allocation of resources within the Company. The Company believes this method of segment reporting reflects both the way its business segments are currently managed and the way the performance of each segment is evaluated. Comparative disclosures have been restated to a consistent basis. The CODM uses Adjusted EBITDA as the primary metric to measure each segment’s operating performance. Adjusted EBITDA is not a measure of financial performance in accordance with U.S. GAAP. Investors should be aware that the Company’s presentation of Adjusted EBITDA may not be comparable to similarly titled financial measures used by other companies. Adjusted EBITDA is defined as earnings before interest, tax, depreciation, depletion and amortization and other foreign exchange losses. Adjusted EBITDA is also adjusted for certain discrete items that management exclude in analyzing each of our segments’ operating performance. “Other and corporate” relates to additional financial information for the corporate function such as accounting, treasury, legal, human resources, compliance, and tax. As such, the corporate function is not determined to be a reportable segment but is discretely disclosed for purposes of reconciliation to the Company’s consolidated financials. Reportable segment results as of and for the three and six months ended June 30, 2020 and 2019 are presented below: Australia United States Other and Corporate Total ($ thousands) Three months ended June 30, 2020 Total revenues 228,410 75,938 — 304,348 Adjusted EBITDA ( 6,804) 3,490 ( 7,163) ( 10,477) Net loss ( 16,933) ( 74,006) ( 23,391) ( 114,330) Total assets 1,043,222 975,045 83,042 2,101,309 Capital expenditures (1) 13,535 6,396 578 20,509 Three months ended June 30, 2019 Total revenues 412,810 229,647 — 642,457 Adjusted EBITDA 151,561 79,642 ( 8,912) 222,291 Net income (loss) 91,024 40,609 ( 14,127) 117,506 Total assets 1,182,652 972,193 63,638 2,218,483 Capital expenditures (1) 9,341 27,426 — 36,767 Six Months Ended June 30, 2020 Total revenues 473,555 240,111 — 713,666 Adjusted EBITDA 6,260 41,740 ( 13,056) 34,944 Net loss ( 22,900) ( 64,877) ( 35,419) ( 123,196) Total assets 1,043,222 975,045 83,042 2,101,309 Capital expenditures (1) 18,804 41,917 1,206 61,927 Six Months Ended June 30, 2019 Total revenues 794,182 440,153 — 1,234,335 Adjusted EBITDA 271,709 151,611 ( 17,965) 405,355 Net income (loss) 159,758 77,409 ( 22,841) 214,326 Total assets 1,182,652 972,193 63,638 2,218,483 Capital expenditures (1) 15,431 50,996 3 66,430 (1) Capital expenditures includes financing fees incurred through other financial liabilities for the purchase of certain equipment.

Impairment of Assets

Impairment of Assets [Abstract]
Impairment of Assets	4. Impairment of assets Long-lived assets, such as property, plant, and equipment, and purchased intangible assets subject to amortization, are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. If circumstances require a long-lived asset or asset group be tested for possible impairment, the Company first compares undiscounted pre-tax cash flows expected to be generated by that asset or asset group to its carrying value. If the carrying value of the long-lived asset or asset group is not recoverable on an undiscounted pre-tax cash flow basis, an impairment is recognized to the extent that the carrying value exceeds its fair value. Fair value is determined through various valuation techniques including discounted cash flow models, quoted market values and third-party independent appraisals, as considered necessary. No impairment losses were recognized for property, plant and equipment or amortizing intangible assets for the years ended December 31, 2019 and 2018. The following costs are reflected in “Impairment of Assets” in the unaudited Consolidated Statement of Operations and Other Comprehensive income for the three and six months ended June 30, 2020: Reportable Segment (US$ thousands) United States Property, plant and equipment, net $ 62,481 Right of use asset – operating leases, net 10 Intangible assets, net 620 Total $ 63,111 The Company generally does not view short-term declines in metallurgical coal prices in the markets in which it sells its products as a singular indicator of impairment. However, due to the decline in metallurgical coal prices during the six months ended June 30, 2020, the resulting impact on business conditions from COVID-19 and the idling of the Greenbrier mine for an undetermined period, there were indications that the carrying value of the Greenbrier mining asset, in the U.S., exceeded its fair value. The Company performed an impairment assessment in accordance with the rules of ASC 360 – Property, Plant and Equipment, and determined an impairment charge of $ 63.1 million reducing the carrying value of Greenbrier’s long-lived assets to approximately $ 50.0 million as at June 30, 2020. The fair value of the Greenbrier mining asset was derived using Level 3 inputs and was primarily driven by estimates of future cash flows based on a combination of historical results adjusted to reflect the Company’s best estimate of future market and operating conditions, including its current life of mine plan, and reserve multiple valuation. The Company concluded that no indicators of impairment or requisite charges were required at any of the Company’s other mining assets as at June 30, 2020.

Trade and Related Party Receivables [Abstract]
Trade and Related Party Receivables	6. Trade and related party receivables The Company extends trade credit to its customers in the ordinary course of business. Trade receivables and related party receivables are recorded initially at fair value and subsequently at amortized cost, less any Expected Credit Losses, or ECL. Trade receivables from provisionally priced sales are carried at fair value to profit or loss. For trade and related party receivables carried at amortized cost, the Company determines ECL on a forward-looking basis. The amount or ECL is updated at each reporting date to reflect changes in credit risk since initial recognition of the respective financial instrument. The Company recognizes the lifetime ECL. The ECL is estimated based on the Company’s historic credit loss experience, adjusted for factors that are specific to the financial asset, general economic conditions, financial asset type, term and an assessment of both the current as well as forecast conditions at the reporting date, modified for credit enhancements such as letters of credit obtained. To measure ECL, trade and related party receivables have been grouped based on shared credit risk characteristics and the days past due. The Company considers an event of default has occurred when a financial asset is significantly past due or other factors indicate that the debtor is unlikely to pay amounts owed to the Company. A financial asset is credit impaired when there is evidence that the counterparty is in significant financial difficulty or a breach of contract, such as default or past due event has occurred. The Company writes off a financial asset when there is information indicating there is no realistic prospect of recovery of the asset from the counterparty. The amount of the impairment loss is recognized in the consolidated statement of operations and other comprehensive income within “other, net”. Subsequent recoveries of amounts previously written off are credit against “other, net” in the consolidated statement of operations and other comprehensive income.

The Company has not recognised any bad debt expense from trading counterparties in the three and six months ended June 30, 2020 and 2019. Related party receivables - Xcoal During the three and six months ended June 30, 2020, the Company sold coal to Xcoal Energy and Resources, or Xcoal, an entity associated with Non-Executive director, Mr. Ernie Thrasher. Revenues from Xcoal of $ 9.0 million and $ 135.3 million, respectively, are recorded as “Coal revenues from related parties” in the unaudited Condensed Consolidated Statement of Operations and Comprehensive Income for the three months ended June 30, 2020 and 2019. Revenues from Xcoal of $ 89.1 million and $ 293.2 million, respectively, are recorded as coal revenues in the unaudited Condensed Consolidated Statement of Operations and Comprehensive Income for the six months ended June 30, 2020 and 2019. During the three and six months ended June 30, 2020, the Company purchased coal from Xcoal totalling $ 7.9 million and the corresponding payable was offset against trade receivables from Xcoal. The cost of purchasing coal from Xcoal is recorded within “Cost of coal revenues” in the Unaudited Condensed Consolidated Statement of Operations and Comprehensive Income. At June 30, 2020, amounts due from Xcoal in respect of coal sales were $ 105.1 million. At December 31, 2019, amounts due from Xcoal in respect of coal sales were $ 86.8 million.

Leases [Abstract]
Leases	11. Leases From time to time, the Company enters into mining services contracts which may include embedded leases of mining equipment and other contractual agreements to lease mining equipment and facilities. Based upon the Company’s assessment of the terms of a specific lease agreement, the Company classifies a lease as either finance or operating. On March 31, 2020, the Company amended one of its mining service contracts for mining equipment assets used to provide mining services. On execution of the amendment, right of use assets of $ 25.9 million and lease liabilities of $ 27.0 million were derecognized. These mining equipment assets were previously deemed leased assets embedded within the mining service contract.

Income Taxes [Abstract]
Income Taxes	12. Income Taxes For the six months ended June 30, 2020 and 2019, the Company estimated its annual effective tax rate and applied this effective tax rate to its year-to-date pretax income at the end of the interim reporting period. The tax effect of unusual or infrequently occurring items, including effects of changes in tax laws or rates and changes in judgment about the realizability of deferred tax assets, are reported in the interim period in which they occur. The Company’s 2020 estimated annual effective tax rate, including discrete items, is 14.2%. The Company had an income tax benefit of $ 20.4 million for the six months ended June 30, 2020, comprising a discrete income tax expense of $ 1.0 million and income tax benefit of $ 21.4 million based on a loss before tax of $ 143.6 million. Income tax expense of $ 89.0 million for the six months ended June 30, 2019 was calculated based on an estimated annual effective tax rate of 29.4% for the period. The Company utilizes the “more likely than not” standard in recognizing a tax benefit in its financial statements. For the six months ended June 30, 2020 and the year ended December 31, 2019, the Company had $ 14.2 million of unrecognized tax benefits. If accrual for interest or penalties is required, it is the Company’s policy to include these as a component of income tax expense. The Company is subject to taxation in the United States and its various states, as well as Australia and its various localities. In the United States and Australia, the first tax return was lodged for the year ended December 31, 2018 . On March 27, 2020, the United States Congress enacted the Coronavirus Aid, Relief and Economic Security Act, or CARES Act, to provide certain relief as a result of the COVID-19 outbreak. The CARES Act (PL 116-136), allows for a five-year carryback for losses arising in tax years beginning in 2018, 2019 and 2020. As there was U.S. taxable income in tax years 2018 and 2019, there is an opportunity to carryback the 2020 losses in order to receive a refund of taxes assessed in these tax years of approximately $ 16.7 million. By virtue of carrying back net operating losses, there will be no longer an opportunity to utilize foreign tax credits in these tax years.

Interest Bearing Liabilities [Abstract]
Interest Bearing Liabilities	13. Interest Bearing Liabilities The Company’s SFA, comprises of Facility A ($ 350 million loan facility), Facility B (A$ 130 million bank guarantee facility) and Facility C ($ 200 million loan facility). The SFA has a termination date of February 15, 2023. The SFA is a revolving credit facility under which the Company may borrow funds from Facility A and/or Facility C for a period of one , two , three or six months , each referred to as a Term. The interest rate is set at the commencement of each Term. At the end of each Term, the Company may elect to repay the loan or extend any loan amount outstanding for a further period of one two three six months Due to the global impacts of COVID-19 on the demand and pricing for metallurgical coal and the resulting uncertainties associated with the pandemic, on May 25, 2020, the Company entered into an agreement with its lenders in the SFA to waive compliance with certain financial covenants for the period from May 25, 2020 to February 28, 2021, or the waiver period. A breach of these financial covenants at the end of, or after, the waiver period will constitute an event of default under the SFA and all amounts outstanding at that point may become due and payable. The terms of the SFA will revert to the originally agreed terms at the end of the waiver period. As at June 30, 2020 the Company met its financial covenants and other undertakings under the SFA. The Company is pursuing a number of strategic initiatives to strengthen its liquidity and is actively engaged with its Lenders in relation to the extension of the waiver, referred to above, beyond February 28, 2021. These steps are expected to ensure the continuing availability of the SFA beyond February 28, 2021. During the six months ended June 30, 2020, the Company borrowed a total amount of $ 145.0 million under the SFA for working capital and corporate purposes. Repayments of $ 34.0 million were made during the six months ended June 30, 2020. The total interest bearing liabilities outstanding under the SFA was $ 441.0 million and $ 330.0 million as at June 30, 2020 and December 31, 2019, respectively.

Deferred Consideration Liability [Abstract]
Deferred Consideration Liability	15. Deferred Consideration Liability On August 14, 2018 the Company completed the purchase of the Stanwell Reserved Area, or the SRA, adjacent to the current Curragh mining tenements. This area was acquired on a deferred consideration basis and on acquisition the Company recognized a “Right-to-mine-asset” and a corresponding deferred consideration liability of $ 155.2 million, calculated using a pre-tax discount rate of 13% representing fair value of the arrangements at the date of acquisition. The deferred consideration liability will reflect passage of time changes by way of an annual accretion at the pre-tax discount rate of 13% while the liability will decrease as domestic coal is supplied to Stanwell from the SRA. The accretion of deferred consideration is recognized in “Interest expense, net” in the unaudited Condensed Consolidated Statements of Operations and Comprehensive Income.

Derivatives And Fair Value Measurement [Absract]
Derivatives and Fair Value Measurement	17. Derivatives and Fair Value Measurement (a) Derivatives The Company may use derivative financial instruments to manage its financial risks in the normal course of operations, including foreign currency risks, commodity price risk related to purchase of raw materials (such as gas or diesel) and interest rate risk. Derivatives for speculative purposes are strictly prohibited under the Treasury Risk Management Policy approved by the Board of Directors. The financing counterparties to the derivative contracts potentially expose the Company to credit-related risk. Credit risk is the risk that a third party might fail to fulfill its performance obligations under the terms of the financial instrument. The Company mitigates credit risk by entering into derivative contracts with high credit quality counterparties, limiting the amount of exposure to each counterparty and frequently monitoring their financial condition. Forward fuel contracts In 2019, the Company entered into forward derivative contracts to hedge its exposure to diesel fuel that is used, or expects to use, at its operations in Australia, or Australian Operations, during 2020. During the six month period ended June 30, 2020, the Company entered into additional derivative contracts in relation to diesel fuel that it expects to consume at its Australian Operations during 2021. The aggregate notional amount for all outstanding forward diesel fuel derivative contracts designated as cash flow hedges were $ 82.2 million at June 30, 2020. Unrealized losses, net of tax, recognized in “Accumulated other comprehensive income/(loss)” as at June 30, 2020, are expected to be recognized into “Cost of coal revenues” in the Unaudited Condensed Statements of Operations and Comprehensive Income, $ 16.0 million within the next 12 months and $ 4.1 million within 6 months thereafter, when the hedged transaction impacts income. Refer to Note 18 “Other comprehensive loss” for further disclosure. Forward foreign currency contracts The Australian Operations utilize the cash it generates from its US$ denominated coal sales revenue to fund its operating costs, which are predominantly in A$. The Company enters into forward foreign currency contracts to hedge its foreign exchange exposure on a portion of the US$ denominated coal sales revenue at Curragh, whose functional currency is A$. The aggregated notional amount of the outstanding forward foreign currency derivative contracts designated as cash flow hedges were $ 57.5 million as at June 30, 2020. The unrealized loss of $ 0.1 million, net of tax, recognized in “Accumulated other comprehensive income/(loss)” at June 30, 2020, is expected to be recognized into “Coal revenues” in the Unaudited Condensed Statements of Operations and Comprehensive Income within the next 6 months, when the hedged transaction impacts income. Refer to Note 18 “Other comprehensive loss” for further disclosure. During the six month period ended June 30, 2020, the Company entered into additional forward foreign currency derivative contracts to manage its exposure to US$ at the Australian Operations. The aggregate notional amount for the outstanding forward foreign currency derivative contracts was $ 55.1 million at June 30, 2020. The unrealized gain of $ 1.4 million, net of tax, was recognized in “Other, net” in the Unaudited Condensed Statements of Operations and Comprehensive Income. The fair value of foreign currency and diesel fuel derivatives reflected in the accompanying unaudited Condensed Consolidated Balance Sheet are set forth in the table below: June 30, 2020 December 31, 2019 (US$ thousands) Classification Derivative asset Derivative liability Derivative asset Derivative liability Forward fuel contracts Other current assets — — 3,180 — Other current liabilities — 15,991 — — Other non-current liabilities — 4,106 — — Forward foreign currency contracts Other current assets 1,510 — 953 — Other current liabilities — 54 — — 1,510 20,151 4,133 — The following table presents our details of foreign currency and diesel fuel outstanding contracts: June 30, 2020 December 31, 2019 (in thousands) Notional amount (thousands) Unit of measure Varying maturity dates Notional amount (thousands) Unit of measure Varying maturity dates Forward fuel contracts 199,636 Liters July 2020 - December 2021 121,957 Liters January 2020 – December 2020 Forward foreign currency contracts 112,632 US$ July 2020 - December 2020 24,300 US$ January 2020 – March 2020 Fair Value of Financial Instruments The fair value of a financial instrument is the amount that will be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. The fair values of financial instruments involve uncertainty and cannot be determined with precision. The Company utilizes valuation techniques that maximize the use of observable inputs and minimize the use of unobservable inputs to the extent possible. The Company determines fair value based on assumptions that market participants would use in pricing an asset or liability in the market. When considering market participant assumptions in fair value measurements, the following fair value hierarchy distinguishes between observable and unobservable inputs, which are categorized in one of the following levels: Level 1 Inputs: Unadjusted quoted prices in active markets for identical assets or liabilities accessible to the reporting entity at the measurement date. Level 2 Inputs: Other than quoted prices that are observable for the asset or liability, either directly or indirectly, for substantially the full term of the asset or liability. Level 3 Inputs: Unobservable inputs for the asset or liability used to measure fair value to the extent that observable inputs are not available, thereby allowing for situations in which there is little, if any, market activity for the asset or liability at measurement date. Financial Instruments Measured on a Recurring Basis As of June 30, 2020, the Company has the following liabilities that are required to be measured at fair value on a recurring basis:  Forward commodity contracts: valued based on a valuation that is corroborated by the use of market-based pricing (Level 2)  Foreign currency forward contracts: valued based on a valuation that is corroborated by the use of market-based pricing (Level 2)  Contingent royalty: fair value is determined using the Black-Scholes option pricing formula (Level 3) The following tables set forth the hierarchy of the Company’s net financial liabilities positions for which fair value is measured on a recurring basis as of June 30, 2020: Assets/(Liabilities) (US$ thousands) Level 1 Level 2 Level 3 Total Forward commodity contracts $ — $ ( 20,097) $ — $ ( 20,097) Forward foreign currency contracts — 1,456 — 1,456 $ — $ ( 18,641) $ — $ ( 18,641) The Company’s net financial liability positions for which fair value is measured on a recurring basis as of December 31, 2019 was as follows: Assets/(Liabilities) (US$ thousands) Level 1 Level 2 Level 3 Total Forward commodity contracts $ — $ 3,180 $ — $ 3,180 Forward foreign currency contracts — 953 — 953 Contingent royalty — — ( 1,543) ( 1,543) $ — $ 4,133 $ ( 1,543) $ 2,590 Contingent Royalty Consideration Key assumptions in the valuation include the gross sales price forecast, export volume forecast, volatility, the risk-free rate, and credit-spread of the Company. Quantitative Information about Level 3 Fair Value Measurements (US$ thousands) Fair value at June 30, 2020 Valuation technique Unobservable input Range (Weighted Avg.) Contingent Royalty Liability $ — Projected cash flows Gross sales price forecast per ton $ 67.1 to $ 105.2 ($ 81.7) Export volume forecast (000’s) 1,816 tons over 9 months Given the remaining period of the Contingent Royalty obligation is short-term, the valuation technique has been changed from Black-Scholes Option model to projected cash flows. As a result of the decline in market coal price and the increase of the agreed floor price as the agreement reaches maturity, the Company's projected cash flows resulted in no Contingent royalty liability as at June 30, 2020. Value Share Mechanism As part of the acquisition of Curragh on March 29, 2018, the Company agreed to pay a 25% royalty to the seller on sales from metallurgical coal mined at Curragh over a two-year no VSM payments during the six months period ended June 30, 2020. Other Financial Instruments The following methods and assumptions are used to estimate the fair value of other financial instruments as of June 30, 2020 and December 31, 2019:  Cash and restricted cash, accounts receivable, accounts payable, accrued expenses, lease liabilities and other current financial liabilities: The carrying amounts reported in the unaudited Condensed Consolidated Balance Sheets approximate fair value due to the short maturity of these instruments.  Deposits and reclamation bonds, lease liabilities, interest bearing liabilities and other financial liabilities: The fair values approximate the carrying values reported in the unaudited Condensed Consolidated Balance Sheets.

(b) Other commitments As of June 30, 2020, purchase commitments for capital expenditures were $ 25.9 million, all of which is obligated within the next 12 months. In Australia, the Company has generally secured the ability to transport coal through rail contracts and coal export terminal contracts that are primarily funded through take-or-pay arrangements with terms ranging up to 11 years. In the U.S., the Company typically negotiates its rail and coal terminal access on an annual basis. As of June 30, 2020, these Australian and U.S. commitments under take-or-pay arrangements totaled $ 1.5 billion, of which approximately $ 101.2 million is obligated within the next year.

Contingencies [Abstract]
Contingencies	20. Contingencies In the normal course of business, the Company is a party to certain guarantees and financial instruments with off-balance sheet risk, such as letters of credit and performance or surety bonds. No liabilities related to these arrangements are reflected in the Company’s unaudited Condensed Consolidated Balance Sheets. Management does not expect any material losses to result from these guarantees or off-balance sheet financial instruments. Facility B of the SFA provides A$ 130 million for issuing multicurrency bank guarantees. At June 30, 2020, Facility B of the SFA had been utilized to issue A$ 68.9 million of bank guarantees on behalf of the Company. For the U.S. Operations in order to provide the required financial assurance, the Company generally uses surety bonds for post-mining reclamation and workers’ compensation obligations. The Company can also use bank letters of credit to collateralize certain obligations. As of June 30, 2020, the Company had outstanding surety bonds of $ 40.0 million, to secure various obligations and commitments. Curragh is a co-appellant to proceedings in the Queensland Supreme Court brought by Aurizon. Aurizon’s claim relates to costs relating to the co-defendants’ use of the Wiggins Island Coal Export Terminal Pty Ltd, or WICET, rail links, in particular, whether the “First Milestone Target Date”, which triggers certain “WIRP Fee” payments under the Wiggins Island Rail Project Deed, or WIRP Deed, has been achieved. The trial for this matter concluded in September 2018 and judgement was delivered by the Supreme Court in July 2019. Ultimately, Aurizon was successful in that trial and a determination was made that a WIRP Fee premium is payable by the defendants under the WIRP Deed. The defendants appealed the decision in the Queensland Court of Appeal and the appeal hearing was held in March 2020. Judgement has been reserved by the Court of Appeal and is not expected to be delivered before August 2020. Resolution of this dispute would also result in the Company’s below rail access to WICET (of 1.5 MMtpa) becoming a firm contractual capacity entitlement (and the subject of a 20 year take-or-pay access agreement) instead of an ad hoc entitlement only. The Company’s unaudited Condensed Consolidated Balance Sheet includes an estimated loss contingency associated with these proceedings of approximately $ 5.3 million as at June 30, 2020. Should the defendant’s appeal process be unsuccessful, the amount of the WIRP Fee may materially differ from our current estimation. From time to time, the Company becomes a party to other legal proceedings in the ordinary course of business in Australia, the U.S. and other countries where the Company does business. Based on current information, the Company believes that such other pending or threatened proceedings are likely to be resolved without a material adverse effect on its financial condition, results of operations or cash flows. The liabilities recorded in relation to the above litigation do not include estimated future costs associated with legal representation, which, in accordance with the Company’s policy, are expensed as incurred. In management’s opinion, the Company is not currently involved in any legal proceedings, which individually or in the aggregate could have a material effect on the financial condition, results of operations and/or liquidity of the Company.

Description of the Business	(a) Description of the Business Coronado Global Resources Inc. (together with its subsidiaries, the “Company” or “Coronado”) is a global producer, marketer, and exporter of a full range of metallurgical coals, an essential element in the production of steel. The Company has a portfolio of operating mines and development projects in Queensland, Australia and in the states of Pennsylvania, Virginia and West Virginia in the USA.
Basis of Presentation	(b) Basis of Presentation The interim unaudited condensed consolidated financial statements have been prepared in accordance with the requirements of the U.S. Generally Accepted Accounting Principles, or U.S. GAAP, and with the instructions to Form 10-Q and Article 10 of Regulation S-X related to interim financial reporting issued by the Securities and Exchange Commission, or the SEC. Accordingly, they do not include all of the information and footnotes required by U.S. GAAP for complete financial statements and should be read in conjunction with the audited consolidated financial statements and notes thereto included in the Company’s Annual Report on Form 10-K filed with the SEC and the Australian Securities Exchange, or the ASX, on February 24, 2020. The interim unaudited condensed consolidated financial statements are presented in U.S. dollars, unless otherwise stated. They include the accounts of Coronado Global Resources Inc. and its affiliates. References to “US$” or “USD” are references to U.S. dollars. References to “A$” or “AUD” are references to Australian dollars, the lawful currency of the Commonwealth of Australia. The Company, or Coronado, are used interchangeably to refer to Coronado Global Resources Inc. and its subsidiaries, or to Coronado Global Resources Inc., as appropriate to the context. Interests in subsidiaries controlled by the Company are consolidated with any outside stockholder interests reflected as noncontrolling interests. All intercompany balances and transactions have been eliminated in consolidation. In the opinion of management, these interim financial statements reflect all normal, recurring adjustments necessary for the fair presentation of the Company’s financial position, results of operations, comprehensive income, cash flows and changes in equity for the periods presented. Balance sheet information presented herein as of December 31, 2019 has been derived from the Company’s audited consolidated balance sheet at that date. The Company’s results of operations for the three and six months ended June 30, 2020 are not necessarily indicative of the results that may be expected for future quarters or for the year ending December 31, 2020.
COVID-19	COVID-19 The COVID-19 global pandemic has continued to result in a challenging working environment which has significantly impacted the demand and price for metallurgical coal. Authorities in many countries around the world have implemented numerous and varying measures to reduce the spread and limit the impact of COVID-19, including travel bans and restrictions, quarantines, curfews, stay-at-home orders, business shutdowns and closures. Many countries have also commenced implementing multi-stage policies with the goal of re-opening markets and boosting economic activity. These measures have impacted and will continue to impact our mining operations, our customers, employees, suppliers and other third parties with whom we do business. The U.S. and Australia, where our mining operations are located, are in varying stages of restrictions and re-opening in response to COVID-19. There is considerable uncertainty regarding how current and future health and safety measures implemented in response to the pandemic will impact our business, including whether they will result in further changes in demand for metallurgical coal, increases in operating costs or impacts to our supply chain, and whether measures will result in port closures or border restrictions, each or all of which can impact our ability to produce and sell our coal. The safety and wellbeing of our workforce remains our highest priority and we continue to manage the potential threat of COVID-19 at our mines and offices. The Company formed a COVID-19 taskforce spanning its Australian and U.S. operations and proactively enacted stringent preventative measures to ensure the safety and well-being of employees and contractors during the pandemic. These procedures include increased screenings of employees as they arrive at the workplace as well as strict adherence to hygiene and social distancing guidelines while at work. Our U.S. Operations were idled in April and May 2020 due to the COVID-19 induced economic downturn and decline in demand from customers in Europe, Brazil and the U.S. While the mines were idled, the Company continued to make shipments to its customers from existing inventories which allowed the Company to meet all customer commitments. On June 1, 2020, the Company resumed operations at the Buchanan and Logan mines. Whilst production at these mines has been reduced in response to lower temporary demand, both mines are operationally well positioned to increase production quickly in the event demand increases rapidly. The Greenbrier mine remains idle and the Company will continue to monitor market developments to evaluate the duration for which the mine will remain idle. Subsequent to June 30, 2020 we have had a small number of our workforce at our U.S Operations who tested positive for the virus. We have taken all necessary steps to isolate the affected workers and protect the remaining workforce. To date these efforts have not adversely affected our production. The global economic slowdown resulting from the effects of COVID-19 has sharply reduced the demand for steel in all markets except for China, where steel production remained elevated during the second quarter of 2020. In Australia, our sales profile has adjusted accordingly, with an increase in deliveries to the Chinese market in the quarter. Overall, the supply and demand constraints in respect of the global impacts of COVID-19 on our Australian Operations has been limited due to the unique position of the Curragh mine as a strategic supplier of ‘base load’ metallurgical coal for coke blends. While global demand remains uncertain, there are promising signs of recovery in Asia Pacific demand. In response to the global impacts of COVID-19 on the demand for steel and the resulting impact on the price and demand for metallurgical coal, the Company has taken steps to safeguard its operations, strengthen its balance sheet and increase liquidity by reducing capital expenditures and managing operating costs in a disciplined manner. As of June 30, 2020, the Company reduced its net debt by $ 31.8 million to $ 404.9 million since March 31, 2020, and had $ 109.0 million undrawn and available under the Syndicated Facility Agreement, or SFA, subject to a liquidity buffer of $ 50.0 million, and cash balances (excluding restricted cash) of $ 36.1 million. See Note 13 “Interest Bearing Liabilities”. As the COVID-19 pandemic continues to evolve, the Company cannot currently predict the extent of this pandemic, which could have a material adverse impact to its business, results of operations, financial condition and ability to comply with financial covenants under the SFA.

Summary of Significant Accounting Policies [Abstract]
Newly Adopted Accounting Standards	(a) Newly Adopted Accounting Standards Financial Instruments - Credit Losses. In June 2016, the FASB issued ASU 2016-13 related to the measurement of credit losses on financial instruments. The pronouncement replaces the incurred loss methodology to record credit losses with a methodology that reflects the expected credit losses for financial assets not accounted for at fair value with gains and losses recognized through net income. On January 1, 2020, the Company adopted ASU 2016-13. The cumulative-effect adjustment upon adoption was not material to the Company’s results of operations and its cash flows. Changes to the Company’s accounting policies as a result of adoption are discussed below. The Company assesses on a forward-looking basis the expected credit loss associated with its financial assets carried at amortized cost. The amount of expected credit losses is updated at each reporting date to reflect changes in credit risk since initial recognition of the respective financial instrument. The Company recognizes the lifetime expected credit losses for financial assets carried at amortized cost. The expected credit losses on these financial assets are estimated based on the Company’s historic credit loss experience, adjusted for factors that are specific to the financial asset, general economic conditions, financial asset type, term and an assessment of both the current as well as forecast conditions at the reporting date. Fair Value Measurement . In August 2018, the FASB issued ASU 2018-13, which amended the fair value measurement guidance by removing and modifying certain disclosure requirements, while also adding new disclosure requirements. On January 1, 2020, the Company adopted ASU 2018-13. The amendments on changes in unrealized gains and losses, the range and weighted average of significant unobservable inputs used to develop Level 3 fair value measurements and the narrative description of measurement uncertainty were applied prospectively for only the most recent interim period presented. All other amendments were applied retrospectively to all periods presented. The adoption of ASU 2018-13 did not have a material impact on the Company’s unaudited condensed consolidated financial statements. Intangibles – Goodwill and Other: Simplifying the Test for Goodwill Impairment . In January 2018, the FASB issued ASU 2017-04, which eliminates step two from the goodwill impairment test. Under ASU 2017-04, an entity should recognize an impairment charge for the amount by which the carrying amount of a reporting unit exceeds its fair value up to the amount of goodwill allocated to that reporting unit. On January 1, 2020, the Company adopted ASU 2017-04. Changes to the Company’s accounting policies as a result of adoption are discussed below. Goodwill is an asset representing the future economic benefits arising from other assets acquired in a business combination that are not individually identified and separately recognized. Goodwill is not amortized but is reviewed for impairment annually or when circumstances or other events indicate that impairment may have occurred. The Company makes a qualitative assessment of whether it is more likely than not that a reporting unit’s fair value is less than its carrying amount. Circumstances that are considered as part of the qualitative assessment and could trigger a quantitative impairment test include but are not limited to: a significant adverse change in the business climate; a significant adverse legal judgment; adverse cash flow trends; an adverse action or assessment by a government agency; unanticipated competition; and a significant restructuring charge within a reporting unit. If a quantitative assessment is determined to be necessary, the Company compares the fair value of a reporting unit with its carrying amount, including goodwill. If the carrying amount of a reporting unit exceeds its fair value, the Company recognizes an impairment charge for the amount by which the carrying amount exceeds its fair value to the extent of the amount of goodwill allocated to that reporting unit. The Company defines reporting units at the business unit level. For purposes of testing goodwill for impairment, goodwill has been allocated to the reporting units to the extent it relates to each reporting unit.
Accounting Standards Not Yet Implemented	(b) Accounting Standards Not Yet Implemented “Income Taxes - Simplifying the Accounting for Income Taxes” - In December 2019, the FASB issued ASU 2019-12, which is intended to simplify various aspects related to accounting for income taxes. ASU 2019-12 removes certain exceptions to the general principles in Topic 740 and clarifies and amends existing guidance to improve consistent application. ASU 2019-12 will be effective for interim and annual periods beginning after December 15, 2020. The Company is currently evaluating the impact the adoption of ASU 2019-12 will have on its consolidated financial statements.
Reclassification	(c) Reclassification Certain amounts in the prior period Condensed Consolidated Balance Sheet have been reclassified to conform to the presentation of the current period financial statements. These related to the reclassification of four reportable segments into the current two reportable segments discussed in Note 3 “Segment information”. These reclassifications had no effect on the previously reported net income.
