Significant accounting policies [Abstract]
Significant accounting policies	Note 2. Significant accounting policies These unaudited interim consolidated financial statements for the periods ended 31 December 2022 have been prepared in accordance with IAS 34 Interim Financial Reporting d for a complete s The principal accounting policies adopted are consistent with those of the previous financial year and corresponding interim reporting period, unless otherwise stated. New or amended Accounting Standards and Interpretations adopted The Group has adopted all of the new or amended IFRS and Interpretations as issued by the International Accounting Standards Board ('IASB') that are mandatory for the current reporting period. Any new or amended Accounting Standards or Interpretations that are not yet mandatory have not been early adopted. The Group believes that the impact of recently issued standards or amendments to existing standards that are not yet effective will not have a material impact on the Group's unaudited interim consolidated financial statements. Going concern The Group has determined there is material uncertainty that may cast significant doubt on the Group’s ability to continue as a going concern but has concluded it is appropriate to prepare the consolidated financial statements on a going concern basis which contemplates continuity of normal business activities, the realization of assets and settlement of liabilities in the ordinary course of business. The operating cashflows generated by the Group are inherently linked to several key uncertainties and risks including, but not limited to, volatility associated with the economics of Bitcoin mining and the ability of the Group to execute its business plan. As further background, the Group’s miners are designed specifically to mine Bitcoin and its future success will depend in a large part upon the value of Bitcoin, and any sustained decline in Bitcoin’s value could adversely affect the business and results of operations. Specifically, the revenues from Bitcoin mining operations are predominantly based upon two factors: (i) the number of Bitcoin rewards that are successfully mined and (ii) the value of Bitcoin. A continued decline in the market price of Bitcoin, an increase in the difficulty of Bitcoin mining, changes in the regulatory environment and/or adverse changes in other inherent risks would significantly negatively impact the Group’s operations. Due to the volatility of the Bitcoin price and the effects of possible changes in the other aforementioned factors, there can be no guarantee that future mining operations will be profitable. The strategy to mitigate these risks and uncertainties is to execute a business plan aimed at continued reliability, operational efficiency, revenue growth, improving overall mining profit, managing operating expenses and working capital requirements, maintaining capital expenditure optionality, and securing additional financing, as needed, through one or more debt and/or equity capital raisings. The Group can wind down its operations (including not acquiring any additional mining hardware and/or incurring the associated infrastructure growth capital expenditure) in the event of unfavourable pricing in Bitcoin. The continuing viability of the Group and its ability to continue as a going concern and meet its debts and commitments as they fall due are therefore significantly dependent upon several factors. These factors have been considered in preparing a cash flow forecast over the next 12 months to consider the going concern of the Group. The key considerations in developing these assumptions include: ● A base case scenario assuming current Bitcoin prices and global hashrate for the next 12 months, which has been considered at various bitcoin and hashrate scenarios; ● The completion of key construction projects including energization of 20MW at Childress, Texas and receipt of associated construction and energization deposit refunds prior to 30 June 2023; ● The Group does not currently have any corporate level debt outstanding. On 4 November 2022, IE CA 3 Holdings Ltd. and IE CA 4 Holdings Ltd. (‘Non-Recourse SPVs’) received notices of defaults from the lenders under their respective limited recourse facilities alleging the occurrence of certain defaults and potential events of default, and purporting to declare the loans under each of the Non-Recourse SPV facilities immediately due and payable. The lender to the Non-Recourse SPVs is taking steps to enforce the indebtedness and its rights in the collateral securing such limited recourse facilities (including the approximately 3.6 EH/s of miners securing such facilities and other assets of such Non-Recourse SPVs), and appointed a receiver to the Non-Recourse SPVs on February 3, 2023. See note 12 for further information; and ● The Group entered into an agreement with B. Riley Principal Capital II, LLC (“B. Riley”) effective 26 January 2023 pursuant to which Iris Energy Limited has the option, but not the obligation, to sell up to $100 million of ordinary shares to B. Riley over the next two years. For the purposes of the going concern assessment, the Group has assumed utilization of this facility in line with the terms of the agreement. These key assumptions have been considered using a range of historic Bitcoin price and global hashrate scenarios. The Group aims to maintain a degree of flexibility in both operating and capital expenditure cashflow management where it practicably makes sense, including ongoing internal cashflow monitoring and projection analysis performed to identify potential liquidity risks arising and to be able to respond accordingly. For the six-month period ended 31 December 2022, the Group incurred a loss after tax of $161,894,000 (31 December 2021: $418,767,000) and net operating cash outflows of $6,263,000 (31 December 2021 inflows of $11,377,000). As at 31 December 2022, the Group had net current liabilities of $65,589,000 (30 June 2022 net current assets: $75,148,000) and net assets of $270,123,000 (30 June 2022: $437,362,000). Net current assets excluding current borrowings held by the Non-Recourse SPVs as at 31 December 2022 is $45,001,000. As a result, the Group has concluded there is material uncertainty related to events or conditions that may cast significant doubt on the Group’s ability to continue as a going concern and, therefore, that it may be unable to realize its assets and discharge its liabilities in the normal course of business. However, the Group considers that it will be successful in the above matters and will have adequate cash reserves to enable it to meet its obligations for at least one year from the date of approval of the consolidated financial statements, and, accordingly, has prepared the consolidated financial statements on a going concern basis. Foreign operations The assets and liabilities of foreign operations are translated into US dollars using the relevant exchange rates at the reporting date. The revenues and expenses of foreign operations are translated into US dollars using the average exchange rates, which approximate the rates at the dates of the transactions, for the period. All resulting foreign exchange differences are recognized in other comprehensive income/(loss) through the foreign currency translation reserve in equity. The foreign currency translation reserve is recognized in profit or loss when the foreign operation or net investment is disposed of.

The growth rate does not exceed the long-term average growth rate for the business. The Group has applied a pre-tax discount rate of 19.5% to discount the forecast future cash flows attributable to the CGU. In forecasting cash flows over the three-year period, management has assumed a Bitcoin price and global hashrate based on historic data, completion of key construction sites within the Group, and electricity costs remain within the current regulated levels in British Columbia, Canada and at forecasted external market pricing in unregulated markets. As at 31 December 2022, management determined that the Group’s carrying value was not supported by its recoverable amount. Based on the associated VIU projections, the Group impaired its goodwill of $603,000 to $ nil Given the VIU did not support the carrying amount of the CGU, management also estimated the fair value less cost of disposal of the assets in the CGU. This was performed using the market approach, based on observable market prices for similar assets. As a result, an impairment of $25,700,000 was recognized on the Group’s mining hardware. The analysis supported the carrying value of the Group’s infrastructure assets (Land, Buildings, Plant and equipment). As the mining hardware assets held by the Non-Recourse SPVs are no longer expected to generate future cashflows for the Group, their associated carrying value was excluded from the Group’s CGU impairment testing. A separate impairment charge of $46,000,000 has been recognized to reduce the carrying value of the Non-Recourse SPV’s assets to their expected net realizable value to the Group (i.e. equal to the value of the third-party debt outstanding in each of the Non-Recourse SPVs) (see note 12 for further information). The impairment expense described above has been recognized in the unaudited interim consolidated statements of profit or loss as impairment of assets.

The CRA has issued an assessment in relation to one of the entities which, the Directors believe would be applied across the Group’s Canadian subsidiaries. Under the proposed decision, the CRA has noted that ITCs claimed by the Group would be allowed. However, the Canadian subsidiaries would also be required to remit an amount of 5% on services exported to the Australian parent under an intercompany service agreement. The export of services typically attract a 0% rate of GST in Canada. If GST were to apply to these services at a rate of 5%, the Australian parent may not be permitted to recover this tax. The Group has submitted additional information to the CRA to further support the ITCs claimed and the 0% rate applied to the exported services and submitted a formal notice of objection to the CRA in November 2022. The CRA has acknowledged receipt of the appeal application however has not yet provided any further correspondence to the Group. As at 31 December 2022, the above provision includes $1,215,000 recorded in the Non-Recourse SPVs. Other The other provision balance of $1,258,000 relates to cash and cash equivalents held by the Non-Recourse SPVs and not expected to be recoverable by the Group. The related expense for this provision has been recognized in profit or loss as impairment of assets.

Share-based payments [Abstract]
Share-based payments	Note 18. S hare-bas The Group has entered into a number of share-based compensation arrangements. Details of these arrangements, which are considered as options for accounting purposes, are described below: Employee Share Plan The Group's Employee Share Plan is a loan-funded share scheme. These loan-funded shares generally vest subject to satisfying employment service periods (and in some cases, non-market-based performance milestones). The employment service periods are generally met in three equal tranches on the third, fourth and fifth anniversary of the grant date. Under this scheme, the Company issues a limited recourse loan (that has a maximum term of up to 9 years and 11 months The recourse on the loan is limited to the lower of the initial amount of the loan granted to the employee and the proceeds from the sale of the underlying shares. Employees are entitled to exercise the voting and dividend rights attached to the shares from the date of allocation. If the employee leaves the Company within the vesting period, the shares may be bought back by the Company at the original issue price and the loan is repaid. Loan-funded shares have been treated as options as required under IFRS 2 Share-based Payments. Vesting of instruments granted under the Employee Share Plan is dependent on specific service thresholds being met by the employee. 2021 Executive Director Liquidity and Price Target Options On 20 January 2021, the Group's board approved the grant of 1,000,000 options each to entities controlled by Daniel Roberts and William Roberts (each an Executive Director) to acquire ordinary shares at an exercise price of $3.8647 (A$5.0005) with an expiration date of 20 December 2025 ● If the IPO price or volume weighted average market price (‘VWAP’) of an ordinary share over any consecutive 20 trading day period is equal to or exceeds $5.41 (A$7.00): 300,000 options vest ● If the IPO price or VWAP of an ordinary share over any consecutive 20 trading day period is equal to or exceeds $6.96 (A$9.00): 300,000 options vest ● If the IPO price or VWAP of an ordinary share over any consecutive 20 trading day period is equal to or exceeds $8.50 (A$11.00): 400,000 options vest The option holder is entitled to receive, in its capacity as a holder of the options, an income distribution per vested option equal to any dividend, distribution, capital return or buyback proceeds (collectively, ‘Distribution’) paid by the Company per ordinary share as if any vested options were exercised and ordinary shares issued to the option holder at the relevant time of such Distribution. The options are subject to customary adjustments to reflect any reorganization of the Company’s capital. As at 31 December 2022, none of the 2,000,000 outstanding vested 'Executive Director Liquidity and Price Target Options' have been exercised. Employee Option Plan The Board approved an Employee Option Plan on 28 July 2021. The terms of the Employee Option Plan are substantially similar to the Employee Share Plan, with the main difference being that the incentives are issued in the form of options and loans are not provided to participants. If the employee leaves the Company within the vesting period of the options granted, the Board retains the absolute discretion to cancel any unvested options held by the employee. Vesting of options granted under the Employee Option Plan is dependent on specific service thresholds being met by the employee. Non-Executive Director Option Plan The Board approved a Non-Executive Director Option Plan (‘NED Option Plan’) on 28 July 2021. The terms of the NED Option Plan are substantially similar to the Employee Option Plan. Vesting of instruments granted under the NED Option Plan is dependent on specific service thresholds being met by the Non-Executive Director. Where an option holder ceases to be a Director of the Company within the vesting period, the options granted to that Director will vest on a pro-rata basis of the associated service period. The Board retains the absolute discretion to cancel any remaining unvested options held by the option holder. 2021 Executive Director Long-term Target Options On 18 August 2021, the Group's shareholders approved the grant of 2,400,000 long-term options each to entities controlled by Daniel Roberts and William Roberts to acquire ordinary shares at an exercise price of $75 per option (‘Long-term Target Options’). These options were granted on 14 September 2021, and have a contractual exercise period of 12 years. The Long-term Target Options will vest in four tranches following listing of the Company, if the relevant ordinary share price is equal to or exceeds the corresponding vesting threshold and the relevant Executive Director has not voluntarily resigned as a Director of the Company. The vesting thresholds are detailed below: ● If the VWAP of an ordinary share over the immediately preceding 20 trading days is equal to or exceeds $370: 600,000 Long-term Target Options will vest. ● If the VWAP of an ordinary share over the immediately preceding 20 trading days is equal to or exceeds $650: 600,000 Long-term Target Options will vest. ● If the VWAP of an ordinary share over the immediately preceding 20 trading days is equal to or exceeds $925: 600,000 Long-term Target Options will vest. ● If the VWAP of an ordinary share over the immediately preceding 20 trading days is equal to or exceeds $1,850: 600,000 Long-term Target Options will vest. The VWAP vesting thresholds may also be triggered by a sale or takeover of the Company based upon the price per ordinary share received in such transaction. The option holder is entitled to receive in its capacity as a holder of the options, a distribution paid by the Company per ordinary share as if the vested options were exercised and ordinary shares issued to the option holder at the relevant time of such distribution. The options are subject to customary adjustments to reflect any reorganization of the Company's capital, as well as adjustments to vesting thresholds including any future issuance of ordinary shares by the Company. Restricted Share Units ('RSUs') On 1 July 2022, the Group issued a total of 1,953,535 restricted share units. These RSUs include a grant of 1,073,706 RSUs to the below Directors of the Company: Director Title Number of RSU's granted Daniel Roberts Executive Director and Co-CEO 534,853 William Roberts Executive Director and Co-CEO 534,853 Michael Alfred Non-Executive Director 4,000 229,223 of the RSUs each granted to Daniel Roberts and William Roberts have associated vesting conditions of which 50% of each individual's RSU grant will vest after 3.25 years and the remaining 50% will vest after 4.25 years, subject to the following criteria which is tested at the end of each respective vesting period: - 80% vesting based on continued service with the Group over the vesting period; and - 20% vesting based on total shareholder return against a peer group of Nasdaq listed entities (and continued service over the vesting period). 305,630 of the RSUs granted to each of Daniel Roberts and William Roberts are subject to a sole vesting condition and will immediately vest when the daily closing share price of the of the ordinary shares of Company exceeds $28 for 10 trading days out of any 15 consecutive full trading day period following the grant date. The 4,000 RSUs issued to Michael Alfred vested on 15 December 2022 as he met the sole service condition of remaining as a Non-executive Director of the Company until 15 December 2022. 325,415 RSUs were also granted to the below executive Key Management Personnel (‘KMP’) and Company Secretary with the remaining 554,414 RSU’s issued to other executives and employees of the Group.

On 16 December 2022, the Group issued a total of 104,559 restricted share units to Non-Executive Directors of the Company. These RSUs will vest at the earlier of within 10 days of the release of the consolidated Group financial statements for the year ended 30 June 2023 or by 31 December 2023: Director Title Number of RSU's granted David Batholomew Non-Executive Director 34,853 Chris Guzowski Non-Executive Director 34,853 Michael Alfred Non-Executive Director 34,853 For all RSUs issued the Board has full discretion to, at any time, interpret, apply or not apply, amend, modify, or terminate the LTIP, any plan rules and any individual RSU granting and vesting.

Events after the reporting period	Note 20. Events after the reporting period Committed Equity Facility Iris Energy Limited entered into an agreement with B. Riley Principal Capital II, LLC (“B. Riley”) effective 26 January 2023 pursuant to which Iris Energy has the option, but not the obligation, to sell up to $100 million of ordinary shares to B. Riley over the next two years. The facility has not yet been utilized. Bitmain prepayments and mining hardware sales In early January 2023, the Group further utilized mining hardware prepa yments December equal to the net cash proceeds received in January On 8 February 2023, the Group entered into an agreement to utilize all remaining prepayments of US$66.7 (1) million under its 10 EH/s contract with Bitmain, which includes a concurrent sale of 2.3 EH/s of the remaining 6.7 EH/s contracted miners to a third party, to acquire 4.4 EH/s of new miners without any additional cash outlay. Newly acquired miners are to be installed in the Company’s data centers, increasing self-mining operating capacity to 5.5 EH/s over the coming months. The Group is considering options for the sale of surplus miners to re-invest in growth initiatives and/or corporate purposes. Following this transaction, the Group’s obligations under its existing 10 EH/s contract with Bitmain (as disclosed in Note 17) have been fully resolved, with no remaining commitments. Appointment of receiver to Non-Recourse SPVs On January 20, 2023, the lender filed a petition with the British Columbia Supreme Court, primarily seeking the appointment of PwC as receiver over the assets and undertakings of the Non-Recourse SPVs, in relation to their failures to make payments when due under their respective equipment financing agreements. The court subsequently appointed PwC as the receiver of the Non-Recourse SPVs on 3 February 2023. Update to key management personnel On 25 January 2023, the Group announced the retirement of its president, Lindsay Ward.

Significant accounting policies [Abstract]
Basis of preparation	These unaudited interim consolidated financial statements for the periods ended 31 December 2022 have been prepared in accordance with IAS 34 Interim Financial Reporting d for a complete s The principal accounting policies adopted are consistent with those of the previous financial year and corresponding interim reporting period, unless otherwise stated.
New or amended Accounting Standards and Interpretations adopted	New or amended Accounting Standards and Interpretations adopted The Group has adopted all of the new or amended IFRS and Interpretations as issued by the International Accounting Standards Board ('IASB') that are mandatory for the current reporting period. Any new or amended Accounting Standards or Interpretations that are not yet mandatory have not been early adopted. The Group believes that the impact of recently issued standards or amendments to existing standards that are not yet effective will not have a material impact on the Group's unaudited interim consolidated financial statements.
Going concern	Going concern The Group has determined there is material uncertainty that may cast significant doubt on the Group’s ability to continue as a going concern but has concluded it is appropriate to prepare the consolidated financial statements on a going concern basis which contemplates continuity of normal business activities, the realization of assets and settlement of liabilities in the ordinary course of business. The operating cashflows generated by the Group are inherently linked to several key uncertainties and risks including, but not limited to, volatility associated with the economics of Bitcoin mining and the ability of the Group to execute its business plan. As further background, the Group’s miners are designed specifically to mine Bitcoin and its future success will depend in a large part upon the value of Bitcoin, and any sustained decline in Bitcoin’s value could adversely affect the business and results of operations. Specifically, the revenues from Bitcoin mining operations are predominantly based upon two factors: (i) the number of Bitcoin rewards that are successfully mined and (ii) the value of Bitcoin. A continued decline in the market price of Bitcoin, an increase in the difficulty of Bitcoin mining, changes in the regulatory environment and/or adverse changes in other inherent risks would significantly negatively impact the Group’s operations. Due to the volatility of the Bitcoin price and the effects of possible changes in the other aforementioned factors, there can be no guarantee that future mining operations will be profitable. The strategy to mitigate these risks and uncertainties is to execute a business plan aimed at continued reliability, operational efficiency, revenue growth, improving overall mining profit, managing operating expenses and working capital requirements, maintaining capital expenditure optionality, and securing additional financing, as needed, through one or more debt and/or equity capital raisings. The Group can wind down its operations (including not acquiring any additional mining hardware and/or incurring the associated infrastructure growth capital expenditure) in the event of unfavourable pricing in Bitcoin. The continuing viability of the Group and its ability to continue as a going concern and meet its debts and commitments as they fall due are therefore significantly dependent upon several factors. These factors have been considered in preparing a cash flow forecast over the next 12 months to consider the going concern of the Group. The key considerations in developing these assumptions include: ● A base case scenario assuming current Bitcoin prices and global hashrate for the next 12 months, which has been considered at various bitcoin and hashrate scenarios; ● The completion of key construction projects including energization of 20MW at Childress, Texas and receipt of associated construction and energization deposit refunds prior to 30 June 2023; ● The Group does not currently have any corporate level debt outstanding. On 4 November 2022, IE CA 3 Holdings Ltd. and IE CA 4 Holdings Ltd. (‘Non-Recourse SPVs’) received notices of defaults from the lenders under their respective limited recourse facilities alleging the occurrence of certain defaults and potential events of default, and purporting to declare the loans under each of the Non-Recourse SPV facilities immediately due and payable. The lender to the Non-Recourse SPVs is taking steps to enforce the indebtedness and its rights in the collateral securing such limited recourse facilities (including the approximately 3.6 EH/s of miners securing such facilities and other assets of such Non-Recourse SPVs), and appointed a receiver to the Non-Recourse SPVs on February 3, 2023. See note 12 for further information; and ● The Group entered into an agreement with B. Riley Principal Capital II, LLC (“B. Riley”) effective 26 January 2023 pursuant to which Iris Energy Limited has the option, but not the obligation, to sell up to $100 million of ordinary shares to B. Riley over the next two years. For the purposes of the going concern assessment, the Group has assumed utilization of this facility in line with the terms of the agreement. These key assumptions have been considered using a range of historic Bitcoin price and global hashrate scenarios. The Group aims to maintain a degree of flexibility in both operating and capital expenditure cashflow management where it practicably makes sense, including ongoing internal cashflow monitoring and projection analysis performed to identify potential liquidity risks arising and to be able to respond accordingly. For the six-month period ended 31 December 2022, the Group incurred a loss after tax of $161,894,000 (31 December 2021: $418,767,000) and net operating cash outflows of $6,263,000 (31 December 2021 inflows of $11,377,000). As at 31 December 2022, the Group had net current liabilities of $65,589,000 (30 June 2022 net current assets: $75,148,000) and net assets of $270,123,000 (30 June 2022: $437,362,000). Net current assets excluding current borrowings held by the Non-Recourse SPVs as at 31 December 2022 is $45,001,000. As a result, the Group has concluded there is material uncertainty related to events or conditions that may cast significant doubt on the Group’s ability to continue as a going concern and, therefore, that it may be unable to realize its assets and discharge its liabilities in the normal course of business. However, the Group considers that it will be successful in the above matters and will have adequate cash reserves to enable it to meet its obligations for at least one year from the date of approval of the consolidated financial statements, and, accordingly, has prepared the consolidated financial statements on a going concern basis.
Foreign operations	Foreign operations The assets and liabilities of foreign operations are translated into US dollars using the relevant exchange rates at the reporting date. The revenues and expenses of foreign operations are translated into US dollars using the average exchange rates, which approximate the rates at the dates of the transactions, for the period. All resulting foreign exchange differences are recognized in other comprehensive income/(loss) through the foreign currency translation reserve in equity. The foreign currency translation reserve is recognized in profit or loss when the foreign operation or net investment is disposed of.
