Organization, Consolidation and Presentation of Financial Statements [Abstract]
Organization, Basis of Presentation, and Summary of Significant Accounting Policies	Organization, Basis of Presentation, and Summary of Significant Accounting Policies Organization Malibu Boats, Inc. (together with its subsidiaries, the “Company” or "Malibu"), a Delaware corporation formed on November 1, 2013, is the sole managing member of Malibu Boats Holdings, LLC (the "LLC"). The Company operates and controls all of the LLC's business and affairs and, therefore, pursuant to Accounting Standards Codification (“ASC”) Topic 810, Consolidation , consolidates the financial results of the LLC and its subsidiaries, and records a non-controlling interest for the economic interest in the Company held by the non-controlling holders of units in the LLC ("LLC Units"). See Note 2. Malibu Boats Holdings, LLC was formed in 2006 with the acquisition by an investor group, including affiliates of Black Canyon Capital LLC, Horizon Holdings, LLC and then-current management. The LLC is engaged in the design, engineering, manufacturing and marketing of innovative, high-quality, performance sports boats that are sold through a world-wide network of independent dealers. On October 23, 2014, the Company acquired all the outstanding shares of Malibu Boats Pty. Ltd. (the "Licensee"), Malibu's Australian licensee manufacturer with exclusive distributions rights in Australia and New Zealand markets. As a result of the acquisition, the Company also consolidates the financial results of the Licensee. The Company reports its results of operations under two reportable segments called U.S. and Australia based on their respective manufacturing footprints. Each segment participates in the manufacturing, distribution, marketing and sale of performance sport boats. The U.S. operating segment primarily serves markets in North America, South America, Europe, and Asia while the Australia operating segment principally serves the Australian and New Zealand markets. Basis of Presentation The accompanying unaudited interim condensed consolidated financial statements of the Company have been prepared in accordance with U.S. generally accepted accounting principles ("GAAP") for interim condensed financial statements and with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all information and disclosures of results of operations, financial position and changes in cash flow in conformity with GAAP for complete financial statements. Such statements should be read in conjunction with the audited consolidated financial statements and notes thereto of Malibu Boats, Inc. and subsidiaries for the year ended June 30, 2015 included in the Company's Annual Report on Form 10-K. In the opinion of management, the accompanying unaudited interim condensed consolidated financial statements reflect all adjustments considered necessary to present fairly the Company’s financial position at September 30, 2015 and the results of its operations and the cash flows for the three month periods ended September 30, 2015 and September 30, 2014 . Operating results for the three months ended September 30, 2015 are not necessarily indicative of the results that may be expected for the full year ending June 30, 2016 . Certain reclassifications have been made to the prior period presentation to conform to the current period presentation. Units and shares are presented as whole numbers while all dollar amounts are presented in thousands, unless otherwise noted. Principles of Consolidation The accompanying unaudited condensed consolidated financial statements include the operations and accounts of the Company and all subsidiaries thereof. All intercompany balances and transactions have been eliminated upon consolidation. Immaterial Correction of an Error in Prior Periods During the first quarter of fiscal 2016, the Company identified an error related to an overstatement of the non-controlling interest held by LLC Unit holders in the LLC and a corresponding understatement in paid in capital attributable to the Company's proportional ownership interest in the LLC. In accordance with Financial Accounting Standards Board (the "FASB") ASC Topic 250, Accounting Changes and Error Corrections , the Company evaluated the materiality of the error from quantitative and qualitative perspectives, and concluded that the error was immaterial to the Company’s prior period interim and annual consolidated financial statements. Since the revision was not material to any prior period interim or annual consolidated financial statements, no amendments to previously filed interim or annual periodic reports are required. Consequently, the Company revised the historical consolidated financial information presented herein and will reflect the same revisions in its forthcoming fiscal 2016 Form 10-K. For the fiscal year ended June 30, 2015, the immaterial error correction resulted in a decrease in non-controlling interest of $11,688 and a corresponding increase for the same amount in additional paid in capital within stockholders' deficit on the unaudited condensed consolidated balance sheet and within the statement of stockholders' deficit. There was no change in total stockholders’ deficit for the fiscal year ended June 30, 2015. Recent Accounting Pronouncements In July 2015, the FASB issued Accounting Standards Update ("ASU") No. 2015-11, Simplifying the Measurement of Inventory . This ASU changes the measurement principle for inventories valued under the first-in, first-out ("FIFO") or weighted-average methods from the lower of cost or market to the lower of cost and net realizable value. Net realizable value is defined by the FASB as estimated selling prices in the ordinary course of business, less reasonably predictable costs of completion, disposal and transportation. This ASU does not change the measurement principles for inventories valued under the last-in, first-out ("LIFO") method. This amendment is effective for fiscal years beginning after December, 15, 2016, including interim periods within those fiscal years and should be applied prospectively with earlier application permitted as of the beginning of an interim or annual reporting period. The Company is currently evaluating the impact of adopting this ASC amendment, but does not expect it will have a material impact. In April 2015, the FASB issued ASU No. 2015-05, Intangibles-Goodwill and Other-Internal-Use Software (Subtopic 350-40): Customer’s Accounting for Fees Paid in a Cloud Computing Arrangement . This ASU amended the ASC to clarify guidance regarding cloud computing arrangements and if they would be accounted for as a license of internal-use software. If the arrangement does not contain a software license, it must be accounted for as a service contract. The amendment may be applied either retrospectively or prospectively and is effective for fiscal years, and the interim periods thereafter, beginning after December 15, 2015, with early adoption permitted. The Company is currently evaluating the impact of adopting this ASC amendment, but does not expect it will have a material impact. In April 2015, the FASB issued ASU 2015-03, Interest—Imputation of Interest , which intends to simplify the presentation of debt issuance costs. Under current U.S. GAAP, debt issuance costs are reported on the balance sheet as assets and amortized as interest expense. ASU 2015-03 requires that they be presented on the balance sheet as a direct deduction from the carrying amount of the related debt liability, which is similar to the presentation of debt discounts or premiums. The costs will continue to be amortized to interest expense using the effective interest method. ASU 2015-03 is effective for annual periods and interim periods within those annual periods beginning after December 15, 2015. Early adoption is permitted. The standard requires retrospective application. The Company is currently evaluating the impact of adopting this ASC amendment, but does not expect it will have a material impact. In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers (Topic 606), which specifies how and when to recognize revenue as well as providing informative, relevant disclosures. ASU 2014-09 will become effective for fiscal years beginning after December 15, 2017. We are currently evaluating the impact on our consolidated financial statements and related disclosures. There are no other new accounting pronouncements that are expected to have a significant impact on the Company's unaudited condensed consolidated financial statements and related disclosures.

Other than in connection with the issuance of Class A Common Stock in connection with an equity incentive program, the Company must contribute to the LLC net proceeds and property, if any, received by the Company with respect to the issuance of such additional shares of Class A Common Stock. The Company shall cause the LLC to issue a number of LLC Units equal to the number of shares of Class A Common Stock issued such that, at all times, the number of LLC Units held by the Company equals the number of outstanding shares of Class A Common Stock. During the three months ended September 30, 2015 , the LLC issued a total of 23,359 LLC Units to the Company in connection with the Company's issuance of Class A Common Stock to a non-employee director for his services, the exchange of LLC Units held by a non-controlling LLC Unit holder to Class A Common Stock and the issuance of Class A Common Stock for the vesting of awards granted under the Company’s Long-Term Incentive Plan.

Acquisition

Business Combinations [Abstract]
Acquisition	Acquisition On October 23, 2014, the Company acquired all of the outstanding shares of Malibu Boats Pty Ltd., the Company's exclusive licensee in Australia since 1995. The Licensee had the exclusive right to manufacture and distribute Malibu and Axis products and spare parts in Australia and New Zealand. The acquisition provides direct control of the Company's brand worldwide and provides it with a strong footprint for future growth internationally in Asia. The aggregate purchase price for the transaction was $16.1 million , consisting of $13.3 million in cash and $2.8 million in equity equal to 170,889 shares of the Company's Class A Common Stock based on a closing price of $17.11 per share. Under the share sale agreement, the number of shares issued was based on the average closing price of shares of the Class A Common Stock for the 20 days immediately prior to, but not including, the closing date of the acquisition. Of the consideration paid in stock, 71.43% is restricted from sale for a period of 2 years from the acquisition date. The Company funded a portion of the purchase price payable in cash with additional borrowings under its revolving credit facility. The Company accounted for the transaction in accordance with ASC 805, Business Combinations . The total consideration given to the former owner of the Licensee has been allocated to the assets acquired and liabilities assumed based on their estimated fair values as of the date of the acquisition utilizing the assistance of third party valuation specialists. The following table summarizes the purchase price allocation based on the fair values of the assets acquired and liabilities of the Licensee assumed at the acquisition date: Consideration: Cash consideration paid $ 13,305 Equity consideration paid 2,837 Fair value of total consideration transferred $ 16,142 Recognized amounts of identifiable assets acquired and (liabilities assumed), at fair value: Cash $ 1,642 Accounts receivable 878 Inventories 5,023 Other current assets 195 Net property, plant, and equipment 1,191 Identifiable intangible assets 4,558 Other assets 45 Current liabilities (3,908 ) Deferred tax liabilities (1,407 ) Other liabilities (34 ) Fair value of assets acquired and liabilities assumed 8,183 Goodwill 7,959 Total purchase price $ 16,142 The fair value estimates for the Company's identifiable intangible assets acquired as part of the acquisition are as follows: Estimates of Fair Value Useful Life (in years) Reacquired franchise rights $ 1,579 5 Dealer relationships 2,808 15 Non-compete agreement 61 10 Backlog 110 0.3 Total $ 4,558 The value allocated to inventories reflects the estimated fair value of the acquired inventory based on the expected sales price of the inventory, less an estimated cost to complete and a reasonable profit margin. The fair value of the identifiable intangible assets were determined based on the following approaches: Reacquired Franchise Rights - The reacquired franchise rights intangible asset represents the value assigned to the remainder of the contractual term of the Licensee's exclusive manufacturing and distributors agreement with the Company and was determined using the multi-period excess earnings method under the income approach. No gain or loss was recognized on the reacquisition of the Company's franchise rights. Dealer Relationships - The value associated with the Licensee's dealer relationships is attributed to its long standing dealer distribution network. The estimate of fair value assigned to this asset was determined using the income approach, which requires an estimate or forecast of the expected future cash flows from the dealer relationships through the application of the distributor method under the multi-period excess earnings approach. Non-compete - As part of the acquisition, the Licensee entered into a ten -year non-compete agreement with its former owner. The fair value of the non-compete agreement was determined using the with or without method under the income approach which discounted future cash flows attributable to unfavorable impact of the agreement had it not been in place. Backlog - Backlog relates to the value of orders not yet shipped by Licensee at the acquisition date, and the fair values were based on an excess earnings approach associated with those orders. Backlog related assets are being recognized commensurate with recognition of the revenue for the orders on which the backlog intangible assets were determined. The fair value of these intangible assets are being amortized using the straight-line method to general and administrative expenses over their estimated useful lives. Goodwill of $7,959 arising from the acquisition consists of expected synergies and cost savings as well as intangible assets that do not qualify for separate recognition, such as assembled workforce, and was allocated to the Company’s Australian operating segment. None of the goodwill is expected to be deductible for income tax purposes. Acquisition-related costs of $824 , all of which were recorded in fiscal 2015, were expensed by the Company in the periods prior to the acquisition of Malibu Boats Pty Ltd., in selling, general and administrative expenses in the audited consolidated statement of operations and comprehensive income (loss). Net sales of $4,770 and net income of $40 attributable to the Licensee are included in the unaudited condensed consolidated statements of operations and comprehensive income (loss) for the three months ended September 30, 2015 . Pro Forma Financial Information (unaudited): The following unaudited pro forma financial consolidated results of operations for the three months ended September 30, 2015 and 2014 assume that the acquisition of Licensee had occurred as of July 1, 2014. The unaudited pro forma financial information combines historical results of Malibu with adjustments for depreciation and amortization attributable to fair value estimates on acquired tangible and intangible assets and eliminations of intercompany sales and cost of sales for the respective periods. The unaudited pro forma financial information is presented for informational purposes only and is not indicative of the results of operations that would have been achieved if the acquisition had taken place at the beginning of fiscal 2014 or of the results that may occur in the future: Three Months Ended September 30, 2015 2014 Net sales $ 57,240 $ 51,784 Net income 3,980 2,504 Net income attributable to Malibu Boats, Inc. 3,558 1,459 Basic earnings per share 0.20 0.10 Diluted earnings per share 0.20 0.07

Product Warranties Disclosures [Abstract]
Product Warranties	Product Warranties Effective for model year 2016, the Company began providing a limited warranty for a period up to five years for both Malibu and Axis brand boats. For model years prior to 2016, the Company provided a limited warranty for a period of up to three years for its Malibu brand boats and two years for its Axis products. The Company’s standard warranties require the Company or its dealers to repair or replace defective products during such warranty period at no cost to the consumer. The Company estimates the costs that may be incurred under its basic limited warranty and records as a liability in the amount of such costs at the time the product revenue is recognized. Factors that affect the Company’s warranty liability include the number of units sold, historical and anticipated rates of warranty claims and cost per claim. The Company assesses the adequacy of its recorded warranty liabilities by brand on a quarterly basis and adjusts the amounts as necessary. The Company utilizes historical claims trends and analytical tools to assist in determining the appropriate warranty liability. Changes in the Company’s product warranty liability were as follows: As of September 30, 2015 As of June 30, 2015 Beginning balance $ 6,610 $ 6,164 Add: Additions to warranty provision 1,123 3,210 Additions for Australian acquisition — 308 Adjustments to preexisting warranties 96 (514 ) Less: Warranty claims paid (649 ) (2,558 ) Ending balance $ 7,180 $ 6,610

Debt Disclosure [Abstract]
Financing	Financing Outstanding debt consisted of the following: As of September 30, 2015 As of June 30, 2015 Term loan $ 77,000 $ 78,500 Less current maturities (7,000 ) (6,500 ) Long term debt less current maturities $ 70,000 $ 72,000 Long-Term Debt Amended and Restated Line of Credit and Term Loan. On April 2, 2015, Malibu Boats, LLC entered into a credit agreement with a syndicate of banks led by SunTrust Bank that included a revolving credit facility and term loan (the “Amended and Restated Credit Agreement”). The proceeds from the Amended and Restated Credit Agreement were used to repurchase the Company's Class A Common Stock and refinance amounts outstanding under the previously existing revolving credit facility with the same bank. The obligations of Malibu Boats LLC under the Amended and Restated Credit Agreement are currently guaranteed by its parent, Malibu Boats Holdings, LLC, and its subsidiary, Malibu Boats Domestic International Sales Corp. and Malibu Australian Acquisition Corp. Malibu Boats, Inc. is not a party to the Amended and Restated Credit Agreement. The lending arrangements are required to be guaranteed by the LLC and the present and future domestic subsidiaries of Malibu Boats, LLC and are secured by substantially all of the assets of the LLC, Malibu Boats, LLC and Malibu Domestic International Sales Corp., and those of any future domestic subsidiary pursuant to a security agreement. The revolving credit facility and term loan mature on April 2, 2020. The Amended and Restated Credit Agreement is comprised of a $25,000 revolving commitment, none of which was outstanding as of September 30, 2015 , and a $80,000 term loan, which is subject to quarterly installments of $1,500 per quarter until March 31, 2016, then $2,000 per quarter until March 31, 2019 and $2,500 per quarter thereafter. Borrowings under the Amended and Restated Credit Agreement bear interest at a rate equal to either, at the Borrower's option, (i) the highest of the prime rate, the Federal Funds Rate plus 0.5% , or one-month LIBOR plus 1% (the “Base Rate”) or (ii) LIBOR, in each case plus an applicable margin ranging from 1.00% to 1.75% with respect to Base Rate borrowings and 2.00% to 2.75% with respect to LIBOR borrowings. The applicable margin will be based upon the consolidated leverage ratio of the LLC and its subsidiaries calculated on a consolidated basis. The Borrower will also be required to pay a commitment fee for the unused portion of the revolving credit facility, which will range from 0.25% to 0.40% per annum, depending on the LLC’s and its subsidiaries’ consolidated leverage ratio. At September 30, 2015 , the Company had an aggregate total of $77,000 outstanding under the term loan. The weighted average interest rate on the term loan was 2.71% for the three month period ending September 30, 2015 . The Company also has a swingline line of credit from SunTrust Bank in the principal amount of up to $5,000 due on or before April 2, 2020. Any amounts drawn under the swingline line of credit reduce the capacity under the revolving credit facility. As of September 30, 2015 , the Company had no outstanding balance under the swingline facility. Under the Amended and Restated Credit Agreement, the Company has the ability to issue letters of credit up to $5,000 . This letter of credit availability may be reduced by borrowings under the revolving line of credit. The Company’s access to these letters of credit expires April 2, 2020 with the expiration of access to the revolving commitment. As of September 30, 2015 , the Company had issued letters of credit for $100 . The Amended and Restated Credit Agreement permits prepayment without any penalties. It also requires prepayments from the net cash proceeds received by the Borrower or any guarantors from certain asset sales and recovery events, subject to certain reinvestment rights, and from excess cash flow, subject to the terms and conditions of the Amended and Restated Credit Agreement. It contains certain customary representations and warranties, and notice requirements for the occurrence of specific events such as the occurrence of any event of default, or pending or threatened litigation. The Amended and Restated Credit Agreement requires compliance with certain financial covenants that the Company believes are usual for facilities and transactions of this type, including a minimum ratio of EBITDA to fixed charges and a maximum ratio of total debt to EBITDA. The Amended and Restated Credit Agreement also contains certain restrictive covenants, which, among other things, place limits on the LLC's activities and those of its subsidiaries, the incurrence of additional indebtedness and additional liens on property and limit the future payment of dividends or distributions. For example, the Amended and Restated Credit Agreement generally prohibits the LLC, Malibu Boats, LLC and Malibu Domestic International Sales Corp. from paying dividends or making distributions, including to Malibu Boats, Inc. The Amended and Restated Credit Agreement permits, however, distributions based on a member’s allocated taxable income, distributions to fund payments that are required under the tax receivable agreement, payments pursuant to stock option and other benefit plans up to $2,000 in any fiscal year, dividends and distributions within the loan parties and dividends payable solely in interests of classes of securities. In addition, the LLC may make dividends and distributions of up to $6,000 in any fiscal year, subject to compliance with other financial covenants. The credit agreement specifies permitted liens, permitted investments and permitted debt. Affirmative covenants governing the timing of monthly, quarterly and annual financial reporting are also included in the credit agreement. In connection with the Amended and Restated Credit Agreement, the Company capitalized $1,224 in deferred financing costs. These costs were classified as other assets, net and are being amortized over the term of the Amended and Restated Credit Agreement into interest expense using the effective interest method. Covenant Compliance As of September 30, 2015 , the Company is in full compliance with the terms of the Amended and Restated Credit Agreement, including all related covenants. Interest Rate Swap On July 1, 2015, the Company entered into a five year floating to fixed interest rate swap with an effective start date of July 1, 2015. The swap is based on a one-month LIBOR rate versus a 1.52% fixed rate on a notional value of $39,250 , which under terms of the Amended and Restated Credit Agreement is equal to 50% of the outstanding balance of the term loan at the time of the swap arrangement. Under ASC Topic 815, Derivatives and Hedging, all derivative instruments are recorded on the consolidated balance sheets at fair value as either short term or long term assets or liabilities based on their anticipated settlement date. Refer to Fair Value Measurements in Note 10. The Company has elected not to designate its interest rate swap as a hedge; therefore, changes in the fair value of the derivative instrument are being recognized in earnings in the Company's condensed consolidated statements of operations and comprehensive income (loss). During the quarter ended September 30, 2015 , the Company recorded a loss of $557 for the change in fair value of the interest rate swap, which is included in interest expense in the unaudited condensed consolidated statements of operations and comprehensive income (loss).

Tax Receivable Agreement [Abstract]
Tax Receivable Agreement Liability	Tax Receivable Agreement Liability The Company has a Tax Receivable Agreement with the pre-IPO owners of the LLC that provides for the payment by the Company to the pre-IPO owners (or their permitted assignees) of 85% of the amount of the benefits, if any, that the Company is deemed to realize as a result of (i) increases in tax basis and (ii) certain other tax benefits related to the Company entering into the Tax Receivable Agreement, including those attributable to payments under the Tax Receivable Agreement. These payment obligations are obligations of the Company and not of the LLC. For purposes of the Tax Receivable Agreement, the benefit deemed realized by the Company will be computed by comparing the actual income tax liability of the Company (calculated with certain assumptions) to the amount of such taxes that the Company would have been required to pay had there been no increase to the tax basis of the assets of the LLC as a result of the purchases or exchanges, and had the Company not entered into the Tax Receivable Agreement. The following table reflects the changes to the Company's Tax Receivable Agreement liability: As of September 30, 2015 As of June 30, 2015 Beginning balance $ 96,470 $ 13,636 Additions to tax receivable agreement: Follow-on Offering on July 15, 2014 — 34,028 Tender Offer on April 15, 2015 — 23,969 Secondary Offering on May 27, 2015 — 24,837 Exchange of LLC Units for Class A Common Stock 118 — Payments under tax receivable agreement — — 96,588 96,470 Less current portion under tax receivable agreement (2,969 ) (2,969 ) Ending balance $ 93,619 $ 93,501 The Tax Receivable Agreement further provides that, upon certain mergers, asset sales or other forms of business combinations or other changes of control, the Company (or its successor) would owe to the pre-IPO owners of the LLC a lump-sum payment equal to the present value of all forecasted future payments that would have otherwise been made under the Tax Receivable Agreement that would be based on certain assumptions, including a deemed exchange of LLC Units and that the Company would have sufficient taxable income to fully utilize the deductions arising from the increased tax basis and other tax benefits related to entering into the Tax Receivable Agreement. The Company also is entitled to terminate the Tax Receivable Agreement, which, if terminated, would obligate the Company to make early termination payments to the pre-IPO owners of the LLC. In addition, a pre-IPO owner may elect to unilaterally terminate the Tax Receivable Agreement with respect to such pre-IPO owner, which would obligate the Company to pay to such existing owner certain payments for tax benefits received through the taxable year of the election. As of September 30, 2015 , the Company had recorded deferred tax assets of $111,070 associated with basis differences in assets upon acquiring an interest in Malibu Boats Holdings, LLC. The aggregate tax receivable agreement liabilities of $93,619 represent 85% of the tax savings that the Company will receive in connection with the anticipated Section 754 election. In accordance with the Tax Receivable Agreement, the first payment is anticipated to occur 45 days after filing the federal tax return due on March 15, 2016.

Fair Value Measurements

Fair Value Disclosures [Abstract]
Fair Value Measurements	Fair Value Measurements In determining the fair value of certain assets and liabilities, the Company employs a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value. As defined in ASC Topic 820, Fair Value Measurements and Disclosures , fair value is the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date (i.e., the exit price). Financial assets and financial liabilities recorded on the consolidated balance sheets at fair value are categorized based on the reliability of inputs to the valuation techniques as follows: • Level 1—Financial assets and financial liabilities whose values are based on unadjusted quoted prices in active markets for identical assets. • Level 2—Financial assets and financial liabilities whose values are based on quoted prices for similar assets or liabilities in active markets; quoted prices for identical or similar assets or liabilities in non-active markets; or valuation models whose inputs are observable, directly or indirectly, for substantially the full term of the asset or liability. • Level 3—Financial assets and financial liabilities whose values are based on prices or valuation techniques that require inputs that are both unobservable and significant to the overall fair value measurement. These inputs reflect the Company’s estimates of the assumptions that market participants would use in valuing the financial assets and financial liabilities. The hierarchy gives the highest priority to Level 1 inputs and the lowest priority to Level 3 inputs. In certain cases, the inputs used to measure fair value may fall into different levels of the fair value hierarchy. In such cases, the level in the fair value hierarchy within which the fair value measurement in its entirety falls has been determined based on the lowest level input that is significant to the fair value measurement in its entirety. The Company’s assessment of the significance of a particular input to the fair value measurement in its entirety requires judgment and considers factors specific to the asset or liability. Assets and liabilities that had recurring fair value measurements were as follows: Fair Value Measurements at Reporting Date Using Total Quoted Prices in Active Markets for Identical Assets (Level 1) Significant Other Observable Inputs (Level 2) Significant Unobservable Inputs (Level 3) As of September 30, 2015: Interest rate swap not designated as cash flow hedge $ 557 $ — $ 557 $ — Total liabilities at fair value $ 557 $ — $ 557 $ — Fair value measurements for the Company’s interest rate swap are classified under Level 2 because such measurements are based on significant other observable inputs. There were no transfers of assets or liabilities between Level 1 and Level 2 as of September 30, 2015 or June 30, 2015 . The Company’s nonfinancial assets and liabilities that have nonrecurring fair value measurements include property, plant and equipment, goodwill and intangibles. In assessing the need for goodwill impairment, management relies on a number of factors, including operating results, business plans, economic projections, anticipated future cash flows, transactions and marketplace data. Accordingly, these fair value measurements fall in Level 3 of the fair value hierarchy. The Company generally uses projected cash flows, discounted as necessary, to estimate the fair values of property, plant and equipment and intangibles using key inputs such as management’s projections of cash flows on a held-and-used basis (if applicable), management’s projections of cash flows upon disposition and discount rates. Accordingly, these fair value measurements fall in Level 3 of the fair value hierarchy. These assets and certain liabilities are measured at fair value on a nonrecurring basis as part of the Company’s impairment assessments and as circumstances require.

Income Taxes

Income Tax Disclosure [Abstract]
Income Tax	Income Taxes Malibu Boats, Inc. is taxed as a C corporation for U.S. income tax purposes and is therefore subject to both federal and state taxation at a corporate level. The LLC continues to operate in the United States as a partnership for U.S. federal income tax purposes. Income taxes are computed in accordance with ASC Topic 740, Income Taxes , and reflect the net tax effects of temporary differences between the financial reporting carrying amounts of assets and liabilities and the corresponding income tax amounts. The Company has deferred tax assets and liabilities and maintains valuation allowances where it is more likely than not that all or a portion of deferred tax assets will not be realized. To the extent the Company determines that it will not realize the benefit of some or all of its deferred tax assets, such deferred tax assets will be adjusted through the Company’s provision for income taxes in the period in which this determination is made. As of September 30, 2015 , the Company had recorded no valuation allowances against deferred tax assets. The Company’s consolidated interim effective tax rate is based upon expected annual income from operations, statutory tax rates and tax laws in the various jurisdictions in which the Company operates. Significant or unusual items, including adjustments to accruals for tax uncertainties, are recognized in the quarter in which the related event occurs. The Company’s effective tax rate was 33.3% and 27.5% for the three months ended September 30, 2015 and 2014 , respectively. The principal differences in the Company's effective tax rate and the statutory federal income tax rate of 35% relate to the impact of the non-controlling interests in the LLC, which is a pass-through entity for U.S. federal tax purposes, and state taxes. The Company's effective tax rate for the three months ended September 30, 2015 and 2014 also reflects the impact of the Company's share of the LLC's permanent items such as stock compensation expense attributable to profits interests as well as nondeductible offering and acquisition related costs. Additionally, the Company's effective tax rate for the three months ended September 30, 2015 includes the benefit of the Section 199 deduction.

Stock-Based Compensation	Stock-Based Compensation On January 6, 2014, the Company’s Board of Directors adopted the Malibu Boats, Inc. Long-Term Incentive Plan (the “Incentive Plan”). The Incentive Plan, which became effective on January 1, 2014, reserves for issuance up to 1,700,000 shares of Malibu Boats, Inc. Class A Common Stock for the Company’s employees, consultants, members of its board of directors and other independent contractors at the discretion of the compensation committee. Incentive stock awards authorized under the Incentive Plan include unrestricted shares of Class A Common Stock, stock options, stock appreciation rights, restricted stock, restricted stock units, dividend equivalent awards and performance awards. As of September 30, 2015 , 1,556,728 shares remain available for future issuance under the Incentive Plan. Readers should refer to Note 13 to the fiscal 2015 audited consolidated financial statements contained in the Company's Annual Report on Form 10-K for the fiscal year ended June 30, 2015, for additional information related to the Company's awards and the Incentive Plan. The following is a summary of the changes in non-vested restricted shares for the three months ended September 30, 2015 : Number of Restricted Stock Units Outstanding Weighted Average Grant Date Fair Value Total Non-vested Restricted Stock Units as of June 30, 2015 44,775 $ 20.20 Granted 3,378 13.98 Vested (3,378 ) 13.98 Total Non-vested Restricted Stock Units as of September 30, 2015 44,775 $ 20.20 Stock compensation expense attributable to the Company's restricted shares was $340 and $487 for the three months ended September 30, 2015 and 2014, respectively. Stock compensation expense attributed to equity awards issued under the Incentive Plan and under the previously existing LLC Agreement is recognized on a straight-line basis over the terms of the respective awards and is included in general and administrative expense in the Company's unaudited condensed consolidated statement of operations and comprehensive income (loss). The cash flow effects resulting from restricted unit awards were reflected as noncash operating activities. As of September 30, 2015 and June 30, 2015 , unrecognized compensation cost related to nonvested, share-based compensation was $1,918 and $2,258 , respectively. As of September 30, 2015 , the weighted average years outstanding for unvested awards under the Incentive Plan and under the previously existing LLC Agreement were 2.9 and 1.1 years, respectively. During the three months ended September 30, 2015 , the Company withheld approximately 3,781 restricted stock awards at an aggregate cost of approximately $80 , as permitted by the applicable equity award agreements, to satisfy employee tax withholding requirements related to 11,068 restricted stock awards that vested on June 27, 2015. Restricted stock awards vesting during the first quarter include 3,378 fully vested restricted stock units issued to non-employee directors for their services as directors for the Company.

Earnings Per Share [Abstract]
Net Earnings Per Share	Net Earnings Per Share Basic net earnings per share of Class A Common Stock is computed by dividing net earnings attributable to the Company's earnings by the weighted average number of shares of Class A Common Stock outstanding during the period. The weighted average number of shares of Class A Common Stock outstanding used in computing basic net earnings per share includes fully vested restricted stock units awarded to directors that are entitled to participate in distributions to common stockholders through receipt of additional units of equivalent value to the dividends paid to Class A Common stockholders . Diluted net earnings per share of Class A Common Stock is computed similarly to basic net earnings per share except the weighted average shares outstanding are increased to include additional shares from the assumed exercise of any common stock equivalents using the treasury method, if dilutive. The Company’s LLC Units are considered common stock equivalents for this purpose. The number of additional shares of Class A Common Stock related to these common stock equivalents is calculated using the treasury stock method. The portion of consideration paid in Class A Common Stock related to the acquisition of Malibu Boats Pty. Ltd. that is subject to a time-based restriction is also included in the denominator. Basic and diluted net earnings per share of Class A Common Stock for the three months ended September 30, 2015 and 2014 have been computed as follows (in thousands, except share and per share amounts): Three Months Ended September 30, 2015 Three Months Ended September 30, 2014 Basic: Net income attributable to Malibu Boats, Inc. $ 3,558 $ 1,380 Shares used in computing basic net income per share: Weighted-average Class A Common Stock 17,869,406 14,723,265 Weighted-average participating restricted stock units convertible into Class A Common Stock 72,679 60,721 Basic weighted-average shares outstanding 17,942,085 14,783,986 Basic net income per share $ 0.20 $ 0.09 Diluted: Net income attributable to Malibu Boats, Inc. $ 3,558 $ 1,380 Net income attributable to the non-controlling interest — 618 Net income 3,558 1,998 Shares used in computing diluted net income per share: Basic weighted-average shares outstanding 17,942,085 14,783,986 Weighted-average vested and non-vested non-controlling interest units convertible into Class A Common Stock — 6,642,051 Restricted stock units granted to employees 6,750 — Diluted weighted-average shares outstanding 1 17,948,835 21,426,037 Diluted net income per share $ 0.20 $ 0.09 1 The Company excluded 1,416,973 and 46,250 potentially dilutive shares from the calculation of diluted net income per share for the three ended September 30, 2015 and 2014, respectively, as these shares would have been antidilutive. The shares of Class B Common Stock do not share in the earnings or losses of Malibu Boats, Inc. and are therefore not included in the calculation. Accordingly, basic and diluted net earnings per share of Class B Common Stock has not been presented.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies Repurchase Commitments In connection with its dealers’ wholesale floor-plan financing of boats, the Company has entered into repurchase agreements with various lending institutions for sales generated from both the U.S. and Australia operating segments. The reserve methodology used to record an estimated expense and loss reserve in each accounting period is based upon an analysis of likely repurchases based on current field inventory and likelihood of repurchase. Subsequent to the inception of the repurchase commitment, the Company evaluates the likelihood of repurchase and adjusts the estimated loss reserve and related statement of operations account accordingly. This potential loss reserve is presented in accrued liabilities in the accompanying unaudited condensed consolidated balance sheets. If the Company were obligated to repurchase a significant number of units under any repurchase agreement, its business, operating results and financial condition could be adversely affected. Repurchases and subsequent sales are recorded as a revenue transaction. The net difference between the original repurchase price and the resale price is recorded against the loss reserve and presented in cost of goods sold in the accompanying unaudited condensed consolidated statement of operations and comprehensive income (loss). During the quarter ended September 30, 2015, the Company agreed to repurchase a unit from the lender of one of its former dealers. Other than this repurchase commitment, the Company has not repurchased another unit from lenders since July 1, 2010. Accordingly, the Company did not carry a reserve for repurchases as of September 30, 2015 or June 30, 2015 , respectively. Contingencies Certain conditions may exist which could result in a loss, but which will only be resolved when future events occur. The Company, in consultation with its legal counsel, assesses such contingent liabilities, and such assessments inherently involve an exercise of judgment. If the assessment of a contingency indicates that it is probable that a loss has been incurred, the Company accrues for such contingent loss when it can be reasonably estimated. If the assessment indicates that a potentially material loss contingency is not probable but reasonably estimable, or is probable but cannot be estimated, the nature of the contingent liability, together with an estimate of the range of possible loss if determinable and material, is disclosed. Estimates of potential legal fees and other directly related costs associated with contingencies are not accrued but rather are expensed as incurred. Except as disclosed below under "Legal Proceedings," management does not believe there are any pending claims (asserted or unasserted) at September 30, 2015 (unaudited) or June 30, 2015 that will have a material adverse impact on the Company’s financial condition, results of operations or cash flows. Legal Proceedings On August 27, 2010, Pacific Coast Marine Windshields Ltd., or "PCMW," filed suit against the Company and certain third parties, including Marine Hardware, Inc., a third-party supplier of windshields to the Company, in the U.S. District Court for the Middle District of Florida seeking monetary and injunctive relief. PCMW was a significant supplier of windshields to the Company through 2008, when the Company sought an alternative vendor of windshields in response to defective product supplied by PCMW. PCMW’s amended complaint alleged, among other things, infringement of a design patent and two utility patents related to marine windshields, copyright infringement and misappropriation of trade secrets. The Company denied any liability arising from the causes of action alleged by PCMW and filed a counter claim alleging PCMW’s infringement of one of the Company's patents, conversion of two of the patents asserted against the Company, unfair competition and breach of contract. In September 2014, the Company entered into a settlement agreement with PCMW pursuant to which the Company agreed to pay $20.0 million in cash to the plaintiffs, PCMW and Darren Bach, and the parties released each other from all past and present claims. Further, the plaintiffs, including PCMW, agreed not to sue on now-existing intellectual property rights. The Company recorded a one-time charge of $20.0 million in connection with the settlement for the fiscal year ended June 30, 2014 and the Company paid $20.0 million on October 6, 2014. On October 31, 2013, the Company filed suit against Nautique Boat Company, Inc., or "Nautique," in the U.S. District Court for the Eastern District of Tennessee alleging infringement of two of the Company's patents and seeking monetary and injunctive relief. This Tennessee lawsuit is a re-filing of a California patent infringement lawsuit against Nautique that was dismissed without prejudice on October 31, 2013. On November 1, 2013, Nautique filed for declaratory judgment in the U.S. District Court for the Middle District of Florida, claiming that it has not infringed the two patents identified in the original complaint in the Tennessee lawsuit. The Tennessee court has enjoined Nautique from maintaining the Florida lawsuit which is partially duplicative. Nautique has dismissed the Florida lawsuit to comply with the Tennessee court’s ruling. On December 13, 2013, the Company amended the Company's complaint to add another of its patents to the Tennessee lawsuit. All three patents in the case relate to the Company's proprietary wake surfing technology. On June 27, 2014, Nautique filed a petition with the U.S. Patent and Trademark Office, or “PTO,” requesting institution of an Inter Partes Review, or “IPR,” of the Company’s U.S. Pat. No. 8,539,897, one of the three patents at issue in the Tennessee litigation. On February 6, 2015, the Company and Nautique entered into a Settlement Agreement (the "Nautique Settlement Agreement") to settle a lawsuit filed by the Company in the U.S. District Court for the Eastern District of Tennessee alleging infringement by Nautique of three of the Company's patents. Under the terms of the Nautique Settlement Agreement, Nautique made a one-time payment of $2,250 and entered into a license agreement for the payment of future royalties for boats sold by Nautique using the licensed technology. The parties agreed to dismiss all claims in the patent litigation and jointly request the U.S. Patent and Trademark Office to terminate the patent challenge. On February 17, 2015, the parties dismissed the patent litigation with prejudice and on February 25, 2015, the U.S. Patent and Trademark Office terminated the inter parties review proceeding. On June 29, 2015, the Company filed suit against MasterCraft Boat Company, LLC, or "MasterCraft," in the U.S. District Court for the Eastern District of Tennessee, seeking monetary and injunctive relief. The Company's complaint alleged MasterCraft's infringement of a utility patent related to wake surfing technology. MasterCraft denied liability arising from the causes of action alleged in the Company's complaint and filed a counterclaim alleging non-infringement and invalidity of the asserted patent. In August 2015, MasterCraft filed a motion for summary judgment of non-infringement, which the Company opposed. The Court has not scheduled a hearing on MasterCraft's motion. The Court also has not yet issued a scheduling order regarding the schedule for the litigation. The Company intends to vigorously pursue this litigation to enforce its rights in its patented technology and believes that MasterCraft's counterclaims are without merit. On September 30, 2015, Great Wakes Boating, Inc. filed suit against the Company, Sunny Marine, LLC, Norris Companies a/k/a Norris Docks, LLC, Wayne Wilson, Scott Davenport and certain former employees of the Company and other individuals, in the Chancery Court for Anderson County, Tennessee seeking monetary and injunctive relief. The complaint alleges breach of contract, failure to act in good faith, misrepresentation, and civil conspiracy by the Company and Messrs. Wilson, and Davenport. The Company believes the claims by Great Wakes Boating are without merit and plans to vigorously defend the lawsuit.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of presentation	Basis of Presentation The accompanying unaudited interim condensed consolidated financial statements of the Company have been prepared in accordance with U.S. generally accepted accounting principles ("GAAP") for interim condensed financial statements and with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all information and disclosures of results of operations, financial position and changes in cash flow in conformity with GAAP for complete financial statements. Such statements should be read in conjunction with the audited consolidated financial statements and notes thereto of Malibu Boats, Inc. and subsidiaries for the year ended June 30, 2015 included in the Company's Annual Report on Form 10-K. In the opinion of management, the accompanying unaudited interim condensed consolidated financial statements reflect all adjustments considered necessary to present fairly the Company’s financial position at September 30, 2015 and the results of its operations and the cash flows for the three month periods ended September 30, 2015 and September 30, 2014 . Operating results for the three months ended September 30, 2015 are not necessarily indicative of the results that may be expected for the full year ending June 30, 2016 . Certain reclassifications have been made to the prior period presentation to conform to the current period presentation. Units and shares are presented as whole numbers while all dollar amounts are presented in thousands, unless otherwise noted.
Principals of consolidation	Principles of Consolidation The accompanying unaudited condensed consolidated financial statements include the operations and accounts of the Company and all subsidiaries thereof. All intercompany balances and transactions have been eliminated upon consolidation.
Recent accounting pronouncements	Recent Accounting Pronouncements In July 2015, the FASB issued Accounting Standards Update ("ASU") No. 2015-11, Simplifying the Measurement of Inventory . This ASU changes the measurement principle for inventories valued under the first-in, first-out ("FIFO") or weighted-average methods from the lower of cost or market to the lower of cost and net realizable value. Net realizable value is defined by the FASB as estimated selling prices in the ordinary course of business, less reasonably predictable costs of completion, disposal and transportation. This ASU does not change the measurement principles for inventories valued under the last-in, first-out ("LIFO") method. This amendment is effective for fiscal years beginning after December, 15, 2016, including interim periods within those fiscal years and should be applied prospectively with earlier application permitted as of the beginning of an interim or annual reporting period. The Company is currently evaluating the impact of adopting this ASC amendment, but does not expect it will have a material impact. In April 2015, the FASB issued ASU No. 2015-05, Intangibles-Goodwill and Other-Internal-Use Software (Subtopic 350-40): Customer’s Accounting for Fees Paid in a Cloud Computing Arrangement . This ASU amended the ASC to clarify guidance regarding cloud computing arrangements and if they would be accounted for as a license of internal-use software. If the arrangement does not contain a software license, it must be accounted for as a service contract. The amendment may be applied either retrospectively or prospectively and is effective for fiscal years, and the interim periods thereafter, beginning after December 15, 2015, with early adoption permitted. The Company is currently evaluating the impact of adopting this ASC amendment, but does not expect it will have a material impact. In April 2015, the FASB issued ASU 2015-03, Interest—Imputation of Interest , which intends to simplify the presentation of debt issuance costs. Under current U.S. GAAP, debt issuance costs are reported on the balance sheet as assets and amortized as interest expense. ASU 2015-03 requires that they be presented on the balance sheet as a direct deduction from the carrying amount of the related debt liability, which is similar to the presentation of debt discounts or premiums. The costs will continue to be amortized to interest expense using the effective interest method. ASU 2015-03 is effective for annual periods and interim periods within those annual periods beginning after December 15, 2015. Early adoption is permitted. The standard requires retrospective application. The Company is currently evaluating the impact of adopting this ASC amendment, but does not expect it will have a material impact. In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers (Topic 606), which specifies how and when to recognize revenue as well as providing informative, relevant disclosures. ASU 2014-09 will become effective for fiscal years beginning after December 15, 2017. We are currently evaluating the impact on our consolidated financial statements and related disclosures. There are no other new accounting pronouncements that are expected to have a significant impact on the Company's unaudited condensed consolidated financial statements and related disclosures.
