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, 2017, 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 March 31, 2018, and the results of its operations for the nine month periods ended March 31, 2018 and March 31, 2017, and its cash flows for the nine month periods ended March 31, 2018 and March 31, 2017. Operating results for the nine months ended March 31, 2018, are not necessarily indicative of the results that may be expected for the full year ending June 30, 2018. 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 May 2014, the FASB and International Accounting Standards Board jointly issued a final standard on revenue recognition, Accounting Standards Update ("ASU") 2014-09, Revenue from Contracts with Customers (Topic 606), which outlines a single comprehensive model for entities to use in accounting for revenue arising from contracts with customers. This standard will supersede most current revenue recognition guidance. Under the new standard, entities are required to identify the contract with a customer; identify the separate performance obligations in the contract; determine the transaction price; allocate the transaction price to the separate performance obligations in the contract; and recognize the appropriate amount of revenue when (or as) the entity satisfies each performance obligation. The standard is effective for fiscal years beginning after December 15, 2017. Entities have the option of using either the retrospective or cumulative effect transition method. The Company expects to adopt ASU 2014-09 for the Company's fiscal year beginning July 1, 2018 and expects to adopt the guidance using the modified retrospective approach. The Company has completed a preliminary assessment of the impact of ASU 2014-09 and other related ASU's, and does not anticipate that the impact of adoption will have a material impact to the Company's financial statements, accounting policies or processes. The Company anticipates that it will have to expand its revenue related disclosures as a result of adopting this ASU. In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842). This guidance establishes a right-of-use (“ROU”) model that requires a lessee to record a ROU asset and a lease liability on the balance sheet for all leases with terms longer than 12 months. Leases will be classified as either finance or operating, with classification affecting the pattern of expense recognition in the statement of operations and comprehensive income. The new standard is effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. A modified retrospective transition approach is required for lessees for capital and operating leases existing at, or entered into after, the beginning of the earliest comparative period presented in the financial statements, with certain practical expedients available. The Company is currently assessing the potential impact of this ASU on its consolidated financial statements and footnote disclosures. In August 2016, the FASB issued ASU 2016-15, Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments. This ASU is effective for fiscal years beginning after December 15, 2017 and interim periods within those fiscal years with early adoption permitted. This guidance provides specific classification of how certain cash receipts and cash payments are presented in the statement of cash flows. The ASU should be applied using a retrospective transition method. If it is impracticable to apply the amendments retrospectively for some of the cash flow issues, the amendments for those issues should then be applied prospectively at the earliest date practicable. The Company is currently assessing the potential impact of this ASU on its presentation of the consolidated statement of cash flows. In January 2017, the FASB issued ASU 2017-01, Business Combinations (Topic 805): Clarifying the Definition of a Business. The guidance clarifies the definition of a business that provides a two-step analysis in the determination of whether an acquisition or derecognition is a business or an asset. The update removes the evaluation of whether a market participant could replace any missing elements and provides a framework to assist entities in evaluating whether both an input and a substantive process are present. This guidance is effective for annual reporting periods beginning after December 15, 2017, including interim periods within those annual reporting periods and early adoption is permitted for transactions that meet specified criteria. This guidance is to be applied on a prospective basis for transactions that occur after the effective date. There are no other new accounting pronouncements that are expected to have a significant impact on the Company's consolidated financial statements and related disclosures.
