Amendment Description	This Amendment No. 1 on Form 10-Q/A (this “Form 10-Q/A") amends and restates certain items noted below in the Quarterly Report on Form 10-Q of Lonestar Resources US Inc. (the “Company”) for the quarter ended March 31, 2018, as originally filed with the Securities and Exchange Commission on May 14, 2018 (the “Original Filing”). This Form 10-Q/A amends the Original Filing to reflect the correction of an error in the previously-reported unaudited condensed consolidated financial statements related to the Company’s depreciation, depletion and amortization (“DD&A”) expense calculation. See Note 2 to the Condensed Consolidated Financial Statements included in Item 1 for additional information and a reconciliation of the previously reported amounts to the restated amounts. For the convenience of the reader, this Form 10-Q/A sets forth the Original Filing, as amended, in its entirety; however, this Form 10-Q/A amends and restates only the following financial statements and disclosures that were impacted from the correction of the error:  Part I, Item 1 – Financial Statements  Part I, Item 2 – Management’s Discussion and Analysis of Financial Condition and Results of Operations  Part I, Item 4 – Controls and Procedures  Part II, Item 6 – Exhibits  Signatures The Company’s Chief Executive Officer and Chief Accounting Officer have provided new certifications dated as of the date of this filing in connection with this Form 10-Q/A (Exhibits 31.1, 31.2, 32.1 and 32.2), and the Company has provided its revised consolidated financial statements formatted in Extensible Business Reporting Language (XBRL) in Exhibit 101. Except as described above, no other changes have been made to the Original Filing. This Form 10-Q/A speaks as of the date of the Original Filing and does not reflect events that may have occurred after the date of the Original Filing or modify or update any disclosures that may have been affected by subsequent events. The Company is also concurrently filing an amended Annual Report for the year ended December 31, 2017 and an amended Quarterly Report for the period ended June 30, 2018 to restate the previously issued annual and interim financial statements due to the accounting error described above.
