On January 10, 2018, the Audit Committee (the “Audit Committee”) of the Board of Directors of SITO Mobile Ltd. (the “Company”)  dismissed  RBSM LLP (“RBSM”) as independent registered public accounting firm for the Company.

The audit report of RBSM on the consolidated financial statements of the Company as of December 31, 2016 and 2015 did not contain any adverse opinion or disclaimer of opinion, nor were they qualified or modified as to uncertainty, audit scope or accounting principles.

During the Company’s fiscal years ended December 31, 2016, and December 31, 2017 and through the date of dismissal of RBSM, there have been no “disagreements” (as such term is described in Item 304(a)(1)(iv) of Regulation S-K) with RBSM on any matter of accounting principle or practices, financial statement disclosure or auditing scope or procedure, which disagreements if not resolved to the satisfaction of RBSM would have caused RBSM to make reference thereto in their reports on the consolidated financial statements for such years.

During the fiscal years ended December 31, 2016 and 2015 and through the date of dismissal of RBSM, none of the” reportable events” described in Item 304(a)(1)(v) of Regulation S-K occurred.

The Company provided RBSM with a copy of the foregoing disclosures and requested that RBSM furnish the Company with a letter addressed to the Securities and Exchange Commission stating whether or not it agrees with the above statements. A copy of RBSM’s letter dated January 12, 2018 is attached as Exhibit 16.1 hereto.

On January 10, 2018, the Audit Committee completed a competitive process to select the Company’s independent registered public accounting firm for the fiscal year ending December 31, 2017. As a result of this process, the Audit Committee appointed BDO USA, LLP (“BDO”) as the Company’s independent registered public accounting firm for the fiscal year ending December 31, 2017.

During the Company’s fiscal years ended December 31, 2016, and December 31, 2017 and through January 12, 2018, neither the Company nor anyone on its behalf consulted with BDO regarding (i) the application of accounting principles to a specified transaction, either completed or proposed, or the type of audit opinion that might be rendered on the Company’s consolidated financial statements, and no written report or oral advice was provided by BDO to the Company that BDO concluded was an important factor considered by the Company in reaching a decision as to the accounting, auditing or financial reporting issue, or (ii) any subject of a disagreement (as defined in Item 304(a)(1)(iv) of Regulation S-K) or any reportable events (as defined in Item 304(a)(1)(v) of Regulation S-K).
