Report of Independent Registered Public Accounting Firm

The Board of Directors

Perpetual Trustee Company Limited:

We have examined managements assessment, included in the accompanying Management Assessment, that Perpetual Trustee Company Limited (the Company)
complied with the servicing criteria set forth in Item 1122(d)(2)(ii), 1122(d)(3)(ii), 1122(d)(3)(iii) and 1122(d)(3)(iv) of the Securities and Exchange Commissions Regulation AB for asset-backed securities transactions that are backed by
auto finance receivables for which the Company serviced as issuer trustee (the Platform) as of and for the year ended 31 March 2014. With respect to applicable servicing criteria 1122(d)(2)(ii), 1122(d)(3)(ii), 1122(d)(3)(iii), and
1122(d)(3)(iv), the Company has determined that there were no activities performed during the year ended 31 March 2014 with respect to SMART ABS Series 2014-1US Trust, because there were no occurrences of events that would require the Company
to perform such activities. The Companys management has determined that all other criteria set forth in Item 1122(d) are not applicable to the Company because the Company does not perform activities with respect to the Platform relating
to those criteria. Appendix B to the Management Assessment identifies the individual trusts defined by management as constituting the Platform. Management is responsible for the Companys compliance with the servicing criteria. Our
responsibility is to express an opinion on managements assessment about the Companys compliance based on our examination.

Our examination was
conducted in accordance with the standards of the Public Company Accounting Oversight Board (United States) and, accordingly, included examining, on a test basis, evidence about the Companys compliance with the servicing criteria specified
above and performing such other procedures as we considered necessary in the circumstances. Our examination included testing selected asset-backed transactions and securities that comprise the Platform, testing selected servicing activities related
to the Platform, and determining whether the Company processed those selected transactions and performed those selected activities in compliance with the servicing criteria. Furthermore, our procedures were limited to the selected transactions and
servicing activities performed by the Company during the period covered by this report. Our procedures were not designed to determine whether errors may have occurred either prior to or subsequent to our tests that may have affected the balances or
amounts calculated or reported by the Company during the period covered by this report for the selected transactions or any other transactions. We believe that our examination provides a reasonable basis for our opinion. Our examination does not
provide a legal determination on the Companys compliance with the servicing criteria.

In our opinion, managements assessment that Perpetual
Trustee Company Limited complied with the aforementioned servicing criteria as of and for the year ended 31 March 2014 is fairly stated, in all material respects.
