Australian regulator scrutinizes Big Four audit practices

The Australian Securities and Investments Commission (ASIC) is now examining how these firms process whistleblower reports and internal grievances tied to their external audit services. The investigation specifically targets whether these firms have policies in place to detect and prevent auditor misconduct, including the unauthorized sharing of sensitive corporate information. While ASIC continues its formal probe into KPMG, the regulator is also engaging with the government’s broader reform agenda to address systemic failures in the accounting sector.

Pressure on the industry has mounted since March, when Senator Deborah O'Neill disclosed allegations that KPMG utilized confidential LendLease board papers to bolster its bids for tenders at Westpac and Dexus. Although KPMG’s internal investigation failed to substantiate those claims, the firm’s leadership faced consequences. In late May, KPMG Australia CEO Andrew Yates resigned, citing systemic failures in the firm’s handling of whistleblower reports regarding data security. The government is currently weighing potential structural changes, including the possibility of breaking up the Big Four firms to ensure stricter oversight.
