Australia directs ASIC to tighten Big Four accounting oversight

The Australian government directed corporate regulators to increase oversight of the Big Four accounting firms.
The move follows recent scandals across Deloitte, EY, KPMG, and PwC involving confidential data misuse and fabrication.
Officials have proposed expanding regulator powers, raising financial penalties, and potentially breaking up the major firms.

The Australian government has directed the Australian Securities and Investments Commission to increase its oversight and regulation of the Big Four accounting firms following a series of high-profile industry scandals.

The regulatory push follows recent misconduct allegations against KPMG staff regarding the misuse of confidential information to secure contracts, alongside earlier scandals involving confidential tax leaks at PwC and AI-generated fabrications in a Deloitte report.

The government stated that the directive aims to improve accountability, transparency, and oversight across the audit sector, with proposed measures including stronger penalties and potential options to break up the major firms.

Under the new mandate, the regulator will examine audit sector whistleblower complaints while continuing its specific investigation into KPMG.

Following the announcement, the market reaction across the unlisted partnership structures of the Big Four firms remains untraded on public stock exchanges.

The recent government action builds on a pattern of governance failures in Australia, including EY sacking two employees in June after they allegedly accessed the prime minister's personal banking details.

Alongside accounting oversight, the government instructed the regulator to enforce higher standards within the pension system, deter corporate greenwashing, and maintain effective financial market infrastructure.
