Australia Moves to Increase Scrutiny of Big Four Accounting Firms Amid Scandals

The Australian government announced on Thursday it will increase its oversight of the Big Four accounting firms, directing the country's corporate regulator to tighten rules after a wave of scandals damaged the industry's reputation. The move signals a tougher regulatory environment for the nation's audit and consulting sectors.

Regulatory Overhaul Planned

In a statement, the government said it has instructed the Australian Securities and Investments Commission (ASIC) to improve the regulation of accounting and auditing firms. The goal is to enhance "the accountability, transparency and oversight of the audit sector."

While specific new measures were not detailed, the government has recently floated several proposals. These include bringing the firms directly under ASIC's regulatory purview and equipping the agency with stronger enforcement powers and penalties. The more drastic option of breaking up the Big Four firms is also under consideration, according to the government.

A Pattern of Misconduct

The directive follows several significant governance failures involving all of the Big Four firms in Australia. These incidents have eroded public trust and prompted calls for reform.

• KPMG: The most recent case involves accusations that staff misused confidential information to secure contracts.
• PwC: In 2023, the firm was embroiled in a major scandal after it was revealed partners had shared confidential government tax policy details to win new clients.
• EY: In June, two employees were reportedly dismissed after allegedly accessing the personal banking information of the prime minister.
• Deloitte: The firm issued an apology last year after academics discovered a report it prepared for a government department included AI-generated fabrications.

Broader Mandate for ASIC

Beyond the audit sector, ASIC has also been instructed to enforce high standards across Australia’s pension system and to take action against corporate greenwashing. For investors and financial markets, this signals a broad-based push for greater corporate accountability and more stringent enforcement across the financial services landscape.
