KPMG Australia CEO resigns over whistleblower scandal

What happened: KPMG Australia's CEO Andrew Yates resigned following a whistleblower scandal. The firm admitted to leaking confidential Optus information to win an audit contract with Telstra, surveilling a whistleblower's laptop, and mishandling previous whistleblower allegations. Audit partners Paul Rogers and Eileen Hoggett also exited, and KPMG announced governance reforms.

Market impact: The scandal has shaken investor confidence in KPMG Australia, potentially impacting its market share and valuation. It also raises questions about the broader accounting industry's ethical standards, which could drive regulatory scrutiny and affect other major players like PwC, EY, and Deloitte.

What to watch next: KPMG's board meeting on March 15, where further leadership changes and governance updates are expected. Additionally, the Australian Securities and Investments Commission's (ASIC) response to the scandal, which could lead to regulatory action or industry-wide investigations.
