KPMG Australia COO steps aside amid audit leak scandal investigations

KPMG Australia’s audit leak scandal has now taken out a third senior figure, with chief operating officer Eileen Hoggett stepping aside while investigations continue. Hoggett will return to a full-time audit partner role, but her exit from the executive line deepens the churn inside a firm already trying to steady staff, clients and regulators after days of upheaval.

The move follows the immediate resignations of chief executive Andrew Yates and national managing partner of audit and assurance Julian McPherson on 29 May 2026. KPMG has appointed Stan Stavros as interim CEO, but the broader message to employees is harder to control: the firm’s top management is changing in real time while investigators continue to examine how a whistleblower complaint was handled.

The complaint was first raised in May 2024 and later aired publicly by Labor Senator Deborah O’Neill under parliamentary privilege this year. KPMG has said its earlier internal and external reviews did not substantiate the claims, but the board has now conceded the firm fell short in its treatment of the whistleblower, the rigor of its investigations and the leadership response to the allegations. That is a serious admission for a professional services partnership built on trust, particularly in audit, where credibility is the product.

The allegations go to the heart of that trust. They include claims that confidential Lendlease board papers were used to support bids for audits of Westpac and Dexus, and that client documents were inappropriately shared internally. Lendlease is the only client publicly confirmed so far to have said KPMG misused its documents. For audit teams, the issue is not just reputational damage but the day-to-day strain of working under scrutiny while clients question controls that are supposed to protect their information.

Regulatory pressure is building too. The Australian Securities and Investments Commission has opened a preliminary investigation into the conduct of three KPMG registered company auditors. KPMG has also brought in a law firm and a corporate ethics consultant to review its whistleblower policies and processes, and further disciplinary action remains possible if the ongoing investigations surface more issues.

The scandal has drawn obvious comparisons with PwC Australia’s tax leaks affair in 2023, which triggered parliamentary hearings, employee departures and tougher oversight across the sector. For KPMG, the question now is whether this is only another leadership turnover or a deeper culture crisis that will affect retention, recruitment and the firm’s ability to reassure clients that its controls work when they matter most.
