KPMG Australia’s audit scandal has widened, with reporting that former chief executive Andrew Yates, senior partner Julian McPherson and other staff are under investigation over alleged misuse of confidential client information. The firm is also facing parliamentary scrutiny, a federal bidding ban and growing pressure from clients and regulators.

Investigations widen

KPMG’s Australian audit scandal has deepened, with reporting on Friday saying former chief executive Andrew Yates and senior partner Julian McPherson are now under investigation over alleged misuse of confidential client information.

The latest reports add to a widening regulatory and governance fallout around the firm. According to The Australian, Chartered Accountants Australia and New Zealand and ASIC are both examining the matter, and 12 KPMG staff are under scrutiny, including three partners who self-reported.

The new reporting matters because it pushes the controversy beyond a firm-level dispute and into potential professional and regulatory action against senior figures. If proven, the alleged conduct could expose individuals to discipline and KPMG to further commercial damage.

How the matter emerged

The allegations were first made public in parliament in March 2026, according to reporting. Whistleblower claims said KPMG Australia had used confidential information obtained through audits to try to win new business.

That core allegation has remained central to the scandal. The concern is not only whether client material was mishandled, but whether audit-derived information was shared or used in ways that threatened confidentiality and audit independence.

Reporting has linked the issue to major clients including Lendlease, as well as other companies named in background coverage such as Macquarie Group, Westpac, Dexus and Optus. The allegation has also sharpened scrutiny of the consulting and accounting sector after the PwC tax leak affair.

Leaders and regulators

Yates resigned on May 29, according to reporting, and McPherson also stepped down in the course of the scandal. The latest developments suggest both men remain part of the investigative focus even after leaving senior roles.

The Australian report said the investigations are being carried out by CA ANZ and ASIC. That raises the possibility of professional discipline, sanctions or other enforcement outcomes, although those processes are still ongoing and no final findings have been announced.

KPMG chairman Martin Sheppard has said the breaches were isolated incidents. That remains the firm’s public position, even as the number of people under scrutiny has expanded.

Client and political fallout

The scandal has already cost KPMG business. Lendlease has replaced its auditor after executives described the conduct as a fundamental breach of trust, according to reporting, and said the firm had inappropriately shared internal board documents.

The controversy has also moved into politics and public administration. Senator Barbara Pocock referred KPMG to the National Anti-Corruption Commission over the alleged misuse of confidential data, and the federal government imposed a three-month ban on KPMG bidding for new federal work.

Finance Minister Katy Gallagher has said, according to reporting, that there is no direct evidence tying the misconduct to federal contracts. Assistant Treasurer Daniel Mulino has said the government is reviewing broader regulatory arrangements for professional partnerships.

Parliamentary pressure

KPMG is also facing a parliamentary inquiry that has become another major pressure point. Reporting says the firm has refused to provide some documents, citing legal professional privilege, ahead of hearings.

That stance could intensify friction with lawmakers if the inquiry continues to seek answers about how the allegations arose, who knew what and when, and how the firm handled the whistleblower claims.

The present dispute is therefore no longer just about one client relationship or one audit issue. It now spans professional discipline, possible regulatory enforcement, procurement consequences, parliamentary scrutiny and the broader question of how partnership firms police confidentiality.

What happens next

The parliamentary inquiry is expected to keep taking evidence from current and former KPMG figures.

Regulators may also clarify whether the conduct described in reporting leads to formal action against the individuals under investigation. CA ANZ’s process could determine whether discipline, suspension or expulsion follows, while ASIC’s probe could test whether enforcement action is warranted.

The government’s broader review of partnership regulation is also still in train. For KPMG, that means the commercial and reputational risk is not limited to the current three-month federal bidding ban, and further client or contract changes could follow if more details emerge.

For now, the central facts are settled enough for a public article: the allegations involve audit-derived confidential information, former senior leaders are now under investigation, and the fallout is spreading across regulators, parliament and the firm’s client base.
