KPMG Faces First Major Client Loss as Whistleblower Scandal Deepens

KPMG Australia is facing a growing corporate crisis after chief executive Andrew Yates and senior partner Julian McPherson resigned amid allegations that confidential client information was improperly accessed and potentially used to secure new business opportunities.

The scandal has now triggered the first major client fallout, with property and construction giant Lendlease reviewing its long-standing relationship with KPMG.

The company confirmed it will assess its audit arrangements after completing its 2026 financial reporting process, raising the possibility that KPMG could lose a client relationship that has lasted nearly seven decades.

The controversy began after an anonymous whistleblower lodged complaints in 2024, alleging that KPMG partners accessed confidential board papers from Lendlease and used the information to pursue audit and consulting work with other companies, including Westpac and Dexus. Senator Deborah O’Neill later raised the allegations in Parliament, intensifying public scrutiny of the firm.

In March, Lendlease chief executive Tony Lombardo told KPMG that the conduct of its employees was “not acceptable” after the firm confirmed boardroom documents had been accessed. KPMG reportedly received more than $10 million in fees from Lendlease last year.

Initially, KPMG told Lendlease that its investigation found no wrongdoing. However, after the allegations became public, the firm admitted one of its audit partners had accessed confidential board documents, while maintaining the material provided no competitive advantage.

The crisis has drawn comparisons with the PwC tax leaks scandal, where confidential government tax information was allegedly used to benefit corporate clients. That controversy resulted in major business losses for PwC and significant restructuring of its operations.

Regulatory and Client Scrutiny Intensifies

The fallout is spreading across KPMG’s client base. Westpac has sought additional information from the firm regarding the allegations, while scrutiny is increasing over KPMG’s upcoming audit appointments with major companies, including Macquarie Group, Brambles, and Wesfarmers. Macquarie’s audit mandate is considered one of Australia’s most valuable.

The Parliamentary Joint Committee (PJC), led by Senator O’Neill, is expected to hold a public hearing this month and seek access to KPMG’s previous investigations, which had concluded there was no evidence of misconduct.

KPMG chairman Martin Sheppard requested a private hearing, a move criticised by O’Neill, who argued the matter should be examined publicly.

Meanwhile, the Australian Securities and Investments Commission (ASIC) has launched a preliminary investigation into the conduct of several KPMG auditors. Law firm Allens has also been engaged to independently review the whistleblower allegations and reassess conclusions reached in earlier investigations.

As pressure builds from regulators, lawmakers and clients, KPMG faces one of the most significant reputational challenges in its Australian operations, with questions growing over governance, auditor independence and the handling of whistleblower complaints.
