KPMG Australia has announced a sweeping leadership shake‑up after a scandal involving the misuse of confidential client data to chase audit contracts. The firm said Martin Sheppard will exit soon and that an independent chair will replace him. Senior partners Paul Rogers and Eileen Hoggett also depart amid allegations that data from major Australian firms was leveraged in bids.

Three weeks earlier, KPMG’s chief executive Andrew Yates and audit leader Julian McPherson stepped down after the firm admitted its investigations into a whistleblower’s claims had fallen short. Sheppard testified before a parliamentary committee, where senators demanded more transparency on internal and external probes. He agreed to hand over documents, but criticism over the firm’s response intensified.

The departures come less than a week after KPMG faced scrutiny similar to PwC’s “tax leaks” scandal, prompting a fresh “lessons learned” review by Principia Advisory. KPMG’s interim chief Stan Stavros said the firm must address unethical behaviour and protect the whistleblower’s interests. Investors will watch how the overhaul affects client confidence and future audit contracts.

KPMG’s overhaul signals the Big Four’s tightening governance amid growing regulatory pressure. Australian auditors now face stricter data‑protection rules and heightened scrutiny from the Australian Securities & Investments Commission. The firm’s action plan, announced Tuesday, includes a new audit‑leadership review and a commitment to publish the Principia findings. Market participants will assess whether these steps restore credibility and safeguard future revenue streams.
