The KPMG Australia scandal began with a whistleblower’s 2024 allegations that senior partners misused confidential Lendlease board documents to gain an unfair edge in winning major audit mandates, including Westpac.
The story exploded into the open in 2026 after parliamentary revelations, a firm admission that internal investigations “fell short,” multiple leadership exits, fresh admissions of further breaches (including Optus-related material), regulator action, and mounting client and government fallout.
It also fits a broader Australian pattern, in which the Big Four have been forced to confront the consequences of treating confidentiality, independence, and oversight as problems to manage after the fact rather than standards to protect from the start.
The scandal has put reform back on the table, reviving proposals that were floated after the PwC tax leaks scandal but went nowhere at the time — including tougher independence rules, stronger whistleblower protections, tighter oversight, and a harder line on separating audit from consulting.
Timeline of a Scandal
10 October 2023 — Seven people from KPMG’s audit business meet to help prepare partner Kim Lawry for the Westpac audit tender. During the meeting, confidential material taken from Lendlease board papers is displayed, including an assessment of rival bids submitted by EY and PwC.
6 November 2023 — The “Lunchgate” incident occurs at KPMG’s Barangaroo office, during KPMG’s pursuit of the Dexus external audit. According to the whistleblower, partner Jeff O’Sullivan said he would go to lunch and leave his laptop open on confidential Dexus internal-audit material so members of the bid team could view it. KPMG later said the remark was intended as a joke and that it found no evidence the information was actually shared, but sanctioned O’Sullivan for making an inappropriate remark.
Late 2023–March 2024 — Westpac audit tender raises conflict-of-interest questions.
During
Westpac’s audit tender, Peter Nash, Westpac’s audit committee chair and
a former KPMG Australia national chairman, attended audit pitch
meetings. KPMG chair Martin Sheppard later told a parliamentary hearing
that Nash had stayed at his house during the pitching process,
describing him as a long-standing friend. Westpac said Nash declared his
KPMG links and was not on the selection committee, but later
acknowledged the perception of bias created by those relationships.
