Greens Senator Barbara Pocock led the interrogation during a day-long public hearing, drawing direct parallels between the current KPMG controversy and the 2023 PwC tax leaks scandal. At the heart of the probe is the allegation that KPMG misused confidential board papers from Lendlease to secure audit tenders for Westpac and Dexus. This failure of internal governance resulted in the recent resignations of the firm’s Australian CEO, Andrew Yates, and its audit chief.

The inquiry focused on the firm's structure, which currently exempts it from the strict oversight of the Australian Securities and Investments Commission. Labor Senator Deborah O'Neill challenged the firm’s leadership on whether systemic rot had replaced individual lapses in judgment. Yates defended the organization as a complex entity prone to human error, yet admitted the firm failed to protect a whistleblower who faced repeated computer surveillance and severe career damage. Senator Paul Scarr noted the whistleblower suffered a horrendous personal and mental cost, a sentiment Yates acknowledged by conceding that the firm simply did not get it right.
