Australia's top corruption fighter is expected to face fiery questions from senators about his turbulent three years in the job, less than 24 hours after announcing his resignation.
National Anti-Corruption Commissioner Paul Brereton is scheduled for his first appearance before a senate estimates committee on Tuesday.
He's likely to be grilled over a series of alleged conflicts of interest which ultimately led to him announcing plans to leave the agency on July 6.
Mr Brereton said ongoing questions about the conflicts had distracted from the work of the National Anti-Corruption Commission, with politicians involved in setting up the agency calling for a "reset" in leadership.
In 2025, the former war crimes investigator stepped away from all defence-related corruption referrals to avoid any perceived conflict of interest, after revelations he was continuing to work with the inspector general of the Australian Defence Force as a consultant.
