Background on Brereton’s Appointment and Controversy
Paul Brereton was appointed inaugural commissioner of the National Anti‑Corruption Commission (NACC) in 2021, tasked with overseeing integrity across the Commonwealth. Shortly after taking office, questions emerged about his potential conflicts of interest, particularly his ongoing role as an army reserve officer and his work with the Inspector‑General of the Australian Defence Force. These dual roles prompted scrutiny over whether his official duties were being compromised by personal or professional affiliations.
The October 2024 NACC Inspector Finding
In October 2024, the NACC’s internal inspector—the body responsible for monitoring the commission’s own conduct—determined that Brereton had engaged in misconduct. The finding centred on his involvement in proceedings that blocked further investigation into Kathryn Campbell, then‑secretary of the Human Services Department and a former army reserve colleague of Brereton. The inspector concluded that Brereton’s participation created an unacceptable conflict, given his personal connection to Campbell.
Attorney‑General’s Reprimand and Defence Links
Following the inspector’s report, federal Attorney‑General Michelle Rowland reprimanded Brereton for failing to adequately address the nature of his continuing ties to the defence establishment. The reprimand highlighted concerns that Brereton had not fully disclosed the extent of his work for the Inspector‑General of the Australian Defence Force, raising doubts about his impartiality in matters affecting defence personnel.
Senate Estimates Exchange with Senator Shoebridge
During a tense Senate estimates hearing, Greens senator David Shoebridge pressed Brereton on transparency regarding his defence links. Shoebridge argued that Brereton’s failure to reveal detailed information exemplified a broader problem of opacity within the NACC. Brereton countered that he had disclosed the existence of the relationship and maintained that colleagues inside the commission did not require specifics of the less than 30 hours of work he claimed to have performed over three years.
Brereton’s Position on Responsibility
When asked whether his conduct had fallen short of the expected standards, Brereton replied unequivocally, “No, I do not.” He did concede, however, that “everyone contributes to their own downfall, if you like, in some ways,” suggesting a modest acknowledgment of personal role in the events leading to his resignation, while stopping short of accepting blame for any breach of public trust.
Reason for Resignation
Brereton stated that his decision to step down on July 6 was not driven by the prospect of adverse findings from ongoing investigations. Instead, he described the prolonged scrutiny—spanning roughly two years—as a distraction that impeded both his effectiveness and the agency’s functioning. He emphasized that no formal loss of confidence had been communicated by the Albanese government.
Defense of the Robo‑Debt Misconduct Finding
Brereton mounted a robust defence of the earlier officer‑misconduct finding related to the NACC’s abandoned decision not to pursue officials identified by the Robo‑debt royal commission. He argued that the definition of misconduct had become excessively broad, causing staff to fear even minor factual or legal errors. According to Brereton, this climate of fear undermines the commission’s ability to operate effectively, as employees become paralyzed by the prospect of punitive findings.
Impact on NACC Staff Culture
Expanding on his concerns, Brereton warned that the current environment fosters a culture where employees are “terrified of making any mistake of fact or law.” He contended that such apprehension stifles initiative and prudent decision‑making, ultimately harming the very integrity the NACC is meant to uphold. His remarks highlighted a tension between enforcing high ethical standards and maintaining a functional, resilient workforce.
Deputy Commissioner Nicole Rose’s Perspective
Deputy Commissioner Nicole Rose, who is also set to leave her role later this month, asserted that the controversy surrounding Brereton did not influence her own resignation decision. She framed her departure as unrelated to the ongoing governance issues, suggesting that personal or professional factors distinct from the Brereton situation prompted her exit.
Broader Implications for the NACC
The episode underscores the challenges faced by Australia’s newest anti‑corruption institution in establishing credibility while navigating internal governance dilemmas. Brereton’s tenure illustrates how perceived conflicts, transparency debates, and staff morale can intertwine, affecting public confidence in anti‑corruption bodies. Moving forward, the NACC will need to balance rigorous accountability mechanisms with a workplace culture that encourages diligent, fearless execution of its mandate.
End of summary.
