Background on Paul Brereton’s Tenure
Paul Brereton was appointed the inaugural commissioner of the National Anti‑Corruption Commission (NACC) in 2023, tasked with establishing the body’s independence and setting standards for integrity across the Commonwealth public sector. Prior to this role, he served as an Assistant Inspector‑General in the Australian Defence Force, a Judge of the NSW Court of Appeal, and a major general in the ADF Reserves. His extensive legal and military background was initially viewed as an asset for the new anti‑corruption watchdog. Over three years, Brereton oversaw the assessment of more than 92 % of the 7,624 referrals received, claiming that the NACC’s mere existence had already positively influenced behaviour within government agencies.
The Inspector’s Report on Robodebt Referrals
A pivotal moment in Brereton’s tenure arrived when the NACC’s inspector examined the commission’s decision not to investigate referrals stemming from the Robodebt royal commission. The report found that Brereton had declared a “close association” with one individual named in those referrals yet failed to remove himself from the related decision‑making process. Instead, he delegated the matter to a deputy, which the inspector deemed insufficient. The report concluded that Brereton should have recused himself entirely, characterizing his conduct as misconduct under the NACC Act 2022—though not unlawful, it arose from a mistake of law or fact.
Conflict‑of‑Interest Findings and Defence Links
Beyond the Robodebt issue, Brereton’s resignation drew attention to his ongoing Defence‑force connections. Revelations surfaced that he had twice been granted special permission to remain in the army reserves past the standard retirement age to provide high‑level assistance to authorities working on the Afghanistan war‑crimes inquiry. These arrangements raised further concerns about perceived conflicts of interest, especially given the NACC’s mandate to oversee corruption allegations involving defence contractors and personnel. Brereton had previously pledged to step away from all defence‑related corruption referrals after acknowledging difficulties managing such conflicts.
Brereton’s Statement on Resignation
In announcing his resignation, effective 6 July, Brereton emphasized that the intense public focus on his personal conduct was diverting attention from the NACC’s core mission of strengthening integrity in the Commonwealth public sector. He denied any wrongdoing but asserted that, with the commission now staffed by competent personnel and equipped with robust processes, it was an appropriate moment to step aside. Brereton highlighted the NACC’s achievements, including its education and engagement programs that have fostered a stronger integrity culture across government agencies.
Political Reactions: Support and Criticism
Attorney‑General Michelle Rowland thanked Brereton for his leadership, acknowledging his contributions to establishing the NACC as its inaugural commissioner. In contrast, Greens Senator David Shoebridge, who had long called for Brereton’s departure, argued that the commissioner’s inability to manage conflicts of interest—particularly regarding the Robodebt scandal—had eroded public trust and hampered the commission’s effectiveness. Independent Senator David Pocock echoed this sentiment, stating that too many perceived conflicts and decisions out of step with community expectations had necessitated the inspector’s repeated interventions. Independent Indi MP Helen Haines welcomed the resignation but stressed that the NACC still needed to improve transparency, communication, and public confidence to fulfil its anti‑corruption mandate.
Implications for the NACC’s Future
Brereton’s exit arrives just before his scheduled appearance at Senate estimates, a hearing prompted by a successful Greens motion. The timing underscores the pressure on the NACC to demonstrate accountability and restore credibility. With the commissioner role now vacant, the government must appoint a successor who can navigate the delicate balance between maintaining rigorous oversight and avoiding perceptions of bias, especially concerning defence‑related matters. The NACC’s ongoing work—processing thousands of referrals and promoting integrity training—will continue, but its leadership will need to prioritize clear communication and transparent decision‑making to rebuild trust among stakeholders and the broader public.
Assessment of the NACC’s Impact to Date
Despite the controversy surrounding its leadership, the NACC has reported substantial activity since its inception. Over 7,600 referrals have been received, with more than 92 % assessed, indicating a high volume of engagement from agencies and whistleblowers. Brereton pointed to the commission’s “education and engagement program” as a key factor in enhancing integrity culture across the public sector. These initiatives aim to prevent corrupt practices before they occur, complementing the NACC’s investigative functions. The challenge moving forward will be to ensure that such preventive work is not overshadowed by leadership scandals and that the commission’s reputation for impartiality remains intact.
Conclusion: A Pivotal Moment for Integrity Oversight
Paul Brereton’s resignation marks a pivotal moment for the National Anti‑Corruption Commission. While his tenure saw the establishment of essential processes and a notable volume of referral assessments, repeated concerns about conflict‑of‑interest management and defence‑related associations ultimately undermined confidence in his leadership. The inspector’s findings on the Robodebt referrals served as the catalyst for his departure, highlighting the need for strict adherence to recusal protocols when personal associations arise. As the NACC seeks a new commissioner, the focus must shift toward reinforcing transparency, improving communication with the public, and demonstrating that the body can operate free from the perception of undue influence. Only then can the commission fully realize its mandate to strengthen integrity across the Commonwealth public sector and restore the trust essential for effective anti‑corruption oversight.
