NACC watchdog drops complaint investigations into Brereton after resignation

The National Anti-Corruption Commission’s inspector has discontinued two complaint investigations into former commissioner Paul Brereton, ending a months-long integrity row inside the federal watchdog.

Inspector Gail Furness said on Wednesday, 8 July 2026, that she had closed the matters after deciding the extra public expense needed to complete the draft reports could not be justified. She also said Brereton’s resignation was a factor, and that the systemic issues identified in the probes had already been satisfactorily addressed.

The decision leaves the NACC without a final public finding on two internal complaints, but it also removes an immediate source of pressure on a commission already in the middle of a leadership reset.

Why the investigations ended

Furness said the draft reports in both matters were partly contested, which meant further work would be needed to finish them. She concluded that the cost of continuing was not justified in the circumstances.

That reasoning places cost and proportionality at the centre of the decision. It also suggests the inspector weighed the value of completing formal findings against the fact that Brereton was no longer in office and the underlying problems had already been dealt with.

Furness said the systemic issues uncovered in the investigations had been addressed to her satisfaction. That was a key part of the justification for discontinuing the probes.

What the two probes covered

One investigation concerned Brereton’s handling of conflicts of interest at Defence, including undeclared Defence-related interests while he was overseeing referrals involving the department.

The other involved a separate confidential complaint about Brereton’s conduct in relation to two NACC operations.

Together, the complaints placed the commission’s first boss under scrutiny over both external conflict management and internal operational conduct. That made the case especially sensitive for an agency built around public confidence in integrity enforcement.

The inspector’s decision means those allegations will not now proceed to a full public conclusion through these investigations.

The timeline

Brereton announced in May 2026 that he would resign from the commission. At the time, he said the continuing focus on the investigations was drawing attention away from the NACC’s core mission.

His final day as commissioner was 6 July 2026.

Two days later, on 8 July 2026, Furness discontinued the two complaint investigations.

That sequence matters. The internal scrutiny of the commission’s former head ended after he had already left the role, not while he was still leading the agency.

Reaction and next steps

The NACC said it welcomed Furness’s decision and said it had prevention, education and other investigations continuing.

Acting Commissioner Kylie Kilgour remains in charge while the process to appoint a replacement continues.

For the commission, the practical effect is a shift away from a public showdown over the dropped complaints and toward the broader task of restoring stability after Brereton’s exit.

The episode is still significant because it goes to the NACC’s independence, governance and conflict-of-interest handling. It also raises the question of how much money and effort the oversight system should spend on closed or partly contested complaints once the central issues have been addressed.

Further scrutiny could still come from parliament or political opponents, especially around transparency and the handling of the original complaints. But for now, the inspector’s decision closes the immediate investigations into Brereton.
