Paul Brereton – the outgoing head of Australia’s National Anti-Corruption Commission – was grilled at Senate estimates this week.

Brereton’s time leading the body charged with investigating serious corruption in the Commonwealth public sector has ended in a crisis of confidence – over Robodebt, his ongoing Defence links, and whether the watchdog properly managed conflicts of interest.

Today, independent journalist Nick Feik, on how Australia’s anti-corruption watchdog ended up in crisis – and whether it can recover.
