Events in “international politics” show the vital importance of an effective National Anti-Corruption Commission, experts say.

The National Anti-Corruption Commission is protecting the public officials most culpable over the $1.7 billion unlawful Robodebt scheme, citing “personal privacy”.

The National Anti-Corruption Commission Inspector has announced she will investigate the regulator’s refusal to investigate over Robodebt.

Claims by National Anti-Corruption Commission boss Paul Brereton that he “recused” himself from the Robodebt referrals have “no justification whatsoever” and are “simply wrong", says top former judge.

The sole person responsible for policing internal corruption at the National Anti-Corruption Commission is refusing to say whether an actual “investigation” has begun into the Robodebt referrals scandal.

National Anti-Corruption Commission boss Paul Brereton made misleading statements to Attorney-General Mark Dreyfus over his management of conflicts of interest over Robodebt.
