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

Multi-billionaire Steven Lowy — who directed $550,000 in secretive payments to the Liberal Party weeks before the last federal election — says the nation is suffering a “slide in values”.

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.

The conflicts at the top of the National Anti-Corruption Commission over Robodebt extend beyond boss Paul Brereton – but the agency is hiding the documents.

The National Anti-Corruption Commission has scrubbed from official freedom of information documents the name of its deputy leader who made the “decision” to not investigate over Robodebt.
