The Albanese Government is refusing to disclose key findings of a corruption probe into the corporate regulator that were secretly deleted under former Treasurer Josh Frydenberg.

Former Federal Treasurer Josh Frydenberg has said he was considering a political comeback – despite revelations he covered-up a corruption scandal at the nation’s corporate regulator.

Department of Finance Secretary Rosemary Huxtable wasn’t the “decision maker” who approved the department’s waiving of a $41,000 debt to a senior public official, her department has claimed.

The Federal Government was warned waiving senior official’s $41,000 debt was likely illegal and the opposite of the “many examples” of recovering “Centrelink overpayments”. It fully waived the debt anyway.

The Federal Government has become embroiled in another salary cap scandal, this time involving a key official of the nation’s media watchdog, secret Ombudsman documents reveal.

The corporate regulator has completed its review into the expenses scandal that cost the jobs of its chair James Shipton and deputy Dan Crennan - but it’s refusing to disclose the outcome.
