Roman Quaedvlieg's rise and fall

THE RISE AND FALL OF ROMAN QUAEDVLIEG

* Appointed as the first Border Force commissioner in 2015

* Investigation begins in May 2017 over allegations he helped a junior staffer, with whom he had a relationship, secure work at Sydney Airport.

* Goes on paid leave while the investigation is underway, earning roughly $500,000 while off work.

* His conduct was the subject of two confidential reports, one from the corruption watchdog and one from the head of the prime minister's department.

* Quaedvlieg consistently denied allegations made against him.

WHAT THE INVESTIGATION FOUND

* He modified policies to advantage a particular candidate for Border Force employment, reportedly his girlfriend.

* He made a false statement to now-Home Affairs Minister Peter Dutton about his personal relationships, and failed to disclose a significant change in his personal life.

* The relevant conduct went beyond an isolated error of judgment and ultimately undermined his capacity to continue in his role.

* He engaged in acts of misbehaviour and conduct inconsistent with his affirmation.
