The head of the Australian Border Force Roman Quaedvlieg will have his future decided by Attorney-General Christian Porter.

Quaedvlieg took leave in May last year with an investigation probing a Border Force job given to his girlfriend at Sydney Airport. In Senate estimates hearings yesterday it was confirmed he has since been paid $500,000 to not come to work. Quaedvlieg told The Australian yesterday ($) the length of the investigation had been "extraordinary" and confirmed he would return to the role.
