The girlfriend of fired Border Force Commissioner Roman Quaedvlieg's had her letter of resignation accepted on Thursday, more than two months after sending it.
Quaedvlieg, 53, was found to have secured Sarah Rogers, believed to be in her 20s, a job in December 2016 just months after they started a relationship.
Ms Rogers worked as a passport scanner for the Australian Border Force at Sydney Airport and was understood to have pre-empted her own dismissal.
She submitted her resignation after receiving a letter requesting she defend why she should be allowed to keep her job, Weekend Australian reported.

Quaedvlieg was dismissed following a 10-month investigation by the Australian Commission for Law Enforcement Integrity and the secretary of the Department of Prime Minister and Cabinet, Martin Parkinson, on Thursday.
The investigation found him guilty of misleading Immigration Minister Peter Dutton about the status of his relationship with Ms Rogers and changing internal ABF policies to secure her a position.
The 53-year-old denied the allegations and said his relationship with the much younger woman only started after she got the job in December 2016.
He also hit back at accusations he used a work phone to send 14,000 texts across the span of a year, denying all allegations of misconduct.
