The man sentenced to die in prison for killing Sarah Cafferkey and dumping her body in a bin is appealing over his life without parole sentence.
Steven James Hunter, 47, was told he would never be released when he was sentenced to go to jail for the stabbing-death of Ms Cafferkey at his Bacchus Marsh home on November 10 last year.
On Thursday, the Victorian Court of Appeal will hear an application for leave to appeal against that sentence.
The two-time killer pleaded guilty to the crime, committed 11 days after his parole ended for kidnapping and assaulting a man.
Hunter told police upon his arrest he should be locked up until he dies, though his lawyer Tim Marsh later argued he should be spared life without parole.
In September, Mr Marsh lodged an appeal with the Victorian Court of Appeal.
He first killed in 1986 when he stabbed work colleague Jacqueline Mathews for rejecting his sexual advances.
He was jailed for 16 years for her murder in 1988. He has also been convicted of a list of other offences, including assault, escaping jail and kidnapping.
In sentencing Hunter to prison with no opportunity for parole, Supreme Court Justice Kevin Bell said the murder fell into the worst category of the worst offence in the criminal calendar.
