Marise Payne on Friday said Mr Palfreeman, who was released in October after serving nearly 12 years behind bars in Sofia for murder, has everything he needs from Australia to leave the Balkan nation.

However the 33-year-old says he remains unable to leave the country as his movement is restricted by the Bulgarian government over issues relating to an expired travel ban.

"We're at the final end of those processes and we've been very clear with the government in Bulgaria that we expect to see Mr Palfreeman able to travel as soon as possible," Ms Payne told AAP in Sydney on Friday.

"Once that travel ban is lifted then that should be readily facilitated.

"He has everything he needs from the Australian side to do that ... and then he'll be able to make his own decisions about where to next."

Ms Payne said Australian government officials would continue to engage with their Bulgarian counterparts to ensure there were no further impediments to Mr Palfreeman's freedom of movement.

Bulgaria's interior ministry in May told reporters it would start the process of lifting the travel ban after a bid to appeal Mr Palfreeman's parole was thrown out of the Supreme Court of Cassation.

But the former Riverview student told AAP at the time that the "illegal refusal" to let him leave the country hadn't halted.

Mr Palfreeman was found guilty of murder and attempted murder for stabbing two Bulgarian youths during a street melee in 2007. He has always maintained he acted in self-defence.

Hristo Monov, the father of the man killed by Mr Palfreeman, earlier this month said the Australian's early release was illegal and that the three-judge panel who made the decision in September were corrupt.

"I just want (Palfreeman) to go back to prison for one more night - they'll be so happy to see him," Mr Monov, a former Bulgarian Socialist Party MP, told reporters in Sofia.
