Snowtown murders accomplice Mark Ray Haydon, 66, was released on parole in May 2024 to live in the community under strict supervision.

Vlassakis was also a key prosecution witness against John Bunting and Robert Wagner, who were found guilty of 11 and 10 murders respectively.

Both are serving life sentences with no chance of parole.

Vlassakis would be moved to the pre-release centre “provided there is no request to review our decision”, Nelson said.

“There is a 60-day period which would enable either the attorney-general or the commissioner for victims rights or the police commissioner to apply for a review,” she said.

South Australia’s Commissioner for Victims Rights, Sarah Quick, said the decision would “understandably bring fresh pain and anger to those who have already suffered beyond measure”.

“These individuals are not only worn down by their trauma, but also by the ongoing criminal justice processes,” she said.

“The prospect of Mr Vlassakis re-entering the community is a difficult reality for the victims and will require a significant emotional adjustment, adding to an already unbearable burden.

“We must never forget that – for the friends, family and loved ones of murder victims – the impact of the killing does not end simply because a prison term has ended. It is something they live with every day for the rest of their lives.”

A suppression order on images of Vlassakis remains in effect, and there has been a high level of secrecy regarding his imprisonment.
