Prisoners on life sentences in relation to murder who refuse to reveal the location of bodies will be denied parole under new reforms passed by the South Australian Government.

Those who do achieve parole will be subjected to parole conditions for the rest of their lives, with the Parole Board "compelled" to consider electronic monitoring, including via GPS.

SA Correctional Services Minister Tony Piccolo said the changes provided a fairer process and better supported victims' families, especially those in murder cases where a body had not been found.

"If the body is not located, or in the case where there are known associates to that crime, if the prisoner does not cooperate with police to either help identify the location of the body, or the associates, they'll be ineligible for parole," he said.

"These laws are much tougher and that's designed clearly to support the families of the victims of crime, to help them get closure."

The reforms have also removed the Government's ability to veto parole board decisions on murderers and will create a new body to review parole decisions.

It marks a departure from Government intervention in judicial decisions, which became a hallmark of former premier Mike Rann and treasurer Kevin Foley in an era when the Government wielded a tough arm on law and order.

Mr Piccolo said removing political interference from the parole process was important.

"It's important that the process is seen to be fair. This process is transparent. It's fairer, and importantly [it's] certainly not a weakening of the law," he said.

The reforms passed the Legislative Council unamended and are expected to come into effect later this year.
