Victoria's coroner has flagged recommending post-parole supervision orders for violent offenders, like those for sex offenders who pose an ongoing public risk.
Coroner Ian Gray is investigating Steven James Hunter's murder of 22-year-old Sarah Cafferkey in 2012, 11 days after Hunter finished parole for other crimes.
Hunter, now 49, is serving life in prison for fatally stabbing and bashing Ms Cafferkey before dumping her body in a wheelie bin and pouring concrete on it.
Judge Gray asked Corrections Victoria deputy commissioner of operations, Roderick Wise, if there was merit in supervision orders for serious violent offenders like Hunter, who could end parole while still posing an unacceptable risk due to unresolved issues.
Mr Wise said such a policy had been contemplated for some time.

"It has got some merits, but would be a very difficult scheme to administer," he said.
Most offenders end parole with unmet needs, and it would be hard to determine a threshold for imposing a further supervision order, he said.
Mr Wise said monitoring of parolees had been beefed up since 2012, with all serious violent and sexual offenders required to attend regular case management review meetings overseen by more senior officers.
Judge Gray was told the parole board now had a full-time chair and more community-representative members, allowing it to sit for more days.
"The board now sits each day of the week and there will be multiple boards sitting," said Stuart Ward, chief administrative officer of the Adult Parole Board.
Mr Ward said this allowed more time for each case, with fewer successful parole applications and parole cancellations for a breach.
Judge Gray is investigating Hunter's parole and transition to non-parole, and outcomes of the police investigation into the disposal of Ms Cafferkey's body.
Hunter, who was convicted for another murder in 1988, said he acted alone, but police also investigated some of his associates.
Mr Ward was the inquest's final witness and the coroner will deliver his finding at a date to be fixed.
