Convicted murderers in NSW are one step closer to losing hope of early release as the state government introduces new "no body, no parole" laws.
The laws are aimed at coaxing murderers into giving up the final resting place of their victims if they want to be released on parole.
Corrections Minister Geoff Lee introduced the proposed "Lyn's law" to parliament's lower house on Wednesday, which will need to pass both the lower and upper houses before becoming law.
The name refers to Lynette Dawson, the Sydney mother who was murdered by her husband Chris Dawson in 1982 as he pursued an affair with one of his high school students.
"This bill would help the families and friends get the closure that they deserve," Mr Lee told parliament on Wednesday.
"The bill gives victims dignity and respect."
Parole boards already consider whether killers have revealed the locations of victims' remains but the proposed laws would make it tougher.
Police would have to indicate to the parole board the timeliness and usefulness of the information provided.
Mr Lee said co-operation would be a prerequisite for parole but it would not mean automatic release, community safety and other considerations would also be reviewed.
"The law would also not allow any leniency if the offender does not enter co-operation," Mr Lee said.
Opposition corrections spokeswoman Tara Moriarty has said Labor needed to see the detail of the legislation but would support it, saying the change was long overdue.
Dawson was convicted last month of murdering Ms Dawson.
The body of the mother of two has never been found and her case sparked calls for the proposed changes.
