A Sydney child murderer and rapist, who was released in June after more than 26 years behind bars, will be subjected to strict conditions in the community for the next five years.
Justice Michael Walton on Friday allowed the NSW government's application for a five-year extended supervision order for Phillip Wayne Lett.
The 58-year-old believed his crimes were so terrible he never applied for parole.
Lett was released from jail on June 23 under a NSW Supreme Court interim supervision order, after serving his total sentence of 26 years and six months.
Three days before Christmas in 1992, he murdered a six-year-old boy who had been playing in a park in Penrith near his home.
Lett was sexually motivated when he offered him a ride and drove him to a railway station car park, where he was found dead the next morning.
The boy was naked, apart from wearing shoes, and his underpants were tied around his neck and on top of them his board shorts were knotted and tied around his neck.
He had been punched, strangled and thrown out the car window before Lett drove over his limp body multiple times.
Lett was later convicted of raping another young boy fortnightly between 1988 and 1992.
Justice Walton found Lett was "highly vulnerable to dynamic risk factors" especially because of his institutionalisation.
Risks were elevated because of the high degree of probability Lett will find it difficult to cope with the stress of returning to the community.
"The defendant committed the serious violence offence and serious sex offences when he was abusing illicit drugs and alcohol, was feeling lonely, his mental health declined and he was unable to control his emotions," the judge said.
"Supervision will, in my view, reduce the risk of reoffending and both protect the community and encourage rehabilitation.
"The circumstances of the defendant's offending and the possible drastic consequences of the same warrant orders for the safety of the community."
