Murderer Terrence John Leary freed on parole - despite stabbing another woman when he was last allowed out of jail

The parole board has released a murderer who stabbed another woman at a bus stop just 10 months after he was last let out into the community. 

The NSW State Parole Authority on Thursday released Terrence John Leary under strict conditions including that he be electronically monitored and reside at a secure Corrective Services-supported facility. 

Fiona Walker, the sister of Vanessa Hoson who was a teenager when she was killed by Leary with a hammer in her home in 1990 after she spurned him, warned in a submission to the board that 'it will happen again'.

When he was last let out on parole in 2012, after serving 22 years for Ms Hoson's murder, Leary took 10 months before he attacked another woman. 

The 30-year-old Thai woman had just finished a babysitting shift in North Sydney on June 19, 2013 and was listening to music at a Hunters Hill bus shelter.

In an 'explosive and ferocious' attack, Leary grabbed her by the neck, pulled her behind the bus stop, punched her in the face, ripped her jeans down so hard her belt snapped and stabbed her in the neck before a passer-by intervened and called police. 

The traumatised woman survived and Leary was sentenced to another 15 years for the assault and attempted rape. 

Ms Hoson's family has tirelessly campaigned against his release over the years and Ms Walker quoted the judge who last sentenced him in her submission, who stated 'he is a continuing danger to society' and 'it cannot be said he has any real prospects of rehabilitation'.

In a media release on Thursday, the State Parole Authority confirmed his release from September 18 and said 'supervised parole is conducive to the safety of the community'. 

Authority Chair, the Honourable Geoffrey Bellew, SC said that if Leary served his full sentence, he would go back into the community unmonitored.

'The alternative is to keep the offender in custody and release him at some later point, either with a shorter period of parole supervision or at the end of his sentence with no period of supervised parole at all.'

'The Community is better served, in terms of its protection, by supervised release.'

Ms Walker argued Leary should be declared a repeat serious sex offender and held on a Continuing Detention Order. 

The Authority confirmed it had considered the expert advice of the Serious Offenders Review Council (SORC) which recommended parole as appropriate.

'The offender has successfully completed programs to address his offending, including a sex offender program,' it said.

In addition to normal parole conditions a number of other rules were imposed including that he must not have any contact with the victim or her family, not go to certain council areas and participate in psychology sessions.
