Two weeks after several convicted child sex offenders walked free from the Yongah Hill Detention Centre — following a High Court ruling — four have finally been fitted with GPS tracking devices. WA Police Commissioner Col Blanch has revealed four of the most high-risk foreign criminals released — known as reportable offenders — were fitted with ankle bracelets after being released on November 11. Four other convicted child sex offenders, also released from Yongah Hill a fortnight ago, have since left WA. “The four reportable offenders, who have been found guilty of child sex offenders, now have ankle bracelets as of yesterday (Friday),” Commissioner Blanch said. But WA’s top conceded he had no idea how many detainees in total had been released into the WA community, as he confirmed another two detainees from Yongah Hill were released on Thursday night. “It changes every day,” Mr Blanch said. “They release two or three every day. They released two last night. “I can’t give you an exact number of (former detainees now out in the community) because they are leaving WA at quite a rate. “Many are not, in fact, West Australians and have chosen not to stay.” About 30 detainees walked free from Yongah Hill Detention Centre on November 11 — with a dozen detainees ending up at a Thornlie motel before finding their own accommodation. Following a public outcry over their release when the High Court ruled indefinite detention was unconstitutional, the Federal Parliament passed new laws which allowed Australian Border Force to fit the most dangerous criminals — murderers, rapists and child sex offenders — with GPs ankle bracelets. But in the last fortnight, neither Federal nor State authorities have been able to confirm how many bracelets have been fitted. Commissioner Blanch said the Australian Border Force had allocated 11 bracelets for detainees released into the WA community, including the four who have had them fitted. “They (border force) are in the process of fitting them (on detainees),” Commissioner Blanch said. Border Force monitors any detainee fitted with an ankle bracelet via the NSW Department of Corrections. But if they are child sex offenders, they are also monitored by WA police under the Community Protection (Offender Reporting) Act. Under the Act, reportable offenders need to keep police informed of where they live and other personal details such as where they work, affiliation with clubs and the make, model, colour and registration of their car. “Four reportable offenders not only have an ankle monitor, but I know our central offender management squad are putting everything they can into this to make sure these people are under stringent supervision and are being watched at all times,” Mr Blanch said. “They are the most highly scrutinised and highly monitored released sex offenders in the state. “They can live at a place of their choosing as long as we assess it to ensure it’s not near a school or children. “We monitor where they live; they must report what they drive, their electronic devices, and who they live with.” A lack of information regarding exactly what number of detainees have been released into WA or what crimes they have committed has frustrated not just concerned members of the public but leaders such as WA Premier Roger Cook, who last week expressed his frustrations. “This has been frustrating for our community,” Mr Cook told The Sunday Times. “Community safety is a major priority, which is why officers from WA Police are taking proactive measures to do everything they can to keep Western Australians safe.” Asked on Saturday whether he was disappointed at the High Court ruling, Commissioner Blanch said: “My job is community safety. “Anything that threatens community safety will always be a concern of mine. “Having said that, we have 4000 reportable (sex) offenders (in WA). “So we are continually monitoring those people, putting them under a regime of strict supervision. “Our job is one of priority. And we ensure that if a high priority and a high risk are out there, police are in it, and we are protecting the community.” WA Liberal leader Libby Mettam said there had been an “appalling lack of collaboration between the state and federal Labor Governments over the release of these offenders from Yongah Hill. “After two weeks of passing the buck it’s of some relief that these GPS devices have now been fitted to 4 of the child sex offenders, but there remains outstanding concern about the lax approach to those who govt can’t account for,” Ms Mettam said.
