Teen offenders return to Banksia Hill Banksia Hill is now receiving inmates after recent renovations. TWO dozen young offenders are being moved back to Western Australia's only juvenile detention centre after cells were trashed in a rampage almost eight months ago. On January 20, Banksia Hill's teen detainees staged a riot, trashing 108 of 240 cells. The males were moved to the nearby Hakea Prison for adults, fuelling anger among their parents and concerning Amnesty International, which backed their unsuccessful bid to challenge the legality of the transfer in WA's Supreme Court. The detainees have damaged cells at Hakea on three separate occasions. More than $3 million has been spent on repairs and improved security, and the first of the detainees are in the process being returned to Banksia Hill, the Department of Corrective Services has confirmed. Acting Commissioner for Custodial Services, Heather Harker, said it marked "the start of a new direction and era" in youth detention in the state. She said reforms were being implemented, including more structured daily activities for detainees, which was a key recommendation in a post-riot report by the Inspector of Custodial Services Neil Morgan. Mr Morgan also concluded the riot was "entirely predictable," given the detainees were frustrated with almost constant lock-downs because of chronic understaffing, with many guards on worker's compensation leave. The department said on Wednesday that it expected to have returned all young offenders to the facility within the next few weeks. "It is important to note the return plan remains subject to review and ongoing assessment based on a number of factors, including building works," Ms Harker said. She said the union representing the facility's guards had been consulted about the return plan and infrastructure works at Banksia Hill.
