The Department of Juvenile Justice (DJJ) manages young offenders by means of supervision within the community or within Juvenile Justice Centres under remand or control (sentenced) orders. Under the Children's (Criminal Proceedings) Act 1987 and associated legislation, young offenders are defined as aged between 10 and 18 years. Depending on the security and risk level of a detainee, offenders can be transferred into the adult correctional system when they turn 18 years of age, though in special circumstances older offenders may remain in the care of DJJ.
