The youth justice system is the set of processes and practices for managing children and young people who have committed, or allegedly committed, an offence. In Australia, it deals primarily with young people aged 10–17 at the time of the offence, although there are some variations among the states and territories. A major component of the system is the supervision of young people in the community or in detention.
