Youth diversion is for people aged between 10 and 17 years of age and may include a written warning, a conference involving the family, the victim and the offender, of referals to counselling for their behaviour. They may also have to attend drug and alcohol abuse programs to community service programs.

The offenders can only be in diversion programs twice, if they break the law a third time they will have to front the Children’s Court, unless there are exceptional circumstances.
