Aboriginal and Torres Strait Islander young people are substantially over-represented in the juvenile justice system in Australia, and this over-representation is highest in the most serious processes and outcomes--particularly in detention. This bulletin examines the numbers and characteristics of Indigenous young people in the juvenile justice system, the types of supervision they experience, recent trends, and associated research findings. Highlights of this report include: (1) Indigenous young people are over-represented in the juvenile justice system, particularly in the most serious processes; (2) They are more likely to experience supervision when aged 10-17; (3) They enter the juvenile justice system at younger ages; (4) They complete shorter periods of supervision, but spend more time under supervision overall; and (5) However, their over-representation in supervision has decreased. Programs and services for Indigenous young people under supervision are appended. (Contains 16 figures and 2 tables.)
