"Of the 5,513 young people under youth justice supervision on an average day in 2017–18, most were male (81%) and supervised in the community (83%). Overall rates of supervision varied among the states and territories, from 12 per 10,000 in Victoria to 59 per 10,000 in the Northern Territory. Supervision fell over the 5 years from 2013–14 to 2017–18 for community-based supervision, but rose for detention. Indigenous over-representation also continued to rise."
