Yet nationally in that 10-17 year age group, Indigenous youth make up only six per cent of the population.

More figures showing Aboriginal or Torres Strait Islander youth are over-represented in youth prisons or under corrections orders were released today.

Again, the Northern Territory in percentage terms has the highest number of youth in prison.

In the NT, most young people in forced supervision are both Indigenous and male.

Of the 5694 young people under youth justice supervision on an average day in 2018-19, most were male (80%) and supervised in the community (84%).

Overall rates of supervision varied among the states and territories, from 11 per 10,000 in Victoria to 61 per 10,000 in the Northern Territory.

The rate of Indigenous people under youth justice supervision has fallen over the past five years, a report from the Australian Institute of Health and Welfare has shown.

The report, Youth justice in Australia 2018-19, presents information on young people aged between 10 and 17 years under youth justice supervision both in the community and in detention.

Over the 5 years to 2018-19, the number of young people aged 10 and over who were under supervision on an average day fell from 186 in 2014-15 to 171 in 2017-18, rising back to 187 in 2018-19. The rate for those aged 10-17 fluctuated with an overall increase from 58 to 61 per 10,000.

On an average day in 2018-19, there were 5694 (1 in 490) young people under youth justice supervision due to their involvement, or alleged involvement, in crime. Throughout the year, a total of 10,820 young people were under supervision.

In 2018-19, the most common principal offences among young people aged 10-17 were:

"Between 2014-15 and 2018-19, the level of Indigenous over-representation in youth justice supervision stabilised," AIHW spokeswoman Anna Ritson said.

"The rate of Indigenous young people aged 10-17 under supervision on an average day fell from 176 to 172 per 10,000. The rate of non-Indigenous young people fell from 12 to 11 per 10,000.

"Although only about 6% of young people aged 10-17 in Australia are Aboriginal or Torres Strait Islander, half (2,448) of the young people under supervision on an average day in 2018-19 were Indigenous."

Indigenous young people aged 10-17 were 16 times as likely to be under supervision as non-Indigenous young people in 2018-19.

The report also shows that, on an average day in 2018-19, young males were about 4 times as likely to be under youth justice supervision as young females.

Young females under supervision were more likely to be younger than males, with the most common age being 16 for young females and 17 for young males.

"Being under youth justice supervision doesn't always mean a young person is in detention. Around four in five young people (4,767) received community-based supervision such as home detention, bail, parole and probation," Ms Ritson said.

"The remaining 1 in 5 (956) were in detention, most of whom were remanded in custody awaiting the outcome of their charges."
