Youth justice in Australia 2022–23

This fact sheet summarises key findings of young people under youth justice supervision for Tasmania, including the number and rate of young people under community-based supervision and in detention. It also summarises data on young people by age, sex, Indigenous status, legal status, time under supervision and contains trends. 

Number and rate 

On an average day in 2022–23, in Tasmania:

• 109 young people aged 10 and over were under youth justice supervision (Table S136a)
• almost 9 in 10 (88%) were supervised in the community (Table S136b), and the rest (13%) in detention (Table S136c) (proportions might not sum to 100%, as young people may be under community-based supervision and in detention on the same day)
• the rate of supervision was 15 per 10,000 young people aged 10–17 (Table S137a)
• 12 per 10,000 young people aged 10–17 were under community-based supervision (Table S137b), and 2.4 per 10,000 were in detention (Table S137c).

Age and sex

On an average day in 2022–23, in Tasmania:

• 73% of those under supervision were aged 10–17, and the rest were 18 and over
• 71% of those under supervision were male
• males under supervision were most likely to be aged 17, while females were most likely to be aged 16 (Table S136a).

Number of young people under supervision (any type) on an average day, by age, sex and Indigenous status, Tasmania, 2022–23

Notes: 

1. Age categories are not presented where they represent averages that are equal to or rounded to 0.0. 
2. Total includes young people of unknown age, sex and Indigenous status. 
3. Number of young people under community-based supervision and in detention may not sum to total number under supervision as young people may be under community-based supervision and in detention on the same day and may be in different age groups. 
4. Age on an average day is calculated based on the age a young person is each day that they are under supervision. If a young person changes age during a period of supervision, then the average daily number under supervision will reflect this. Average daily data broken down by age will not be comparable to Youth justice in Australia releases prior to 2019–20. 
5. The equivalent 'during the year' table or unique counts of young people is not published due to small numbers, confidentiality, and/or reliability concerns.

First Nations young people

On an average day in 2022–23, in Tasmania:

• First Nations young people made up 10% of those aged 10–17 in the general population, but 31% (or 24) of those of the same age under supervision (tables S136a and S143)
• a similar proportion of First Nations young people aged 10–17 were under community-based supervision (31% or 21) and detention (30% or 3.9) (tables S136b and S136c)
• First Nations young people aged 10–17 were about 4 times as likely as non-Indigenous young people to be under supervision (46 per 10,000 compared with 11 per 10,000) (Table S137a)
• First Nations over-representation was similar in community-based supervision and detention (about 4 times the non-Indigenous rate) (Table S137b).

Time under supervision

In 2022–23, in Tasmania:

• completed periods of supervision lasted a median length of 181 days (about 26 weeks) (Table S29)
• when all time spent under supervision during the year is considered, young people spent an average of 199 days (about 28 weeks) under supervision (Table S30).

Sentenced and unsentenced detention

On an average day in 2022–23, in Tasmania:

• 86% of young people in detention were unsentenced—that is, they were awaiting the outcome of their court matter, or had been found guilty and were awaiting sentencing
• about 1 in 4 (24%) young people in detention were serving a sentence (proportions might not sum to 100% because some young people were in sentenced and unsentenced detention on the same day) (Table S108a).

Trends to 2022–23

Over the 5 years to 2022–23, on an average day in Tasmania:

• the number of young people under supervision fell overall from 155 to 109 (Table S136a). The rate decreased overall from 23 to 15 per 10,000 young people aged 10–17 (Table S12a)
• in community-based supervision, the number fell overall from 144 to 95 (Table S136b). The rate decreased from 21 to 12 per 10,000 (Table S45a)
• in detention, the number fluctuated between 9.1 and 16 (Table S136c), as did the rate (between 1.5 to 2.7 per 10,000 (Table S83a).

Notes: 

1. Total includes young people of unknown age, sex and Indigenous status. 
2. Number of young people under community-based supervision and in detention may not sum to total number under supervision as young people may be under community-based supervision and in detention on the same day and may be in different age groups. 
3. Age on an average day is calculated based on the age a young person is each day that they are under supervision. If a young person changes age during a period of supervision, then the average daily number under supervision will reflect this. Average daily data broken down by age will not be comparable to Youth justice in Australia releases prior to 2019–20. 
4. The equivalent 'during the year' table or unique counts of young people is not published due to due to small numbers, confidentiality, and/or reliability concerns. 
5. Rates are number of young people per 10,000 relevant population.
