1. Key facts
The number of people entering detention in the year ending September 2015 increased by 11% to 32,741 from 29,491 in the previous year. Over the same period there was an 11% increase in those leaving detention (from 29,161 to 32,481).
There was a continuing decline in the proportion of detainees being removed on leaving detention from the most recent peak in the year ending March 2011 of 64% to 47% in the year ending September 2015. The decline in the last quarter, July to September 2015, may be attributed to the cessation of the detained fast track process in July 2015. Conversely, there was an increase in the proportion of detainees granted temporary admission or release, from 28% to 42%, and an increase in the proportion of detainees granted bail, from 6% to 10%, over the same periods.
As at the end of September 2015, 3,531 people were in detention, 5% higher than the number recorded at the end of September 2014 (3,378).
In the third quarter of 2015, 31 children entered detention and 31 children left. There were 2 children in detention as at 30 September 2015.
