Reasons for detention
The graphs on this page show the proportion of people in detention according to the reason for their detention.
The first graph shows the numbers of people in detention over time by the reason of detention: visa cancellation for character reasons (under section 501 of the Migration Act), because they were seeking asylum by boat, or other reasons.
The second graph shows the numbers of people in each detention facility by the reason they were detained (Note: this does not include people in APODs).

This graph shows the numbers of people in detention who had a previous refugee or protection visa or claims.
This graph shows the numbers of those in held detention who previously held refugee or humanitarian visas, by the visa they previously held.
