Breakdowns

What this measures

The number of entries into immigration detention in a 12-month period. Each entry is an occurrence, so a person detained twice is counted twice.

What this doesn’t measure

The number of distinct people detained, people held in prisons under immigration powers before 2017, or how long people were detained.

Important caveat

Entering and leaving detention count occurrences, not individuals: a person detained twice in a period is counted twice. People in detention is the number held on the last day of the period. People held in prisons under immigration powers are included only from 2017. Data from 2026 Q1 onwards is provisional and will be revised in a future publication.

Revision history

No period of this series has been revised since it was first ingested here. Revisions are recorded automatically when a later release publishes a different figure for the same period.
