The page explains what it holds and what it leaves out. Most detention tables published as part of the Immigration system statistics release contain a time series, so they are not available on this page. Previous tables are available here if they contain data that would otherwise be lost when a new release is published, for example tables without a time series.
Summary tables published before June 2023 are not listed on this page. For those, the page refers readers to previous editions of the Immigration system statistics quarterly release.
The page links to two related items: Immigration system statistics data tables and Immigration system statistics quarterly release.
