This guide provides statistics on the number of boats that have been ‘turned back’ since the practice of removing unauthorised maritime arrivals in Suspected Illegal Entry Vessels (SIEVs) from Australian waters was introduced by the Howard Government (from 2001–2003) and reintroduced by the Abbott Government (in December 2013).

It updates boat ‘turnback’ data provided in another Parliamentary Library publication, Boat arrivals and boat ‘turnbacks’ in Australia since 1976: a quick guide to the statistics (January 2017).
