About 3000 were forcibly returned between June 2020 and June 2021, although the vast majority of those (2,809) are people convicted of a crime. Few non-criminals are forcibly returned to their point of origin once they are in the country, regardless of their immigration status. Three-quarters of people who enter immigration detention after illegally entering the country are released into the population without being returned.
