Section 189 Detention of Unlawful Non-Citizens

Australia’s immigration policy includes mandatory detention for non-citizens found within its migration zone without a valid visa. This policy, which originated in the early 1990s, means that if you are an unlawful non-citizen, detention is not discretionary; it is a legal obligation for immigration officers.  

 

What is the “Migration Zone”? 

The “migration zone” is defined as being “in Australia”. It encompasses: 

  • Australia’s states and territories (land, sea and ports).

  • Australian resources installations (e.g., offshore wind energy facilities, drilling units). 

  • Australian sea installations (e.g., artificial reefs, oil and gas platforms). 

If you are within this zone without Australian citizenship or a valid visa, you are classified as an “unlawful non-citizen”. 

 

Mandatory Detention: Section 189 of the Migration Act 1958 

Section 189 of the Migration Act 1958 grants immigration officers the mandatory power to detain unlawful non-citizens. The use of the word “must detain” leaves no room for discretion, regardless of the individual’s circumstances. This applies to both: 

  • Unauthorised arrivals who enter Australia without a valid visa. 

  • Authorised arrivals who initially enter with a valid visa that later expires or is cancelled. 

Once detained, a person’s release is contingent on either: 

  • The grant of a visa allows them to be released into the community. 

  • Their voluntary departure or removal from Australia
