Migration Act 1958 s 196 Australia Compilation: 18 May 2026 Verified: 2026-05-23

Text of provision

(1) An unlawful non-citizen detained under section 189 must be kept in immigration detention until:

(a) he or she is removed from Australia under section 198 or 199; or

(aa) an officer begins to deal with the non-citizen under subsection 198AD(3); or

(b) he or she is deported under section 200; or

(c) he or she is granted a visa.

(2) To avoid doubt, subsection (1) does not prevent the release from immigration detention of a citizen or a lawful non-citizen.

(3) To avoid doubt, subsection (1) prevents the release, even by a court, of an unlawful non-citizen from detention (otherwise than as referred to in paragraph (1)(a), (aa) or (b)) unless the non-citizen has been granted a visa.

(4) Subject to paragraphs (1)(a), (b) and (c), if the person is detained as a result of the cancellation of his or her visa under section 501, 501A, 501B, 501BA or 501F, the detention is to continue unless a court finally determines that the detention is unlawful, or that the person detained is not an unlawful non-citizen.

(4A) Subject to paragraphs (1)(a), (b) and (c), if the person is detained pending his or her deportation under section 200, the detention is to continue unless a court finally determines that the detention is unlawful.

(5) To avoid doubt, subsection (4) or (4A) applies:

(a) whether or not there is a real likelihood of the person detained being removed from Australia under section 198 or 199, or deported under section 200, in the reasonably foreseeable future; and

(b) whether or not a visa decision relating to the person detained is, or may be, unlawful.

(5A) Subsections (4) and (4A) do not affect by implication the continuation of the detention of a person to whom those subsections do not apply.

(6) This section has effect despite any other law.

(7) In this section: visa decision means a decision relating to a visa (including a decision not to grant the visa, to cancel the visa or not to reinstate the visa).

Plain English

Section 196 provides that an unlawful non-citizen detained under s 189 must be kept in immigration detention until they are removed from Australia, deported, or granted a visa. There is no maximum statutory period of detention — a person may be detained indefinitely if removal is not reasonably practicable and no visa is granted. This is the provision that enables what is commonly referred to as indefinite detention.

Practical effect

The High Court upheld the constitutionality of indefinite detention in Al-Kateb v Godwin [2004] HCA 37, finding that s 196 authorised detention even where removal was not achievable in the foreseeable future. This remains one of the most contested aspects of Australian migration law. As of 2023–2024, the High Court revisited this in NZYQ v Minister for Immigration [2023] HCA 37, finding that detention must not continue where there is no real prospect of removal becoming practicable — overruling Al-Kateb. This decision resulted in the release of numerous long-term detainees.
