The Transit visa (subclass 771) is an Australian visa that allows a traveller to be in Australia for up to 72 hours while transiting to another destination — typically at a major Australian international airport. Whether a particular traveller needs a transit visa depends on their nationality, travel documents, and the nature of their transit. Some nationalities are eligible to transit without a visa (TWOV) if they hold certain onward documents; others require the subclass 771 before arrival in Australia. Travellers who need to clear Australian immigration — whether because of their itinerary, baggage collection, or an overnight connection — generally need either the Transit visa, a substantive visa (visitor, student, etc.), or to be TWOV-eligible. One important legal feature of the 771 is that its holders cannot apply for other Australian visas while in Australia — it is not a substantive visa for the purposes of bridging visa entitlements. This page explains who needs a transit visa, the TWOV eligibility, the 72-hour limit, the restriction on lodging other applications, and the distinction between airside transit and immigration clearance transit.

• Migration Regulations 1994, Schedule 2, Subclass 771 (Transit) criteria — the eligibility criteria for the transit visa; the holder must be in transit to another country, must have a confirmed onward itinerary, and must depart within 72 hours; the conditions on the 771 restrict the holder to transit activities
• Migration Regulations 1994, regulation 2.20 — bridging visa entitlements — the subclass 771 Transit visa is not listed as a "substantive visa" from which a bridging visa application is automatically triggered; holders of a 771 who lodge a visa application do not receive a Bridging Visa A in the same way as holders of substantive visas; this is a critical distinction affecting any person who finds themselves in Australia on a 771 and considers lodging a further application
• Migration Regulations 1994 — Schedule 2, criteria excluding applications from 771 holders — certain visa criteria (including the onshore partner visa 820) require that the applicant hold a substantive visa other than the 771; the 771 is specifically excluded as a qualifying base visa for onshore applications

Who needs a transit visa

Whether a traveller requires a subclass 771 Transit visa to transit through Australia depends on:

• Nationality: nationals of some countries can enter Australia without a visa and therefore transit without a transit visa (using their ETA or eVisitor instead, if applicable, or under a visa exemption); nationals of other countries require a visa to enter Australia — if they are transiting, the transit visa is the appropriate product if they cannot use a visitor visa
• TWOV eligibility: some nationalities are eligible to transit through Australia airside without any Australian visa — this is the Transit Without Visa (TWOV) arrangement; DHA publishes the list of TWOV-eligible nationalities and the conditions (such as holding a valid visa for the destination country and having a through-ticket)
• Nature of the transit: whether the traveller clears Australian immigration (passes through the immigration barrier) or remains in the international airside area affects whether a visa is needed

Transit Without Visa (TWOV)

The TWOV arrangement allows eligible travellers to transit through Australian airports without holding an Australian visa:

• TWOV is only available to nationals of specific countries listed by DHA — the list is maintained on the DHA TWOV page and reflects bilateral arrangements
• To be eligible for TWOV, the traveller typically must hold a valid visa for their onward destination, have a confirmed through-ticket departing within 8 hours of arrival, and not require clearing Australian immigration (i.e., remain airside)
• Even TWOV-eligible travellers must obtain a transit visa if they need to clear Australian immigration — for example, to collect checked baggage that cannot be through-checked, or if the airport does not offer airside transit facilities for that routing

For the current list of TWOV-eligible nationalities and conditions, refer to the DHA TWOV page.

The 72-hour limit

The subclass 771 Transit visa permits the holder to be in Australia for a maximum of 72 hours from the time of arrival. This 72-hour period is the visa duration — it is not an advisory or a normal transit window but the legally permitted period of stay. The holder must:

• Depart Australia within 72 hours of arrival
• Depart on a confirmed onward journey to a specific destination outside Australia
• Not seek to remain in Australia beyond the transit period

Remaining in Australia beyond the 72-hour transit visa period causes the holder to become an unlawful non-citizen — subject to the enforcement provisions of the Migration Act.

Cannot apply for other visas while on a 771 — a critical restriction

The subclass 771 Transit visa has an important legal characteristic that distinguishes it from substantive visas: holders of a 771 cannot lodge most other Australian visa applications from within Australia. This arises because:

• The Migration Regulations criteria for many onshore visa applications (including the partner visa subclass 820, student visa, and others) require the applicant to be the holder of a substantive visa other than a subclass 771 at the time of application
• The 771 is not classified as a substantive visa for the purpose of bridging visa entitlements — a person who lodges a visa application while on a 771 does not receive a Bridging Visa A in the normal way; this means they cannot remain lawfully in Australia while that application is processed after the 72-hour period expires

The practical consequence is that a person who is in Australia on a 771 (even for a legitimate transit reason) cannot use that time to lodge a substantive visa application and remain lawfully in Australia. This is in contrast to someone in Australia on a visitor visa 600, who can lodge certain applications and receive a BVA.

Transit facilities at Australian airports

DHA maintains information on transit facilities at major Australian airports (Sydney, Melbourne, Brisbane, Perth, Adelaide) on the DHA website. Transit facilities vary by airport and affect whether airside transit (without clearing immigration) is possible for particular routings. For the current state of transit facilities, refer to the DHA transit facilities page.

The transit visa is one of the most misunderstood visa categories in the Australian system — the 72-hour limit and the restriction on lodging other applications are not well known among travellers who encounter unexpected itinerary issues at Australian airports. The prohibition on applying for other visas from within Australia while on a 771 is particularly important for migration practitioners — a client who arrives in Australia on a transit visa and then seeks to remain (because of changed circumstances, a family emergency, or a change of mind) is in a much more constrained legal position than someone who arrived on a visitor visa. The only pathway in that situation is to seek an urgent alternative visa through ImmiAccount before the 72-hour period expires, or to accept departure and apply offshore.
