Everyone travelling to Australia must present a valid and approved travel document as evidence of their identity and nationality. The most common and preferred travel document is a passport, but other types of travel documents may also be accepted.

Australian citizens have an automatic right of entry to Australia, and do not require a visa. Australian citizens need only to present the following documents to officers in immigration clearance: * a valid Australian passport or other acceptable travel document * a completed and signed Incoming Passenger Card. Australians who hold dual or multiple nationalities should hold an Australian passport and use it to enter or leave Australia, even when using a foreign passport overseas. The only exception is where they have been issued with an Australian Declaratory Visa.
