Australians entering and leaving Australia:
All Australians, including dual nationals, must enter and exit Australia on their Australian passport.
Those with dual nationality should review the entry and exit requirements for travel to and from the country of their other nationality. This may mean there is a requirement for you to travel with more than one passport.
International airlines have an obligation to carry only appropriately documented passengers to Australia. Those who are unable to produce the required documentation at check-in may be delayed or refused boarding. Appropriate documentation for Australian nationals, including those with dual nationality, is an Australian passport. Appropriate documentation for a foreign national is a visa to enter Australia. Australian citizens do not qualify for a visa in a foreign passport for entry to Australia.
See the Department of Home Affairs website for further information on citizenship and travel.
Australian/British or Australian/Irish dual nationals entering and leaving the United Kingdom:
Australian-British or Australian-Irish dual citizens must enter the UK on their British or Irish passports, or through a certificate of entitlement in another valid passport. These dual citizens are unable to obtain an ETA or visa to enter the UK. Dual citizens may not be able to board a flight to the UK without a valid document.
