Australia: Do I need a visa to enter?
Everyone who enters Australia must have a valid passport or other acceptable travel document. Citizens and residents of all countries (besides New Zealand) must apply for a visa prior to entering Australia. Once you have obtained a visa and have entered Australia, you may apply to extend your visa for up to an additional six months if necessary.
Citizens of New Zealand who have New Zealand passports may enter Australia by presenting their passports and completed Incoming Passenger Cards. They will be issued a Special Category Visa (SCV) upon entry into the country.
Military personnel from certain designated countries, along with their partners and their dependents may enter Australia without a visa by presenting their military ID cards and Movement Orders along with valid passports and completed Incoming Passenger Cards to border officials.
