Essentials in Australia

All travelers other than Australian and New Zealand citizens need to present the following documents to officers in immigration clearance: a valid passport or other acceptable travel document, a valid visa or authority to enter Australia (including electronic visas), and a completed and signed Incoming Passenger Card, including health and character declaration. Visas must be obtained in advance of travel. It is not necessary to get a health check-up to travel to Australia, but it is advisable to make sure vaccinations are up-to-date.
