Before you travel to Australia, you should complete the Australia Travel Declaration at least 72 hours before your departure.

The Australia Travel Declaration collects your contact details in Australia, flight details, vaccination information, quarantine requirements and your health status.
This information helps the Australian Government determine your quarantine arrangements (if required) and also allows the relevant health departments to contact you if someone you travelled with tests positive for COVID-19. If you do not complete the declaration you may not be able to board your flight, or you may experience delays when you arrive in Australia.
