Effective 6 July 2022, Australia will lift all border restrictions relating to covid-19. This means that people wishing to travel to Australia will no longer need to complete a Digital Passenger Declaration (DPD) to indicate their vaccination status. This will allow all visa holders to travel to Australia and will end the vaccination requirement. As a result, travellers who have not been vaccinated will no longer need to obtain a ‘travel exemption’ prior to departure.
All Australian states and territories have their own requirements for coronavirus measures. Check which rules apply to each state before you travel to Australia.
