Latest update:You no longer need to take a COVID-19 test before travelling to the US. However, you must be fully vaccinated against COVID-19 and provide proof of vaccination unless you're a US citizen, permanent resident or qualify for one of the exceptions to this requirement. COVID-19 remains a health risk. Various restrictions and public health measures remain in place and vary by location. Follow the advice of local authorities. Take care to protect yourself from exposure to COVID-19.
The above will change soon, but be careful to check all destination countries.
The decision to amend the Biosecurity Act 2015 to remove these requirements was based on the advice of the Chief Medical Officer.
Travellers must still comply with any remaining COVID-19 requirements of airlines and shipping operators, as well as other countries and states and territories.
This currently includes wearing masks on inbound international flights. State and territory orders mandating masks on domestic flights also remain in place.
