Some states in Australia are experiencing small (by
international standards) Covid-19 outbreaks. The state governments
in Australia have primary control over the health system, so some
states have closed their borders to people entering from other
states.
All international travellers planning a trip to Australia in the
next 4 weeks should arrive into the capital city of the state they
intend to spend the majority of their time in Australia in.
Arriving in a state other than the final destination may result in
2 weeks quarantine at the international arrival point and then a
further 2 weeks quarantine (and border exemption application) in
the state they intend to spend time in.
