Australians have also been told to reconsider their need to travel, an upgrade from previous advice recommending against non-essential travel.
An update to the Smart Traveller website on Tuesday night warned that Australians overseas should make plans to return as soon as possible, due to border closures across the world.

"Consider whether you have access to health care and support systems if you get sick while overseas. If you decide to return to Australia, do so as soon as possible. Commercial options may become less available."
