COVID-19 and your visa:
The Department of Home Affairs provides updates to Australia’s immigration and border arrangements during the COVID-19 outbreak here -> https://covid19.homeaffairs.gov.au/
What to do when you can’t get home: Check your visa!
If your visa is due to expire before the border closure is lifted, contact local authorities to arrange an extension. If you don’t know who to contact and how to extend your visa, check the travel advice for the country you’re in, which also has details on our nearest embassy or consulate.
