Does Australia still allow international flights? That's the part of the lockdown thing that I think makes it all useless. If you're still going to allow people to come into your country and have no way of making them isolate for 14days...then its just swatting at flies IMO. Our land border with the USA is closed...but flights still continue. I went to Texas in august and had to isolate for 14 days...I did it..but how many others don't?
australia made isolation compulsory, you had to stay in a hotel room for 14 days and they checked. You did a COVID test the day you landed and again on day 10 and a final one on day 14. This included returning citizens, all of this by the way was 100% at your expense.
