The right of return to your own country is a basic human right and Australia should be obliged to accept any citizen who wants to enter even if it means emergency quarantine facilities run by the army need to be provided.
International law states no country will deny its citizens entry at the border. If we can get home, they have to let us in.
Quite right. A country cannot refuse entry of it's own citizens. However our best and brightest are circumventing this requirement by placing caps on passenger numbers on flights, this may be legal. So if you arrive at the border of Australia you will be processed into the country and not turned away. Private yacht, aircraft, drift in by way of a refugee style boat and you will allowed entry (then quarantine). A neat legal work around brought to you by our elected reps. Of course foreign nationals who play tennis...come on in.
