It seems to me that Australia has returned to its origins as a penal colony, and henceforth no one in their right mind will go there voluntarily. I certainly never will.
Australian government, police and health officials individuals and institutions who imposed and or enforced the COVID tyranny down under should be sanctioned like Iranians or Chinese Communists or Russians.
Travel bans, the freezing of bank accounts and so on.
Turn the screws on them.
