Well, I wish this was true but I'd assume one first has to somehow get onto the Australian Immunisation Registry and then a barcode to proof to the friendly men in black at the front of Opera Bar that one is double vaccinated. Or not?
This in general is what I am still very unclear of. How will they police the vaccinations- just trusting the local checkin agents at point of departure that it has been checked? And then, getting it recognised in Australia surely will take a while, even if your local GP can add this info onto the registry. Unless there's something more simplified in the works but ready in two weeks from now?
So I'd better not hope too desperately for that cold one in my favourite Sydney pub just yet...
