The thread title is now so wrong. I rename it to "Only one border must close" .Yes, that's right. We didn't invent the virus here. It arrived by air or sea. Australia is an island, so in the national interests we just now need to bite the bullet and stop all international passenger flights. All of them. No more tourists, no more repatriations, no more incoming pax or transiting aircrew from anywhere, period. I'm appalled that the new highly contagious virulent strain from the UK has now been detected in Australia. Whereas the EU is already stopping UK flights, Australia is wide open. Enough. Don't let them depart or turn them back midair.
