No vaccine what happens ?, page-132

What do you think Plan B should be then?

Say you are right and Aus has to stay effectively isolated for years. What does that actually mean? No Tourists or international students? Business can all be done remotely, we've learned that now. Goods get in and out just fine. Those who really need to travel can, but they need to go into supervised isolation.
So.. where is the biggest problem? Eradicate and lose international students and tourists. What else will be affected? I'm not being a smarty, I actually want to know.
