The plan is not to stop the disease here , it's to make everyone get the jab so we can live with it . Quarantine is not the answer , we have to mingle with the rest of the world .
As much as I'd like to build a wall around Australia and send all the naughty people to Tassie .
Plans can fail easily.
As a hypothetical, what if the current vaccines do not work with a new strain that evolves? This is highly possible if the rest of the world does not vaccinate at the same time. Realistically we are going to have a lot of large developing countries that are not going to get the majority vaccinated and at the same time be a breeding ground for new strains that emerge.
Right now, we need to be able repatriate people from countries where Covid is a major problem. These are Australian citizens so we can't just sit on our hands and tell them bad luck. In order to repatriate them we need facilities that get them through the incubation period without passing it onto the staff or other residents. Its no use going 13 days into isolation, letting them catch it, and releasing them on the 14th day.
The current suggestions by doctors is to bring in people to the existing facilities from areas where there is not such a high risk. The people that are from high risk areas with evolving strains should be quarantined in proper facilities to make sure that they are not then going to infect other people in quarantine and then spread it through the community.
If you think that vaccination is going to solve the problem, its unlikely on its own and unlikely in the next year or two.
