Isn't that exactly what a slippery slope is? Why should it matter if it is only for a small group of people and not all citizens? It's the most insane measure I've seen regarding the pandemics that isn't in China. Even if you would do this for only 1 person, why should that be accepted? Other countries are dealing well with the pandemics without that kind of Orwellian process. At this point I cannot imagine what can make Australians realize that you cannot isolate from a global pandemics in a hyper-connected world, and the only thing you get from a zero covid approach are the first stones for a surveillance state.
