After reading all the Sturm und Drang of Australia's response to the Covid virus, I decided to take a closer look.
I stumbled across the video (linked above) showing part of their response; that is, very large concentration camps.
Australia decided that packing huge numbers of people who MIGHT have been exposed to Covid into close proximity is a good idea. That is the biological equivalent of packing all of your U-235 into one, big pile.
Yes, yes, yes...I know it is very convenient for the bureaucrats who want to track and control potential carriers as well as creating a bunch of jobs for minions. But it completely misses the point of fire-walling potential contagion.
Covid (in all of its mutations) is in every large country already, including Australia. Mandatory in-house quarantines are a splendid idea. Fine people if their cell-phone GPS leaves the home but don't incarcerate them behind razor-wire in close association with other travelers.
If you want to employ your mouth-breathers, then hire them to deliver food to the quarantined traveler's doorstep.
