Firstly your "quarantine camp" is actually a quarantine facility. These were setup because people wanted an alternative to hotel quarantine (because these were ineffective). This facility was for travelers not for random Australians.
We didn't have this facility in Victoria, it was only for NT. We had to quarantine at home. A lot of Victorians weren't happy about not having a similar facility because the hotel quarantine that Victoria had in place wasn't as effective. We would go to zero cases and then a some staff would get covid from the hotel and spread it.
We quarantined at home. My family got sick and guess what, they weren't "dragged off" by the Gestapo, they just stayed at home for 7 days.
Fox News isn't the best source of information fyi.
Regardless, Australia is a democracy (I am not sure if you knew this), if these were unpopular, the parties involved will be voted out. Australia has preferential voting so there is no reason why an anti lockdown party couldn't win.
