If they (whoever they are) wanted everyone to get vaccinated all they would have to do is get insurance companies to announce they will be no longer paying any of the hospital bills. If this was to happen and the hospitals were to say no insurance no care, then what would people do? Of course, this is against the reason there are hospitals.
Conservatives do not want insurance companies to tell them what to do . They do not want to pay for other people's insurance, they have no idea how insurance works, let the conservatives live by their own rules for a while.

I suppose that if you were in a crashing plane and the captain ordered everyone to put on a parachute, there would be plenty of arse holes who would refuse because no one tells them what to do, and parachutes cause cancer or impotence and the whole plane crash story is a hoax anyway.
Well fine, let them sit in their seats as the plane plunges to a firey death.
Though some people might break a leg or wrist because they haven't bee trained in parachuting, chances are they won't die from doing the sensible thing and getting of the damned plane.
To be honest I thought Australians had a bit more sense than this, but stupidity does not recognize borders.

After all the crap with Novak Djokovic, then they switch to this the next day?

If it gets rid of the nazi-like wackos, yes.

Happened 15th of December.
Vaccinate all who want then let is rip, I totally agree. Plus there is a time restriction ie before vax's are useless ie within 4 months (booster recommended). Australia is around 90% vaxxed (so they say)
If you don't open up and everyone has been coerced into getting vaccinated, then what is the fucking point of everyone getting vaccinated?
It's almost as though authorities don't trust the vax will work like a vax should, work the way it was sold to everyone, you know "highly efficient and perfectly safe".
