Five years imprisonment and/or a $66,600 fine for refusing coronavirus vaccination?

From Australia, I’m watching the fast-tracked development of coronavirus vaccines with mounting concern.

Under the Australian Biosecurity Act 2015, refusers of coronavirus vaccination[1] in Australia could be at risk of five years imprisonment and/or a $66,600 fine.[2] [3]

This emergency power has been active since March 2020, and has been extended to December 2020 [4], with the potential for unlimited extensions.[5] 

It’s possible this emergency power could be extended until a coronavirus vaccine is available, and that people in Australia could be under duress to have coronavirus vaccination, i.e. at risk of imprisonment and/or a huge fine, for a virus which is not a threat to most people under 70.[6]
