I want the choice on how I live I can keep myself and my family safe.
You are in the wrong country if you think you have much say in that. Australia is a Democratic Socialist country, that means the community elects leaders to decide what is best for the community, not for the individual. The only country remotely closer to the Libertarian society you are thinking of is the USA, even that is far from being able to "do what you want" free of the state. And to be honest, you don't want to be a true Libertarian, providing your own medical care and general infrastructure might be harder than you think.
What you are really saying is "I want the ability to do what I did before Covid", which is an ever changing thing, you just notice the big changes like Covid settings.
You get to choose how you live your life within the boundaries of Australian rules and society. Right now the rules are adjusted for pandemic settings, just like they are for wartime or terrorism etc.
