Problem is the vast, vast majority of Australia is unlivable or nearly, unless you have a well planned homestead (i.e. your own property) where you can have water security and livestock.
Even the greener areas are absolutely desolate and rugged, and even the most established rivers and creeks away from civilization are prone to dry up for months at a time. Food supplies are going to be very difficult as well, kangaroos are numerous but not in areas that a human would want to live and be able to hideout, very few large mammals to eat and bushland has very little in the way of edible fruits and vegetables. Surviving on bushrats and roots without effective water management is an eventual death sentence.
I recently camped out a few days in Yengo National Park which is fairly green and lush, and so gigantic that you could disappear deep into the canyons and never see another human being again for perhaps decades. I was really shocked at how impossible the terrain is. Bush too thick to walk through and you won't make it more than an hour before you need legit climbing gear. It's like Bryce canyon but the size of 4 Rhode Islands and covered with horribly impassible bush, waste deep grass and vines full of snakes and spiders. You'll go days without food and you still wouldn't have found a safe place to setup your camp, and probably just a few trickles of dirty water between the canyons. And god save you when a bushfire starts.
