Australia's population is 10 million less than California's, and its landmass is almost the size of the US. There are more remote than populated areas, but the terrain is tricky.
Tasmania's fresh, pristine water supply and other natural resources are ideal, but the Antarctic breeze in the winter is brutal.
Queensland often receives too much water and unbearably hot, humid summers, but the rainforest is lush.
Victoria, where I live, has areas within a few hours' drive that are liveable and somewhat remote, but I'm in a city of 5 million, considered population-dense by Australian standards.
The most remote place on Earth (maybe) is Darwin, in the far northwest. There is no light pollution for hundreds of miles, and the Milky Way streaks across the night sky, but crocodiles dominate the saltwater regions.
Fortunately, Australians are less shit than Americans but equally as racist. They scrutinize and have a healthy distrust of the government because it will do whatever the UK and the US say. No one would notice if Australia fell off the face of the world until the Western empires wanted something. It's easier than living in the empire, but Australia is far from perfect.
