Australasia has not been joined to the rest of the world by land bridges for tens of millions of years. That's why so much of the fauna is strange and unusual. Humans are one of the few mammalian species that have managed to cross the deep water barriers on our own.

True, you've never been able to just walk it like you could to Tasmania. I mean millions of years ago, Australia was further south -- it's been inching north[1]. Sea levels around the last glacial maximum[2] made the distances much more 'canue-able'. I would consider that at least 'more connected', but you are correct.
