There were diprotodon which was a giant wombat like herbivore that was as big as a rhino, there was procoptus which was a giant kangaroo, there was a giant monitor lizard that grew up to 7m called megalania, there was a giant carnivorous bird called dromornis sirtoni that grew as tall as 10 feet, wanambi which was a giant python that gre 18 feet long and thylacaleo also called the marsupial lion that was a desendant of the wombat and koala that could despite it's size take down a diprotodon. And these are just a few of them.
Australia never occupied Antarctica, nor has any other nation occupied the continent.
Australia is a continent country because the entire continent is occupied by a single country, Australia. No other continent on earth is occupied by a single nation as Australia is.
I don't know about other saber tooth cats, but Smilodon's environment probably because the Earth cooled down getting rid of the megafauna.
The general term for the giant animals that lived in Austalia thousands of years ago is megafauna. Megafauna included animals such as the Diprotodon (rather like a very large wombat), the giant kangaroo and the megalania, which was a gigantic lizard.
