Are there any Australian mammals that are not marsupials?

That's a great question! You might be surprised to learn that there are indeed non-marsupial mammals living in Australia.

Here are a few examples:

* Bats: While bats are mammals, they are not marsupials. Australia is home to a diverse range of bat species, including the spectacled fruit bat, the grey-headed flying fox, and the little bentwing bat.

* Rodents: Australia has several rodent species, like the introduced black rat and house mouse, as well as native species like the bush rat and the hopping mouse.

* Introduced species: While not native to Australia, several non-marsupial mammals have been introduced to the continent by humans, including the red fox, the European rabbit, and the feral cat.

So, while Australia is best known for its marsupials, there are a few other types of mammals that call this landmass home!
