This is the list of rodents of Australia. Australia has a large number of indigenous rodents, all from the family Muridae. These are presumed to have arrived within the last 4 million years from Asia. The black rat, brown rat, Pacific rat and house mouse were accidentally introduced to Australia with European settlement, as was a small population of the five-lined palm squirrel near Perth.
