There is no one, specific place where the most marsupials are found in Australia. Marsupials are found in the vast plains of the outback; in the rugged Great Dividing Range in the east and south; in the coastal plains - everywhere.
Marsupials are most common in Australia. They are present in other parts of the world, but all native mammal species in Australia are marsupials (apart from bats).
