Only in the eastern parts of Australia.
The platypus, specifically the Duck-Billed Platypus, is indigenous to eastern Australia and Tasmania, with the platypus being one of the only mammals that lays eggs (the only other mammal that does lay eggs is the echidna) as mammals generally give birth to live young. The platypus is a semi-aquatic animal and can be found inhabiting streams and rivers in the colder highlands of Australia and Tasmania, as well as tropical rainforests. Platypuses are native to Australia alone. Platypuses live throughout eastern Australia, both in coastal areas and along inland waterways, and its island state of Tasmania, particularly within heavily wooded and protected regions. They are found from the cooler sub-alpine areas in the south, such as Victoria and the Tasmanian highlands, north through New South Wales to tropical far north Queensland. Platypuses live in bushland as well as tropical, sub-tropical and temperate rainforests. Platypuses live in burrows that they dig on the banks of freshwater creeks, rivers, lakes and dams. The female digs a chamber at the end of a long burrow where she shelters her young The platypus is native to the Australian states of Queensland, New South Wales, Victoria and Tasmania. It can also be found in the far east of South Australia. They are found from the cooler sub-alpine areas in the south, such as Victoria and the Tasmanian highlands, north through New South Wales to tropical far north Queensland.

The female digs a chamber at the end of a long burrow where she shelters her young The platypus is one of the most unusual creatures in the animal kingdom. Platypuses (which is the correct plural form, not platypi) have a paddle-shaped tail like a beaver; a sleek, furry body like an otter; and a flat bill and webbed feet like a duck. A strike from a toxic platypus spur can kill a dog. Native to the rivers of eastern Australia, platypus are monotremes—unlike most other mammals, monotremes never evolved live birth, but instead lay eggs like their amniote ancestors. In recent years, there has also been a newly introduced population of platypuses on Kangaroo Island within South Australia. Across the continent of their natural habitat, the platypus mostly lives in freshwater lakes, rivers, lagoons, farm dams, and streams. Most platypuses are found in bodies of water that have earth banks with roots, overhanging vegetation, reeds, and logs to be more suitable for constructing their burrows Platypus live only in the eastern parts of Australia. There are no populations elsewhere in the world. In Australia, the animals are found in Tasmania, Victoria, New South Wales and Queensland to about as far north as Cooktown. Platypus occupy lakes and reservoirs of various sizes, mainly feeding in water that is less than 5 metres deep. They will also sometimes reside in small man-made water bodies, such as park lakes and farm dams-particularly if these are linked directly to streams or rivers for at least part of the year. Endemic to Australia, the platypus can be found in eastern Queensland, New South Wales, throughout Tasmania, and eastern, central, and southwestern Victoria. Across the continent of their natural habitat, the platypus mostly lives in freshwater lakes, rivers, lagoons, farm dams, and streams. The platypus (Ornithorhynchus anatinus) also known as the duck-billed platypus is a semiaquatic egg-laying mammal endemic to eastern Australia, including Tasmania.

Together with the  short-beaked and long-beaked echidna, it is o … ne of the three  species of monotremes, the only mammals that lay eggs instead of  giving birth to live young.
