The platypus inhabits waterways along the eastern and southeastern coast of mainland Australia (to about as far north as Cooktown, Queensland), and on Tasmania and King Island. An introduced population is also found on Kangaroo Island in South Australia, where 19 individuals were released in Flinders Chase National Park in the years be tween 1928 and 1946. The absence of platypus populations in central and western Australia reflects the rarity of permanent lakes or rivers in these areas, while predation by crocodiles may plausibly limit its distribution at the northern end of its range.
