The Eastern Regent Parrot Polytelis anthopeplus monarchoides is currently listed as Vulnerable under the Australian Government Environment Protection and Biodiversity Conservation Act 1999 (EPBC Act). It is restricted to a single population occurring in inland south-eastern Australia in the Lower Murray-Darling Basin region of South Australia, New South Wales and Victoria. Riverine and floodplain habitats are known to be critical in supporting the breeding and foraging requirements of regent parrots.
