In Australia the Cotton Pygmy-Goose ranges along the East coast from NSW to QLD but is now only a rare visitor and listed as Endangered in NSW.
Cotton Pygmy-Geese may be found in freshwater lakes, lagoons, swamps and dams containing water lilies and other aquatic vegetation.
They require dead trees with hollows located close to water for roosting and breeding.
Clearing, draining, use of chemicals and heavy grazing of and around lakes and wetlands as well as introduced weeds and feral cats and foxes, are the main threats’ and reasons for their decline.
Cotton pygmy geese are considered a key wetland indicator in Queensland, especially in regards to the aquatic vegetation condition.
