New South Wales, Australia.
Sometimes placed in genus Lophochroa; recent molecular study indicates that present species is sister to the other members of Cacatua and may, therefore, merit generic separation#R. Has hybridized in the wild with Eolophus roseicapilla#R. Formerly subdivided into three subspecies on basis of size and of the quantity and colouring of crest feathers, but study of 22 wild-caught pairs and examination of museum skins showed that criteria for subspeciation could hardly be upheld; form mollis (C Western Australia to Northern Territory and W South Australia), with little or no yellow in crest, is sometimes retained, but very poorly differentiated and not recognized here. Treated as monotypic.
Throughout much of inland Australia, from S Kimberley region (Western Australia) and EC Northern Territory S to CW coast near Geraldton and S coast at Eyre, then through inland South Australia (mainly in SC areas), NW Victoria and New South Wales to S Queensland.
Introduced around Sydney and, unsuccessfully, in Fiji.
