 The yellow @-@ tailed black cockatoo is found up to 2 @,@ 000 m ( 6 @,@ 600 ft ) AMSL over southeastern Australia including the island of Tasmania and the islands of the Bass Strait ( King , Flinders , Cape Barren islands ) , and also on Kangaroo Island . On Tasmania and the islands of the Bass Strait it is the only native black @-@ coloured cockatoo . On the mainland , it is found from the vicinity of Gin Gin and Gympie in south and central eastern Queensland , south through New South Wales , where it occurs along the Great Dividing Range and to the coast , and into and across most of Victoria bar the northern and northwestern corner , to the Coorong and Mount Lofty Ranges in southeastern South Australia . A tiny population numbering 30 to 40 birds inhabits the Eyre Peninsula . There they are found in sugar gum ( Eucalyptus <unk> ) woodland in the lower peninsula and migrate to the mallee areas in the northern peninsula after breeding . There is evidence that birds on the New South Wales south coast move from elevated areas to lower lying areas towards the coast in winter . They are generally common or locally very common in a wide range of habits , although they tend to be locally rare at the limits of their range . Their breeding range is restricted to areas with large old trees .
