The genus Eolophus contains a single Australian species; the Galah - Eolophus roseicapilla (Vieillot, 1817).
The Galah is one of the most common and widespread cockatoos in Australia; it can be found in open country in most parts of the mainland.
The Galah is endemic to Australia but the sub specie E.r. albiceps has been introduced on Tasmania.
Originally the Galah was classified as Cacatua roseicapilla but recent studies have moved it to the monotypic Eolophus genus; the Cacatua genus now only contains the white cockatoos.
