Endemic of Australia, where there are four populations, one of which is isolated in the southeast of Western Australia, from the West of the Nullarbor plain up close Kalgoorlie.

Birds belonging to this Western race is also in the West of Southern Australia, about Ooldea and Colona, but they are probably from exhaust. Further East, the species range in the East of Southern Australia, from the West of Bordertown through Salt Creek, Adelaide, the northern parts of the Cape York Peninsula and Eyre, to the North across the basin of the Lake Eyre to the Simpson Desert, about Commonwealth Hill station (but largely absent from the Montes Flinders).
