Distribution and habitat preferences

It is an Australian endemic, usually confined to the arid inland.

They have been sighted over most of mainland Australia except for Cape York. Very few have been seen on the Nullarbor Plain and in the Great Victoria, Gibson and Great Sandy Deserts. Most sightings have been within the arid zones, with rainfall less than 500mm. When they have been occasionally seen outside of these areas, they have been found in similar dry, low altitude, open woodland or grassland. (Wikipedia)
