This endemic of northern Australia is known from the eastern Kimberley’s of Western Australia and into the western escarpment of Arnhem Land in the Northern Territory. The estimated altitudinal range of the species is from 150-600m asl.
Habitat and Ecology
The species is associated with rocky habitats-sandstone hills and gorges, rocky screen and ledges, boulder fields, caves and open escarpments, usually near perennial and non-perennial streams. It shelters deep in caves. It breeds in spring and summer. Males call from beneath boulders in or near the streambed. About 350-400 eggs are laid in a foam nest in rock pools or beneath rocks at the edge of water-draining scree slopes. Tadpoles develop in ponds in about 9 weeks.
It is estimated to have a population size less than 50,000, but greater than 10,000. The low estimate is based on the small known range of the species.
There are no known threats to the species.
Its range includes multiple protected areas in Western Australia and the Northern Territory.
Red List Status
Least Concern (LC)
Listed as Least Concern in view of its wide distribution, presumed large population, and because its population is not believed to be in decline at present.
