Endemic Range Context

This species is endemic to Southwest Australia, and is one of only four members of its diverse genus that occurs in the region.

Habitat Preference

It is found in southern coastal areas, where it favors permanent water and granite outcrops. At its northernmost range extent, it can also be found in agricultural dams.

Recorded Sightings

Confirmed sightings have also been recorded at Middle Island in the Archipelago of the Recherche, and at Coragina Rock.

Natural Habitats

Its natural habitats include rivers, swamps, freshwater lakes, and freshwater marshes.

Conservation Status

While habitat loss poses a threat to this species, it is currently classified as least concern for extinction.

Non-Native Establishment

There are documented concerns that this species, the spotted-thighed tree frog, has recently become established on the Eyre Peninsula of South Australia.

Potential Invasive Impacts

It may spread further east into the Murray-Darling Basin, where it could interbreed with or displace local threatened species.
