From the IUCN Red List Species Account:

 

Range Description

This species is widespread in Australia, from the Kimberley zone of Western Australia through northern part of the Northern Territory and into northern Queensland and down the coast to Bowen in coastal Queensland. In the New Guinea region, it is known only from the Aru Islands including Naiguli and Terangan. There is some doubt regarding whether or not the specimens assigned to this species in the Aru Islands is actually another species.

Habitat and Ecology

This species is most abundant in grassland or marshy areas, often forming vast populations. It is found around permanent or semi-permanent streams, billabongs, and floodplains. Breeding begins with the summer rain. Males call from grass stems, bushes and small trees inundated by or surrounding water. About 10-20 eggs are laid in temporary pools in small clumps attached to submerged vegetation. Tadpoles metamorphose in 70-80 days.
Its habitat preferences on the Aru Islands are not known. If it presumed that, the habitat preferences are similar to that of the Australian populations and to other members of this species complex.

Population

The population status of the species in the Aru Islands is unknown.

Population Trend

Stable

Major Threats

Agriculture might pose a threat in Queensland. Sometimes individuals are relocated through transportation of fresh produce. There are no threats specifically known for this species on the Aru Islands, however the Aru Islands are being logged and cleared for agricultural land, which is most likely affecting the species' habitat.

Conservation Actions

The range of the species includes several protected areas in Australia. The taxonomic status and Extent of Occurrence of the southern New Guinea populations need to be determined.

Taxonomic Notes

The taxonomic status of the New Guinea populations referred to Litoria bicolor requires confirmation based on call structure or genetics (S. Richards pers. comm.).
