Lake Woongeel on Fraser Island, south-east coastal Queensland to Kurnell mid-eastern New South Wales. The extent of occurrence of the species is approximately 30300 km2. There is no information on population size, structure, dynamics, genetics, non-breeding habitat requirements or factors limiting distribution.

Life History, Abundance, Activity, and Special Behaviors
In acid Melaleuca swamps, and wallum areas with poor drainage. Breeding occurs in July and August. Eggs are deposited in water with pH 4.3 – 5.2. More information in Straughan & Main (1966), Ingram & Corben (1975) and Ehmann (1977).

Trends and Threats
Continuing decline in area of occupancy, number of locations, number of mature individuals. Severely fragmented habitat – it was assumed that the population is naturally fragmented, but increasing fragmentation through habitat destruction and degradation, particularly mainland populations.

Threats
Localised extermination of populations due to loss or fragmentation of habitat.

Conservation Measures
Listed as vulnerable and protected in some National Parks in both Queensland and New South Wales (including Fraser Island).
