The tiny Wallum Froglet (Crinia tinnula) lives in the coastal heaths and wetlands from Sydney to south-eastern Queensland. Its appearance varies - its skin can be smooth, warty or ridged and range in colour from brown to grey, usually with a white stripe from its chin to its belly.
Along with the Cooloolah Tree frog, the Olongburra Frog and the Freycinet’s Frog, the Wallum Froglet forms the group of native acid frogs which only breed in areas of low pH.
The Wallum Froglet inhabits acid paperbark swamps and Wallum country, ranging from heath plains to rainforests.
The Foundation for National Parks & Wildlife funded research into the ecology and physiology of the Wallum Froglet, which is easily confused with two other similar species, to enable targeted conservation actions.
