Giant Burrowing Frog
The threatened Giant Burrowing Frog Heleioporus australiacus is a large, cryptic amphibian from south-eastern Australia. Its known range extends from east of Walhalla in Victoria along the Great Dividing Range to Newcastle in NSW, where it has been recorded from various forested habitat types. Despite this wide distribution, limited records exist towards the southern extent of its range in Victoria where it is now considered Critically Endangered compared to a national listing of Vulnerable. It is so rarely encountered that until recently information on the species’ ecology barely extended beyond a limited number of incidental observations.
