How to identify it

Green or brown with irregularly spaced, rounded dark spots on the back and a few on the sides. [1]

A continuous, usually yellowish ridge runs along each side of the back. [1]

Head is pointed; usually a light spot in the centre of the eardrum. [1]

Hind toes are extensively webbed; adults reach about 13 cm snout-vent length. [1]

Breeding call is a short chuckling or ratchet-like trill; breeding males have spherical vocal sacs at the angles of the jaw. [1]

Field knowledge

Where it lives

Occurs near virtually any freshwater habitat and in some places slightly brackish marshes. [1]

Breeds in still, shallow, permanent or temporary water. [1]

Field knowledge

How it behaves

Males call from shallow or deep water, floating or submerged, sometimes from crayfish burrows. [1]

Breeds usually March-June in the north of the range and in any month in the far south. [1]

In summer may disperse from water into moist upland vegetation; migrates between breeding pools and adjacent terrestrial habitat; inactive in cold winter weather in the north. [1]

Adults eat small terrestrial invertebrates; egg masses are baseball-sized and hold roughly 1,000-1,500 eggs. [1]

Where legal take is listed

Being listed is not an open season. Seasons, zones, licences, methods and limits decide whether this animal may be taken on a given day and place — check Hunt or the authority before you go. Listings read 2026-09-30.
