A small species of frog reaching up to 2.5 cm in body length. It has a dark brown, grey or nearly black back, with or without darker patches, and lighter longitudinal stripes along the sides. There is sometimes a longitudinal stripe along the middle of the back. The belly is usually white with black patches, but becomes black or grey in breeding males, with a white stripe or cross shape. The pupil is nearly round and the iris is gold. The legs have horizontal bars. Fingers and toes are unwebbed, both without discs.
Eggs are laid singly and attached to vegetation under the water in swamps, creeks, or pools. Tadpoles can reach a total length of up to 3.5 cm, and are dark brown, gold, or sandy brown in colour. They often remain on the bottom of water bodies, and take around four months to develop into frogs. Breeds during late winter to early summer.
Looks most similar to Crinia georgiana, Crinia insignifera, Crinia pseudinsignifera, and Crinia subinsignifera in its distribution, but has a different call, and lacks the bright red patches in the armpits, groin, and thighs present in Crinia georgiana.
