A small species of frog reaching up to nearly 2 cm in body length. It has a reddish-brown or light brown-grey back, with darker patches. The belly is brown, with white mottling and spots. The pupil is nearly round and the iris is gold. The legs have horizontal bars. Fingers and toes are unwebbed, both without discs. The back, arms, and legs are covered with bright white spots.
Eggs are unknown, but are laid in rock pools. Tadpoles can reach a total length of up to 2 cm and are gold in colour, with some dark brown specks. They often remain at the bottom of water bodies, and it is unknown how long they take to develop into frogs. Breeds during spring to summer in the wet season.
Looks similar to Crinia bilingua, Uperoleia borealis, Uperoleia crassa, Uperoleia inundata, Uperoleia micra, and Uperoleia minima in its distribution, but all of these species lack bright white spots on the back and limbs, and all the Uperoleia species, except for Uperoleia micra, have large parotid glands that are not present in Crinia fimbriata.
