The wallum froglet (Crinia tinnula) is a species of ground-dwelling frog native to the east coast of Australia, from southeast Queensland to Kurnell, NSW.

It is very similar to the common eastern froglet, and can only readily be distinguished by call and a white stripe on the throat that reaches all the way to the tip on the snout.

Its dorsal surface is variable, it can range from grey to brown and is normally smooth in texture.

Males make a high pitched squeaking noise and call at any time of the year, when water is available.

Tadpole development takes nearly 6 months, with metamorph frogs ranging from 6–11 mm.
