This is a fairly small species of tree frog, up to about 40 mm (1.6 inches) in length.

This species inhabits flowing streams in rainforest, woodland, and wet or dry sclerophyll forest along the coast and ranges of New South Wales.

Males make an "Erk..Ek..Ek..Derk" call from stream-side vegetation during spring, summer and autumn, especially on warm nights; they are often seen in suburban creeks around Sydney and near the sea.
