The white-lipped treefrog is Australia's largest native frog growing up to 14 cm. Ranging in colour from pure green to greenish-brown or pale brown, it has a brilliant white stripe that runs along its lower jaw and the side of its head. During the breeding season some have a salmon-pink coloration on their arms and legs. The tadpoles are dark brown with a single cream stripe on each side of the head, body and tail.
