Peron's Tree Frog
Litoria peronii

Peron's Tree Frog is a common species in the south-east of Australia and can be found around human habitation. They are easily recognised for the bright green spots on the back of the light grey-brown body and for the black and yellow barring on parts of the legs, feet and areas of the underparts. They are particularly good at climbing and can also change colour quickly - in the two photos below, the colour matches the backdrop. Unlike most other related frogs, it's pupils are cross-shaped, whereas the others are slits. They are medium-sized at 4.4 - 6.5 cm, with the females being the larger. Their call is often likened to a manic cackle.
