Spotted Grass Frog
Limnodynastes tasmaniensis

Spotted Grass Frogs are a relation of the Eastern Banjo Frog and are found over a more extensive range, from central Queensland round to the central coast of SA and much further inland to the corner of Qld, NSW and NT. They are also smaller at 3.1-4.7 cm. They breed all year round, depending on climate conditions and are found near still water, rather than running.
