At a length of up to 120 mm, this is Australia's largest species of frog. The giant barred frog is night-active and breeds in streams, although the eggs are deposited out of the water under overhanging banks. Clutch sizes are very large, with between 1,343 to 4,184 eggs being counted in the wild. It occurs in both uplands and lowlands in rainforest, as well as farmland, and is found in many protected areas, but is still declining across its range. Threats to this species may include the destruction and degradation of its stream habitat through the impact of invasive species such as weeds and feral animals, timber harvesting and urban development.
