The Green and Golden Bell Frog (Litoria aurea) is a ground-dwelling tree frog native to eastern Australia. It is also known as the Green Bell Frog, Green and Golden Swamp Frog and Green Frog. Measuring 11 centimetres (4.3 in) in length, the Green and Golden Bell Frog is one of the largest Australian frogs. Many populations, particularly in the Sydney region, are in areas of frequent disturbance, including golf courses, disused industrial land, brick pits and landfill areas. Once one of the most common frogs in south-east Australia, the Green and Golden Bell Frog has undergone major population declines, leading to its current classification as globally vulnerable. Population numbers have continued to decline and major threats include habitat loss and degradation, pollution, introduced species, parasites and pathogens, such as the amphibian chytrid fungus.
