The Green Tree Frog (Litoria caerulea) is one of Australia's largest and most common frogs, which occurs from South Australia to far north Queensland and the Northern Territory across to the Kimberley in WA.

In the wild Green Tree Frogs occupy a wide range of habitat types, including forests, arid areas and mangrove edges. They adapt well to urban environments and are known to enjoy the damp shelter of pot plants, letterboxes and toilet bowls. They have also become popular pets.

Over the past decades scientists observed a steep decline in frog species, a trend that also affected the Green Tree Frog. The individual frogs can live for over 20 years and adults are still very common. There is however evidence that the number of young Green Tree Frogs is decreasing across the species range.

The Foundation for National Parks & Wildlife funded a survey of the distribution of the Green Tree Frog in coastal NSW. The project aimed to identify any remnant populations within the species range from Eden at the border of NSW and VIC to Grafton in the North. These populations will now be closely monitored.
