The green tree frog is native to northern and eastern parts of Australia. They are also native to southern New Guinea. In New Guinea, the green tree frog lives in the drier area of the country. The frog can be found from Irian Jaya to Port Moresby. It also can be found on Daru Island. There has been records of the frog found in northern New Guinea. However, it is thought that they were introduced there by humans. The International Conservation Union (IUCN) believes the frog is in "scattered locations" in both New Guinea and Indonesia.
