The Australian green tree frog (Pelodryas caerulea), also known as simply green tree frog in Australia, White's tree frog, or dumpy tree frog, is a species of tree frog native to Australia and New Guinea, with introduced populations in the United States and New Zealand, though the latter is believed to have died out. It is morphologically similar to some other members of its family, particularly the magnificent tree frog (P. splendida) and the white-lipped tree frog (Sandyrana infrafrenata).
Larger than most Australian frogs, the Australian green tree frog reaches 10 cm (4 in) or more in length. Its average lifespan in captivity, about 16 years, is long compared with most frogs. Docile and well suited to living near human dwellings, Australian green tree frogs are often found on window sills or inside houses, eating insects drawn by the light. The green tree frog screams when it is in danger to scare off its foe, and squeaks when it is touched.
Due to its appearance and behavioural traits, the green tree frog is a popular exotic pet throughout the world. The skin secretions of the frog have antibacterial and antiviral properties that may prove useful in pharmaceutical preparations and which have rendered it relatively immune to the population declines being experienced by many species of amphibian. It is a common species and the International Union for Conservation of Nature has assessed its conservation status as being "least concern".

Possible
About 30% of wildlife watchers report a Blue Frog sighting in Kakadu National Park on a given day, based on 32 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 3rd most-seen of the 13 amphibians we can rate there. Over three days the chance rises to about 70%, and over a week to about 90%, if each day is a fresh chance.
December to February
In those months about 60% of wildlife watchers report a Blue Frog in Kakadu National Park on a given day, against under 5% in March and August, the lowest months. Those are among Kakadu National Park's wettest months, with about 300 mm of rain a month against almost none in August.
Between 7 and 10 pm
Across all the parks we cover, that three-hour window holds the most Blue Frog sightings with a recorded time, and about 8 in 10 of them come between 6 pm and 6 am: it is mostly seen at night.
2nd of 5
Of the 5 parks where we can rate Blue Frog sightings, Kakadu National Park ranks 2nd at about 30%. The best odds are in Pilliga National Park (Australia, about 60%). All parks ranked.
GBIF citizen-science records
It is estimated from how often the Blue Frog is recorded against all the amphibians logged in Kakadu National Park (32 verified sightings from 2019 to 2026), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
