The leaf green tree frog (Dryopsophus phyllochrous) is a species of stream-dwelling frog, native to eastern Australia from the Queensland/New South Wales border south to Sydney. This is a fairly small species of tree frog, up to about 40 mm (1.6 inches) in length. It can be light green to dark olive green to light brown to dark brown on the dorsal surface. A pale golden stripe runs from the nostril, across the eye, over the typanum, and down the side, underlined by a dark brown stripe, which also goes over the typanum, not across it. The forelimbs, groin, and thighs are dark red. The toes are three-quarters webbed and toe discs are large. The belly is white.
This species inhabits flowing streams in rainforest, woodland, and wet or dry sclerophyll forest along the coast and ranges of New South Wales. Males make an "Erk..Ek..Ek..Derk" call from stream-side vegetation during spring, summer and autumn, especially on warm nights; they are often seen in suburban creeks around Sydney and near the sea.

Possible
About 30% of wildlife watchers report a Leaf Green Treefrog sighting in Royal National Park on a given day, based on 62 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 3rd most-seen of the 9 amphibians we can rate there. Over three days the chance rises to about 60%, and over a week to about 90%, if each day is a fresh chance.
September and December–January
In those months about 40% of wildlife watchers report a Leaf Green Treefrog in Royal National Park on a given day, against under 5% in July, the lowest month.
Between 8 and 11 pm
Across all the parks we cover, that three-hour window holds the most Leaf Green Treefrog sightings with a recorded time, and about 7 in 10 of them come between 6 pm and 6 am: it is mostly seen at night.
Yes
Of the 2 parks where we can rate Leaf Green Treefrog sightings, Royal National Park has the highest daily chance: about 30%. Next come Blue Mountains National Park (Australia, about 20%).
GBIF citizen-science records
It is estimated from how often the Leaf Green Treefrog is recorded against all the amphibians logged in Royal National Park (62 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.
