It is endemic to southeastern Australia and is found in eastern Victoria and in southeastern New South Wales.

This is a moderate-sized frog, up to about 60 mm (2.4 in) in length. Its dorsal surface is brown with a few darker flecks. There is a dark stripe that runs from the nostril, above the tympanum, to the groin. There is a lighter golden stripe above and adjacent to the dark stripe.

Possible
About 20% of wildlife watchers report a Blue Mountains Tree Frog sighting in Blue Mountains National Park on a given day, based on 62 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 5th most-seen of the 12 amphibians we can rate there. Over three days the chance rises to about 40%, and over a week to about 70%, if each day is a fresh chance.
October and November
In those months about 30% of wildlife watchers report a Blue Mountains Tree Frog in Blue Mountains National Park on a given day, against under 5% in July to September, the lowest months.
Between 8 and 11 pm
Across all the parks we cover, that three-hour window holds the most Blue Mountains Tree 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.
Yes
Of the 2 parks where we can rate Blue Mountains Tree Frog sightings, Blue Mountains National Park has the highest daily chance: about 20%. Next come Royal National Park (Australia, about 10%).
GBIF citizen-science records
It is estimated from how often the Blue Mountains Tree Frog is recorded against all the amphibians logged in Blue Mountains 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.
