The smooth toadlet (Uperoleia laevigata) is a species of Australian ground-dwelling frog native to the coast and west of the ranges of south-east Queensland, all of eastern New South Wales and north-eastern Victoria. The smooth toadlet reaches 35mm in length. It is grey-brown to olive-brown above often with darker spots and blotches. There is normally a pale triangular patch on the head in front of the eyes and a pale yellow patch in the armpit. It has prominent parotoid glands. Its belly is white and there is a red patch in the thighs.
This frog is associated with dry forest, sclerophyll forest and cleared grassland/farmland along the coast, slopes and ranges. Males make a drawn out "arrrrk" call from around the breeding site, this can be anything from a large permanent dam to a flooded ditch or grassland. Calling males can be right at the waters edge to up to 20 metres away. Calling occurs from spring to autumn. After heavy rain many of these frogs may breed in one or two weeks, when in drier times the breeding site may appear absent of this species.
This species is very similar to two other Uperoleia species, the... Wikipedia →

With luck
About 10% of wildlife watchers report a Smooth Toadlet sighting in Blue Mountains National Park on a given day, based on 8 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 9th most-seen of the 12 amphibians we can rate there. Over three days the chance rises to about 20%, and over a week to about 40%, if each day is a fresh chance.
January, April, July and October–November
In those months about 10% of wildlife watchers report a Smooth Toadlet in Blue Mountains National Park on a given day, against under 5% in February–March, May–June, August–September and December, the lowest months.
Between 8 and 11 pm
Across all the parks we cover, that three-hour window holds the most Smooth Toadlet sightings with a recorded time, and about 6 in 10 of them come between 6 pm and 6 am: it is seen both by day and at night.
Only Blue Mountains National Park, in our data
Blue Mountains National Park is the only park on Wallace's Line with enough records to rate Smooth Toadlet sightings: about 10% of wildlife watchers there report one on a given day.
Same family: Myobatrachidae
The closest relatives of the Smooth Toadlet that you can see in Blue Mountains National Park (family Myobatrachidae, Australian Ground Frogs) are Common Eastern Froglet (about 30%) and Red-crowned Toadlet (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Smooth Toadlet is recorded against all the amphibians logged in Blue Mountains National Park (8 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.
