The red-crowned toadlet (Pseudophryne australis) is a species of Australian ground frog, restricted to the Sydney Basin, New South Wales. It is only found around sandstone escarpment areas around Sydney, from Ourimbah in the north, Nowra to the south and the Blue Mountains areas to the west.
This is a small species of frog, reaching 30 mm in length. It is characterised by the red T-shaped mark on its head. It is dark brown or black above with a red wash or spots over its back, and a red mark near the vent. The sides are a blue-grey and there is a white mark in the armpits and thighs. The ventral surface is very strongly marbled black and white, with a bluish colour in some areas between the black and white.
This species is only found around temporary creeks and soaks in sandstone habitats in woodland, heathland and dry sclerophyll forest around the Sydney basin. Males make an ark call from nest sites under leaf litter and rocks, in areas likely to be inundated, generally only after heavy rain. Eggs are laid under leaf litter and tadpoles begin developing inside the egg, the males stays with the eggs in the nest. Once heavy rain floods the... Wikipedia →

Possible
About 20% of wildlife watchers report a Red-crowned Toadlet sighting in Royal National Park on a given day, based on 25 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 6th most-seen of the 9 amphibians we can rate there. Over three days the chance rises to about 40%, and over a week to about 80%, if each day is a fresh chance.
June
In that month about 40% of wildlife watchers report a Red-crowned Toadlet in Royal National Park on a given day, against under 5% in January, March, July and October, the lowest months.
Between 8 and 11 pm
Across all the parks we cover, that three-hour window holds the most Red-crowned Toadlet sightings with a recorded time, and about half of them come between 6 am and 6 pm: it is seen both by day and at night.
Yes
Of the 2 parks where we can rate Red-crowned Toadlet sightings, Royal National Park has the highest daily chance: about 20%. Next come Blue Mountains National Park (Australia, about 10%).
GBIF citizen-science records
It is estimated from how often the Red-crowned Toadlet is recorded against all the amphibians logged in Royal National Park (25 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.
