The frog is also called the pobblebonk after its distinctive "bonk" call, which is likened to a banjo string being plucked. There are five subspecies of L. dumerilii, each with different skin coloration. The species is native to eastern Australia. There has been one occurrence in New Zealand, when tadpoles of the species were found in 1999 and destroyed.
Adults are roughly seven to eight centimetres (2.8 to 3.1 in) long with dark warty backs, a prominent tibial gland, fleshy metatarsal tubercules and a smooth white or mottled belly. The tadpole stage is relatively long, lasting up to fifteen months. The species is common.

Possible
About 20% of wildlife watchers report a Pobblebonk sighting in Kosciuszko National Park on a given day, based on 17 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 3rd most-seen of the 5 amphibians we can rate there. Over three days the chance rises to about 50%, and over a week to about 80%, if each day is a fresh chance.
November
In that month about 40% of wildlife watchers report a Pobblebonk in Kosciuszko National Park on a given day, against under 5% in February, May–July and September, the lowest months.
Between 6 and 9 pm
Across all the parks we cover, that three-hour window holds the most Pobblebonk sightings with a recorded time, and about 6 in 10 of them come between 6 pm and 6 am: it is most active around dawn and dusk.
3rd of 6
Of the 6 parks where we can rate Pobblebonk sightings, Kosciuszko National Park ranks 3rd at about 20%. The best odds are in Hattah-Kulkyne National Park (Australia, about 30%) and Grampians National Park (Australia, about 30%).
GBIF citizen-science records
It is estimated from how often the Pobblebonk is recorded against all the amphibians logged in Kosciuszko National Park (17 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.
