With luck
About 10% of wildlife watchers report a Pobblebonk sighting in Blue Mountains National Park on a given day, based on 24 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 7th most-seen of the 12 amphibians we can rate there. Over three days the chance rises to about 30%, and over a week to about 60%, if each day is a fresh chance.
January and March
In those months about 20% of wildlife watchers report a Pobblebonk in Blue Mountains National Park on a given day, against under 5% in May, July–August and October, the lowest months. Those are among Blue Mountains National Park's wettest months, with about 140 mm of rain a month against 40 mm in May.
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.
6th of 6
Of the 6 parks where we can rate Pobblebonk sightings, Blue Mountains National Park ranks 6th at about 10%. The best odds are in Hattah-Kulkyne National Park (Australia, about 30%), Grampians National Park (Australia, about 30%) and Kosciuszko National Park (Australia, about 20%).
GBIF citizen-science records
It is estimated from how often the Pobblebonk is recorded against all the amphibians logged in Blue Mountains National Park (24 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.
