Saproscincus challengeri, also known commonly as the Border Ranges shadeskink, Challenger's skink, the challenging shade skink, and the orange-tailed shadeskink, is a species of lizard in the family Scincidae. The species is native to New South Wales and Queensland in Australia.
George Albert Boulenger, herpetologist at the British Museum (Natural History) named S. challengeri after the Challenger expedition in 1887. The preferred natural habitat of S. challengeri is forest, at altitudes from sea level to 500 m (1,600 ft).

With luck
About 10% of wildlife watchers report a Border Ranges Shadeskink sighting in Lamington National Park on a given day, based on 11 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 25th most-seen of the 38 reptiles 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.
March
In that month about 30% of wildlife watchers report a Border Ranges Shadeskink in Lamington National Park on a given day, against under 5% in January and June–September, the lowest months. That is one of Lamington National Park's wettest months, with about 150 mm of rain against 40 mm in August.
Between noon and 3 pm
Across all the parks we cover, that three-hour window holds the most Border Ranges Shadeskink sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Only Lamington National Park, in our data
Lamington National Park is the only park on Wallace's Line with enough records to rate Border Ranges Shadeskink sightings: about 10% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Border Ranges Shadeskink is recorded against all the reptiles logged in Lamington National Park (11 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.
