Bougainville's skink (Lerista bougainvillii) is a species of skink, a lizard in the family Scincidae. This species is also commonly called the south-eastern slider and Bougainville's lerista. The specific name, bougainvillii, and the common names, Bougainville's skink and Bougainville's lerista, are in honour of French naval officer Hyacinthe de Bougainville.
L. bougainvillii is found in south-eastern Australia, including north-eastern Tasmania and many Bass Strait islands. Bougainville's skink has very reduced limbs and moves in a snake-like manner. The preferred natural habitats of L. bougainvillii are forest and shrubland. However, it is seldom seen, as much of its life is spent beneath leaf-litter, loose sand, and thin stone slabs.
The mode of reproduction of L. bougainvillii varies. Some populations are oviparous, but other populations are viviparous. Cogger HG (2014). Reptiles and Amphibians of Australia, Seventh Edition. Clayton, Victoria, Australia: CSIRO Publishing. xxx + 1,033 pp. ISBN 978-0643100350.

Possible
About 20% of wildlife watchers report a Southeastern Slider sighting in Grampians National Park on a given day, based on 26 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 10th most-seen of the 25 reptiles we can rate there. Over three days the chance rises to about 60%, and over a week to about 80%, if each day is a fresh chance.
August and December
In those months about 40% of wildlife watchers report a Southeastern Slider in Grampians National Park on a given day, against under 5% in April and June, the lowest months.
Between 11 am and 2 pm
Across all the parks we cover, that three-hour window holds the most Southeastern Slider sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Only Grampians National Park, in our data
Grampians National Park is the only park on Wallace's Line with enough records to rate Southeastern Slider sightings: about 20% of wildlife watchers there report one on a given day.
Same family: Scincidae
The closest relatives of the Southeastern Slider that you can see in Grampians National Park (family Scincidae, Skinks) are Shingleback Lizard (about 70%), Cool-temperate Water Skink (about 70%) and Black Crevice-skink (about 60%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Southeastern Slider is recorded against all the reptiles logged in Grampians National Park (26 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.
