The Tasmanian she-oak skink, also known simply as the she-oak skink (Cyclodomorphus casuarinae) is a large (up to about 30 cm total length), long-tailed (over 60% of body length), snake-like skink endemic to Tasmania, Australia. It is viviparous; mating in spring, and giving birth in late summer. It is related to the more robust blue-tongued skink, of the genus Tiliqua, and was previously known as Tiliqua casuarinae.

Possible
About 20% of wildlife watchers report a She-oak Slender Bluetongue sighting in Freycinet National Park on a given day, based on 12 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 7th most-seen of the 9 reptiles we can rate there. Over three days the chance rises to about 60%, and over a week to about 90%, if each day is a fresh chance.
February
In that month about 40% of wildlife watchers report a She-oak Slender Bluetongue in Freycinet National Park on a given day, against under 5% in April to September, the lowest months.
Between 1 and 4 am
Across all the parks we cover, that three-hour window holds the most She-oak Slender Bluetongue sightings with a recorded time, and about 7 in 10 of them come between 6 pm and 6 am: it is mostly seen at night.
Only Freycinet National Park, in our data
Freycinet National Park is the only park on Wallace's Line with enough records to rate She-oak Slender Bluetongue sightings: about 20% of wildlife watchers there report one on a given day.
Same family: Scincidae

GBIF citizen-science records
It is estimated from how often the She-oak Slender Bluetongue is recorded against all the reptiles logged in Freycinet National Park (12 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.
