Pseudemoia entrecasteauxii, also known commonly as Entrecasteaux's skink, the southern grass skink, the tussock cool-skink, and the tussock skink, is a species of lizard in the family Scincidae. The species is endemic to Australia.

The southern grass skink has a lifespan of about 5 or 6 years. P. entrecasteauxii grows up to 7.5 cm (3.0 in) in length (not including the tail). Male skinks change colouration during the breeding season. The specific name, entrecasteauxii, is in honor of French naval officer and explorer Antoine Bruni d'Entrecasteaux.
The southern grass skink has become a model species for reproductive biology in reptiles because it gives birth to live young and exhibits non-invasive epitheliochorial placentation. Unlike the majority of live bearing reptiles, Pseudemoia develop complex placentae, which provide a substantial... Wikipedia →

With luck
About 10% of wildlife watchers report an Entrecasteaux's Skink sighting in Grampians National Park on a given day, based on 8 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 22nd most-seen of the 25 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.
January
In that month about 30% of wildlife watchers report an Entrecasteaux's Skink in Grampians National Park on a given day, against under 5% in April to November, the lowest months.
Between 1 and 4 pm
Across all the parks we cover, that three-hour window holds the most Entrecasteaux's Skink sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
2nd of 3
Of the 3 parks where we can rate Entrecasteaux's Skink sightings, Grampians National Park ranks 2nd at about 10%. The best odds are in Kosciuszko National Park (Australia, about 40%).
GBIF citizen-science records
It is estimated from how often the Entrecasteaux's Skink is recorded against all the reptiles logged in Grampians National Park (8 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.
