The southwestern cool-skink (Acritoscincus trilineatus) is a species of skink. The species was described in 1838 by John Edward Gray, based on a specimen held at the British Museum of Natural History, the author assigning it to the genus Tiliqua.
Common names for the species include western three-lined skink, New Holland skink and southwestern cool-skink, a name that refers to the cooler climates of its southern distribution range. A species of Acritoscincus found in the Southwest Australia region and an isolated population in South Australia. Their body is moderately stocky in form, with smooth scales, functional and strong limbs that each have five digits. Their total length, from head to tail, is around 190 millimetres, the snout to vent length is 70 mm.
Both the sexes have a red patch at their throat which varies in its intensity of colour, becoming more noticeable during the breeding season. The coloration of A. trilineatus resembles the species Pseudemoia entrecasteauxii, the southern grass-skink, which occurs in a similar distribution range.
It is found in damp and cool habitat, such as wetlands, and often basking... Wikipedia →

With luck
About 10% of wildlife watchers report a Western Three-lined Skink sighting in Perth on a given day, based on 15 verified sightings from GBIF citizen-science data. It is the 17th most-seen of the 23 reptiles we can rate there. Over three days the chance rises to about 20%, and over a week to about 40%, if each day is a fresh chance.
January–May, August and October–November
In those months about 10% of wildlife watchers report a Western Three-lined Skink in Perth on a given day, against under 5% in June–July, September and December, the lowest months.
Between 10 am and 1 pm
Across all the parks we cover, that three-hour window holds the most Western Three-lined 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.
Only Perth, in our data
Perth is the only city on Wallace's Line with enough records to rate Western Three-lined Skink sightings: about 10% of wildlife watchers there report one on a given day.

GBIF citizen-science records
It is estimated from how often the Western Three-lined Skink is recorded against all the reptiles logged in Perth (15 verified sightings), 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.
