The skink is either Pseudemoia entrecasteauxii or Lampropholis guichenoti. Given the subalpine elevation of the site it could well be the former but L. guichenoti can also occur (far less commonly) up to about 1600 m in the ACT. The photograph I am seeing on CNM is blurry. Is the original also out of focus? If it is good and sharp you could resubmit the photo.
Hi Will! Sorry about the photo quality - I haven't quite figured out how to get the best out of that camera yet and especially not with wildlife... the photo is indeed blurry I am afraid.
