The ID is correct. Can you tell us the approximate date (month will do) you actually saw this Guthega Skink Liopholis guthega (and the other one). I expect that now (June) they would be in brumation at that site.
Yep, these were back from 10 February 2013 - I too would not expect them to be out at this time of year! (I've been looking back through some of my old photos, to see if any are worth posting on CNM)
Thanks for letting me know. We dont have many records for the Guthega Skink in any records (NSW Wildlife Atlas etc) so all good records like this are really helpful. Cheers, Will Osborne
