Speckled Wall Skink or Ragged snake-eyed skink
Identified as Cryptoblepharus pannosus on Bowerbird by Matt Campbell: "Pretty sure I have this one right. It immediately cried C. australis to me but I don't think that occurs as far South as Ellura. So I had a quick look and I think it's C. pannosus which looks rather similar but a closer look matches its description."
