New to Oz; hope you don't get sick of me looking for help. I assume these are all common skinks around these parts but just wanted to check. The first was on a cement barrier in Coogee, the second was in Kamay Botany Bay National Park in some leafy ground-cover, the last two were in sandstone outcrops on the coast of the eastern suburbs. My guesses are: Cryptoblepharus pulcher, Lampropholis guichenoti, and Eulamprus quoyii x 2
