I'm using Cogger's humongous book/paperweight for the bulk of my identifications. It doesn't even list the two Amphibolurus species you mentioned, nor the S. roperi. Do you have a reference I can pursue in that respect?

>>The skink is Carlia amax

Doesn't look like the picture in Cogger, but if that's the prevalent ground skink in Kakadu, I'll take your word for it.

>>Your "Varanus panoptes looks more like Varanus mertensi

I admit that the coloration is not what I would've expected from panoptes, but the habitat and location was WAY off for it to be mertensi.

and I one shot of the "Varanus scalaris"..looks more like Varanus tristis orientalis.

Well, that one I am really undecided on!
