Looks like a Two-lined Dragon Diporiphora bilineata[/i ] to me but this is quite a diverse and complex group of similar looking species and I'm very out of touch with things so best to wait for someone who is more familiar to give you confirmation.
is that you with the drilling rig?...you must get to see some nice country off the normal tracks!
bit hard to tell from the pic, but looks very similar to this one 1st pic D. Austalis
although, like Saratoga said they are a very close and complex group.
2nd pic is D.Bilineata
The animal in the picture is a male Nobbi Dragon. Species is Amphibolurus nobbi. I have several of these in my collection. It is not D.australis or D. bilineata, both of which I also keep.
