I'm pretty certain he's OK. None of the scars seemed very recent and all healed without any signs of septacemia (closest i could get to correct spelling, hope you know what i mean).
I was thinking a cunningham's skink when I initially saw the picture.
Regardless what species it is- that guy is like the Rambo of the reptile world
Ben.
Iam not much of a skink man but its not a cunningham or egernia striolata maybe a juvenile egernia frerei Rossagon but not sure i have only seen a couple of adults...someone should give a postive id soon.
Cunningham's skinks have spiky scales (especially on their tails). The scales of the pictured animal look smooth to me. I agree with Rossco - it looks like a young major skink (Egernia frerei). In fact, I'm 100% certain of that.
