I'm not sure why you think it is nobbi. They can be difficult to tell from muricatus from a photograph and the most convincing features that would help determine a nobbi id would be a pink colour inside the mouth rather than the bright yellow of muricatus or a reddish pink flush to the base of the tail in an adult male. This individual seems to be a juvenile. What do others think?
I agree with John - this is A. muricatus. Nobbi dragons are not found that high up in the mountains. The nearest location to your record where they occur is the very lower slopes of Mt Tennant (along the first km of the walking track to the west of the Boboyen Road in and near dry open rocky Callitris woodland). However it is good that you checked in with the record - it is quite a high elevation record for muricatus so really useful. There is something about that Clear Range area....... especially with all those Rosenberg Monitor records. WillO.
