Yes - really good photo. Tugg Hill looks very suitable for reptiles although i suspect it had a bit of a flogging back in the livestock grazing era. There are huge former sheep camps up on the main hill tops. A lot of rocky areas. It would be great to get more photos of reptiles from the reserve.
Tuggeranong Hill lies on the boundary of the former Tuggeranong and Lanyon Homestead properties. Despite there being heavy grazing in the past, parts of the reserve have exceptionally good woodland native flora remnants, as good as the best in ACT.
