Found these critters while @ work can someone shed some light on what they are as Lizzies aren't really my thing? Although these were both really cool in that they alowed me up really close. The little fella sprinted on his back legs for ages B4 coming to rest.
2nd and 3rd i would day Varanus Gouldii Flavirufus because of its patterning. Normal Gouldii Gouldii's generally dont have nice patterning like that. The first i would say it would be some sort of Lophognathus.
