I own 1 central bearded dragon, 1 eastern bearded dragon, 1 eastern water dragon and 1 eastern blue tongue skink.
In herping around Rocky I've found countless skinks, 3 browns, dozens of water dragons, dozens of Fitroy River turtles, 1 green tree snake, 2 lacies, a few leatherback sea turtles, and heaps of snake skin bits.
I've found the place for water dragons is the Kershaw gardens, on the Tropical Rainforest walk. The best for seeing pythons is out near the Etna Creek area. One crawled up into a friends motor bike while he was at work in the gaol! The officers luckily caught it on CCTV and went out to get it from the bike. Took them a few hours as he was snappy and BIG! I've also got a bandy bandy hatchling from there, and my Mum ran over a python (didn't hurt it, she ran OVER the top of him) while coming home one night.
Hmmm, let's see. Best place for turtles is down near the barrage.
Mt Archer is pretty good for browns, and the BErserkers are just crawling with taipans, apparently.
Bifield is great for tree snakes and lacies and water dragons too.
And I've found hundreds of beardies off of Berserker Street near the stables.
