We have goannas all over the country, including the southern parts. You just head out into the bush and make sure you don't step on any snakes and then look for the lizards. And avoid perentie goannas. One of the guys in ANGFA got bitten by one and it took a long time to heal and he was on antibiotics during most of that time. Apparently they have hundreds of undescribed species of bacteria in their mouth and if they bite you, it will get infected.Yeah I know everything in Australia wants to kill you. I would still love to visit and go to Kakadu to find some goannas.
Aside from that it would be cool to have a fishing spider in an aquarium and watch it underwater with it's little bubble of air.
