Michael I have not looked into what kinda shots we would need for Australia. There is no "guide" really. The purpose of the trip is to work with researchers there on McKinlay River catching freshwater crocodiles to determine the effect the cane toad is having on their population. Dr Adam Britton is the person who will be in charge there and basically we will be working under his supervision.
No experience is necessary for this trip... just be willing to work hard and long and don't expect too much sleep at night. I have talked to some people who did this before and they really enjoyed the experience.
