When we used to live in Cairns, we did on one occasion go water skiing in the inlet. Falling off was nerve racking to say the least (couldnt see your hand once it went under, so how you would see a croc I dont know). Why did we do this? Because our friends with the water ski boat and others were doing it from time to time and seemed to think nothing of it. After that first time, for us, never again in the inlet. But like a lot of other things we did over a period of years in FNQ, it was an experience (and once is enough). EDIT: Of course it didnt dawn until later......we had moved there from other (croc-less) places where we water skied for a bit of fun sport and to improve our slalom techniques, thinking nothing of falling off often through trying harder and harder to push the limits.....the locals virtually never fell off and were content to go for a water skiing "cruise" (which we never understood, except after you noted they/we were water skiing in croc infested waters......).
