Phil no salties but im pretty sure in some areas there are freshwater crocs .....nothing to worry about

. Most of the water systems/pools are swimmable except for a few areas near the Town of Wittenoom where Asbestos tailings from mining pose a hazard. When I went I visited the lookouts on the gorges instead of walking down into them because of the heat and the limited time I had out there.You really need to camp a few nights to appreciate the area, and to get to some of the pools/waterfalls require hiking to get there {and some climbing

.Like most scenic areas photographs/images dont do the place justice .
