you name it, we got it this time of year, irukandji, chironex, tamoya jellyfish, stingrays, tiger sharks, stonefish, crocodiles, thunderstorms and cyclones!
My advice is....wear you stinger suit and don't fall in, and if you do fall in, get back up quick, and if you can't get back up quick, then for faaarks sake don't put your feet down on the reef!
..look on the bright side...you'll get better really quick! (I went from bodydragging to riding upwind in 1 session

)
nah, just talking it up mate, you'll be fine, we run our snorkelling ecotours right through summer and we haven't lost a punter yet. I can sort you out for a lycra suit, just give me a call.
