I heard a news brief that said the Ausies have made a shark repelent that straps onto the ankle and gives off an electrical field which make sharks more and more uncomfortable the closer they get to the diver wearing the device. HMMMMMMMMMMMM, hope no-one uses the device and finds out that you don't want a really uncomfortable (really pissed-off) shark next to you. ;)
