Never swim with a wound that is bleeding. Don't urinate in the water. Do not swim in canals or near a river mouth. Avoid muddy waters. If a shark is sighted, leave the water.
Divers Follow the advice for swimmers.
If you see a shark, descend to the seabed, wall, bommie or other protection. Leave the area while staying close to the seabed or other protection. If you haven't dived for some time take a refresher dive with a Dive Master or local dive school before you visit the Reef. Practise in safe, shallow water before visiting the Reef. Be aware of strong currents around the islands.
