SHARKS

Sharks and Humans - The chances of a shark attack are very low and there are some simple rules for safe swimming to apply to help reduce the risk of incidents involving sharks and humans:

• Always swim at a patrolled beach and between the flags.
• Leave the water immediately if a shark is sighted.
• Never swim alone.
• Never swim at dawn or dusk or at night.
• Never swim when bleeding.
• Do not swim in murky waters.
• Do not swim near schools of fish.
• Do not swim in canals or near a river mouth.
• Do not swim near, or interfere with, shark control equipment.
• Remember that sharks and other marine creatures are a natural part of the marine environment.
• The lifesaving patrols (and Shark Control Equipment where in place) are there for your safety, please swim only in patrolled locations.
