How do I reduce the risk a shark interaction?

The risk of shark attack is extremely low. Take the following steps to minimise the risk of human and shark interactions.

Avoid swimming near potential food sources

Do not swim where there is a possible attraction or food source for sharks.

For example, in areas where there are:

  • large schools of fish
  • pods of dolphins
  • seals
  • sea lions.

Avoid swimming and scuba diving in water:

  • that is being used by recreational or commercial fishers
  • where there are signs of bait fish or feeding activity.

Do not enter or remain in the water if you have open wounds or are bleeding.

Avoid having pets in the water with you.

Avoid shark habitats

Do not swim in:

  • murky waters
  • near a river mouth, after heavy rainfall
  • in deep channels
  • between sand bars or steep drop-offs.

Avoid swimming in the water at dawn, dusk or at night. Some species of shark are known to come inshore at these times to feed.

Do not enter the water if large sharks are known to be present.

General advice

  • Do not swim alone or too far from shore.
  • Always swim at patrolled beaches and stay between the flags.
  • Look carefully before jumping into the water from a boat or jetty.
  • Leave the water if schooling fish or other wildlife start to behave erratically or congregate in large numbers.
  • Refrain from excessive splashing.

What should I do if I encounter a shark?

If you come across a shark, do not to interact with it.

If you see a shark whilst swimming leave the water as quickly and calmly as possible.

If you are in a small boat or paddle craft return to shore. If it is not safe to do so, get assistance from a nearby fishing vessel.
