Disturbing marine animals and habitat

Find out how you can protect our marine animals and their Western Australian habitats.

  Aquatic biosecurity

To help prevent the introduction of new pest species into Western Australia and to prevent those already here from spreading, regular vessel maintenance and effective antifouling is required.

Aquatic biosecurity is about protecting our oceans, rivers, lakes and dams from the spread of aquatic pests and diseases.

Find out more about good vessel maintenance, and what you can do to keep your vessel clean to make sure it won't be a biosecurity risk for Western Australia.

  Native marine animals

Please do not get close to our native marine animals, such as:

  • Sea lions.
  • Whales.
  • Dolphins.
  • Whale sharks.

Human presence could cause them to become distressed, especially if the mammals have young with them.

Whales and dolphins

Any marine vessel, whether powered by a motor, paddle or sail that is within a distance of 300 metres from a whale is within a whale's contact zone.

More information is available on the Department of Parks and Wildlife website.

  Crabbing restrictions to be introduced from 1st October 2013

New restrictions were introduced from 1st October 2013 for crabbers in the Canning River.

The restrictions have been developed to minimise any inconvenience between skiers, rowers and crabbers.

It is an offence to place crab drop nets in the restricted areas during the nominated times and offenders can be fined.

Please refer to the Canning River Crabbing Restrictions Boating Guide or contact DoT on 13 11 56 to receive a copy.

  Underwater habitats

Certain areas within our marine parks enforce 'anchoring prohibited' rules. This is because anchors could potentially damage the seabed.

Reefs and sea grass beds are vital habitats for a diversity of underwater creatures, and should be left alone.

If you need to drop anchor, look for a patch of sand amid the reef and sea grass, so as not to disturb the marine life.

If you have no choice but to anchor on reef, use a specialised reef anchor
