Marine Pests

Introduced or exotic species that are not native to Australia may become established around Mosman and become marine pests affecting the environment and our enjoyment of the coast.

Caulerpa Taxifolia

The marine pest Caulerpa taxifoli has been identified in areas of Balmoral, Chinaman’s Beach and Chowder Bay. This pest is not known to affect human health but can spread rapidly and potentially alter marine habitats.

Stop the Spread of Marine Pests

  • Inspect anchors, ropes and other gear for marine pests.
  • Inspect fishing equipment; nets, traps and fishing lines before use.
  • Inspect dive gear such as wetsuits bags and other equipment before use.
  • Collect fragments of Caulerpa taxifolia and other pests you have accidentally picked up. Seal in a plastic bag and dispose of in a bin where they can not re-enter a waterway.

Any sightings of suspected marine pests should be reported to the NSW Department of Primary Industries 24 hour reporting hotline: 4916 3877.
