The Northern Beaches has five aquatic reserves which are an important part of the NSW system of Marine Protected Areas (PDF). Some of the benefits of marine protected areas are to:

  • protect and conserve the unique marine flora and fauna of each aquatic reserve
  • provide educational and research opportunities for students and scientists to learn about the marine ecology and management of the reserve
  • offer recreation and eco-tourism activities such as diving, snorkelling, kayaking and in some cases recreational fishing
  • create volunteering opportunities so community members can help protect the reserve and educate the rest of the community.

Marine Protected Areas are public places set apart for the protection of our marine animals and their habitats under the NSW Companion Animals Act 1998.

Please report illegal or suspect fishing activities to your nearest Fisheries Office or use the Fishers Watch Phoneline on 1800 043 536.
