North (Sydney) Harbour Aquatic Reserve is located between North Head and Dobroyd Head in the northern part of Sydney Harbour, covering an area of approximately 260 hectares.
Historically, the reserve was the site of some of the first marine specimen collecting conducted in the 1830s by the superintendent of the Quarantine Station.
The aquatic reserve includes a variety of habitats, including rocky shores, sandy beaches, nearshore reefs, sandy seabed and harbour waters up to around 20 m deep.
Sheltered coves contain seagrass habitats and nearshore reefs support kelp habitats that are used by many species, including seahorses and sea dragons. The rocky reefs and kelp beds are also home to many different invertebrates and fish and the boulder habitats in deeper waters are inhabited by colourful sponges and corals. In summer, tropical fish are a common sight, carried from the Great Barrier Reef along the NSW coast by the East Australian Current (EAC).
An area of critical habitat for the little penguin is located within the reserve.
You can enjoy many marine activities such as snorkelling, scuba diving, swimming, boating and line fishing. You can line fish for finfish only (fish with a backbone), subject to other NSW fishing rules and regulations.
Spearfishing is prohibited.
No invertebrate animals, cunjevoi or marine plants (whether alive or dead) can be taken or collected from this reserve. This means that you cannot collect shellfish, fish for squid or cuttlefish, collect any marine animals or plants from the shore, pump for worms or collect empty shells (because they provide important homes for living organisms).
Other than finfish, no marine animals or plants can be harmed in the reserve.
Avoid anchoring in seagrass beds to help protect this important fish habitat.
