Barrenjoey Head Aquatic Reserve
Barrenjoey Headland Aquatic Reserve includes the entire rocky platform around Barrenjoey Head - from the northern end of Station Beach to the northern end of Palm Beach - and extends 100m seaward from mean low water.
The rock platform is about 2000 metres long, with the headland at the junction of the Hawkesbury River and the ocean.
The surrounding Ku-ring-gai Chase National Park provides a degree of self protection and contributes to making the aquatic reserve an area of great natural beauty.
What you can do in this reserve
Line fishing and spearfishing (subject to normal restrictions) are permitted in the aquatic reserve. Collection of rock lobster, sea lettuce and baitweed is also allowed.
To protect a range of marine species and habitats in the reserve the following activities are prohibited:
•the collection of cunjevoi, commonly used as bait, and all invertebrates (dead or alive), including anemones, barnacles, chitons, cockles, crabs, mussels, octopus, pipis, sea urchins, sea stars, snails and worms, and empty shells
•the taking of abalone in line with a general ban between Port Stephens in the north and Wreck Bay Beach, Jervis Bay in the south.
