Long Reef Aquatic Reserve is the oldest aquatic reserve in NSW. It was declared in 1980 to conserve the diversity of seashore plants, animals and habitats.
The reserve is an important place for marine education and research. Thousands of schoolchildren and university students visit each year to study the marine animals and plants conserved here.
The reserve covers an area of approximately 80 hectares. Its boundaries extend along the shore from Collaroy rock baths south to Long Reef Surf Lifesaving Club and out to 100 m offshore.
The traditional custodians of this area are the Garigal people and the Gannagal (also known as Cannagal) people of the Eora nation.
