The reserve is a no-take area, meaning it is illegal to touch, feed, or remove any plants or animals, including shells.
It is home to the blue groper, a large, inquisitive fish species that is the state fish emblem of New South Wales.
The aquatic reserve serves as a critical habitat for the endangered Little Penguin colony that nests in the nearby North Head area.
Surveys have recorded over 160 different fish species within the relatively small 20-hectare reserve boundaries.
The underwater terrain features the 'Cabbage Tree Bay' rocky reef, which provides essential shelter for various invertebrate species.
Cabbage Tree Bay Aquatic Reserve is a 20-hectare marine sanctuary located between Manly Beach and Shelly Beach in Sydney. The reserve is a no-take zone, meaning all marine life is protected, and fishing or collecting of any kind is strictly prohibited. The seabed comprises a mix of rocky reefs, sandy bottoms, and seagrass beds, supporting a diverse array of over 160 species of fish. It is a premier site for snorkeling and scuba diving due to the high visibility and proximity to shore. The area is managed by the New South Wales Department of Primary Industries to preserve biodiversity. A paved path, the Marine Parade, traces the coastline, offering vantage points for observing aquatic activity from above. During the summer, the waters attract visitors looking for sightings of blue gropers, wobbegongs, and occasionally turtles or penguins. The reserve serves as an educational site for marine research and habitat conservation.

Bring polarized sunglasses to reduce glare on the water surface when viewing marine life from the coastal path.
Check local tide tables; snorkeling conditions are best during high tide when visibility is typically higher.
Use eco-friendly sunscreen to avoid introducing chemicals into the sensitive marine environment.
Do not attempt to walk on the protected rock platforms during low tide, as this disturbs sensitive organisms.
No fishing, no collection of shells or marine life, and do not feed the fish. Stay on marked paths when walking along the shore.
