Big Sister's Island

Scheduled for completion by 2024, the enhanced Big Sister’s Island will serve the Marine Park’s objectives of conservation, outreach and education. Members of the public can look forward to a boardwalk, intertidal pools and a floating pontoon which will be sensitively established. Further inland, there will be forest trails for the public to explore.


Intertidal pools

Intertidal pools located along the inner sea walls create an environment similar to natural rock pools, providing additional hiding places for marine organisms, allowing visitors to view them up close during low tides.

Floating pontoon

A floating pontoon will be sensitively installed at Big Sister’s Island, adjacent to the jetty and looping back to the shore.

The pontoon will be specially designed to enhance biodiversity and provide opportunities for visitors to view marine life such as sea fans, sponges, sea anemones as well as hard and soft corals up close.

Visitors will also get to observe other mobile marine life through viewing panels on the base of the pontoons.
