Boullanger Island in Jurien Bay offers shallow diving and snorkelling across seagrass beds and reef structures. Depths range from 1 to 6 metres, providing an accessible environment for beginners. Access is by boat only, with the site located 1000 metres from the shore. While the area features sheltered anchorages, afternoon sea breezes during summer can create surface chop. The reef supports diverse habitats including sponges, sea fans, anemones, and corals, alongside western rock lobsters, octopus, and cuttlefish. Divers and snorkellers should remain aware of the presence of sharks and lionfish in the area. Sea lions are also present and require visitors to maintain a respectful distance.
