Boullanger Island offers easy, shallow diving across seagrass beds and reef in just 1 to 6 metres of water, making it a genuinely accessible site for beginner divers. Visibility is variable, so conditions can change, but the mild current keeps things manageable. The real draw here is the marine life: Australian sea lions and dolphins occasionally pass through, while the reef holds western rock lobsters, octopus, cuttlefish, sponges, sea fans, anemones, sea squirts, and tropical corals. Keep an eye out for lionfish among the reef structure, and give them a wide berth. Access is by boat charter only.
