Chinaman's Hat is a South Australian reef dive defined by its cave systems, seagrass beds, and a current that demands attention and respect. Depths run from the shallows to 15 metres, giving you room to work with, but the moderate to strong current means you need solid buoyancy control and the ability to abort a dive cleanly. Visibility is variable, so conditions can shift considerably between visits. The marine life rewards the effort: Port Jackson sharks and wobbegong sharks rest on the bottom, blue devil fish hold territory around the reef structure, and fiddler rays, morwongs, eagle rays, nudibranchs, and rock lobsters fill out the picture. Australian fur seals and dolphins appear occasionally.

Dolphin Bay is a shore dive where the main draw is straightforward: dolphins. The site offers shallow, calm waters, making it approachable for beginner divers and snorkellers who want a genuine wildlife encounter without complicated logistics. Visibility here is variable, so conditions can differ from visit to visit. The current is generally mild, though a rip current can develop, so always check conditions before entering. Entry is direct from shore, and parking is available on site. The best time to visit runs from November through to March, when summer conditions tend to be at their most favourable.

Blue Pool at Shell Beach is a calm, shallow entry point that suits first-time snorkellers and those looking for a relaxed underwater explore. The sheltered conditions mean no current to contend with, though visibility can vary depending on the day. Keep your eyes close to the reef and you will find small fish weaving between coral, shell anemones, crabs, and the occasional octopus tucked into a crevice. Watch where you place your hands and fins, as the coral is sharp and some marine life will respond if disturbed. The site is best visited between November and March.
