Meet the site
Providence Bay, Esmeralda Cove and Coal Shaft Bay make up the sheltered, camping-friendly side of Broughton Island, a striking contrast to the exposed, grey-nurse-shark-focused diving on the island's northern critical habitat sites. All three bays sit within the Broughton Island Nature Reserve, and Esmeralda Cove and Coal Shaft Bay in particular are popular, permit-required camping spots for boat-based visitors drawn by the island's pristine, largely undeveloped character and its clear, calm water in settled weather. As dive sites in the conventional sense they are modest — shallow sand and rock margins rather than the dramatic swim-throughs and aggregation sites the island is famous for — but they serve an important practical role for Nelson Bay charter operators as a sheltered fallback when wind or swell direction makes the northern sites too rough or dangerous to dive. For campers and private boat visitors, these bays are as much about the above-water experience — pristine beaches, clear anchorages and a genuine sense of remoteness only 20 km from Nelson Bay — as about anything found underwater, and casual snorkelling here reveals a reasonable but unremarkable mix of temperate reef fish and invertebrates typical of sheltered island bays on this coast. Divers specifically chasing Broughton Island's famous grey nurse shark encounters should not expect to find them in these southern bays, which lack the specific critical habitat features (gutters, caves, the Looking Glass passage) that concentrate the sharks on the northern side. They are, however, a worthwhile and scenic complement to a full Broughton Island day, whether as a lunch and swim stop between dives or a relaxed camping base for a multi-day visit by private boat.
