Meet the site
One Bum Beach is the gentle counterpart to Barren Island's deep ledges: a small, sheltered fringing reef lying off a tiny beach on the island's protected side. The name is local humour about the size of the beach, and the dive is similarly compact, with the reef sloping from the beach to a sand edge at 6-9 m. The reef is built from plate, branching and boulder corals with patches of soft coral, and it is busy with small tropical fish: damsels, butterflyfish, wrasse, parrotfish and angelfish, plus the odd coral trout and sweetlips sheltering under plates. Turtles are often seen, and stingrays rest on the sand at the base. Because it is shallow, calm and close to the boat, One Bum Beach is the Keppel operator's choice for a relaxed second dive after Barren's deeper ledges or The Gulch, for divers doing training dives on a longer trip, and for photographers who want long bottom times in good light. The visibility is often better than at the inner islands because of Barren's outer position. It is not a dramatic dive, and experienced divers may find it quiet, but it is a pretty reef in good health that shows off the range of hard corals found in the eastern Keppels. It suits new Open Water divers, snorkellers staying on the boat, and anyone wanting a low-effort dive to finish the day. As with all the Keppel reefs, conditions on the day matter more than the site itself: after a run of calm weather the water off Barren clears noticeably, while a week of trade winds stirs up sediment even here. Take a torch to look under the plate corals, where cleaner shrimp and small cryptic fish shelter.
