About Never Fail Rock - GMI
Never Fail Rock - GMI is an exposed offshore pinnacle in Mercury Bay that suits advanced and expert divers who are comfortable in moving water. The pin is wrapped in sponges and soft corals, with open-water fish moving through the structure and larger pelagics showing at depth. Boat access is demanding because anchoring close to the rock is awkward and current can run from more than one direction, so settled conditions and a local skipper matter.
