Jack Daniels is a boat-access reef off Tufi in Papua New Guinea, reached as a long outer-reef run from the nearby resort. The site is a sloping wall with healthy coral, strong tropical visibility, and the kind of shark, ray, turtle, and pelagic life that makes the area feel remote and alive. Expect warm water and light to moderate current, so this is best treated as a guided reef dive rather than a casual hop-in.
