The Big and Little Brother Islands are the first B in this triangle. Undersea mountains that rise from the surface are part of Marine Park Islands National Park. These islands offer breathtaking wall diving, with an amazing variety of fish like barracudas, tuna, and snapper, as well as occasional hammerheads and silky and whitetip sharks. Sometimes even manta rays can be seen here. The diversity of soft corals and gorgonians that cover the wall is incomparable. The Brothers Islands also offer wreck diving. Aida and Numidia lie along the walls of Big Brother. Once a supply vessel and a cargo ship, they are now home to a thousand fish. Daedalus Reef is also a part of the Marine Park, which is a lighthouse reef with deep walls and drop-offs and is known as a place where divers have a chance to spot scalloped hammerhead sharks. The last but definitely not least part of the triangle is Elphinstone. This destination is famous for drift dives with breathtaking deep walls encrusted with corals. Oceanic white tips, hammerheads or reef sharks may be in this area
