The rebreather portal facilitates rebreather dedicated expeditions to one of the most extraordinary deep dive locations in the Coral Sea. Undersea Explorer based out of Port Douglas, operates rebreather dive expeditions to Osprey Reef. These expeditions to the remote Osprey Reef which offers incredible visibility and extraordinary 1000 metre deep vertical walls. Undersea Explorer has the most experience of visiting Osprey Reef and a long history exploring the area. At North Horn, Osprey Reef, where the currents meet, you'll see large schools of tuna, barracuda and plenty of sharks - white tips, grey and silver tip whalers, leopard sharks, thresher sharks and schooling hammerheads. You'll dive with groups of Manta Rays, and be privileged to photograph the rarely seen nautilus.
