At the far end of visibility along the reef wall, an unmistakable triangular silhouette with a bright white underbelly appeared – a tiger shark rising confidently towards me. This is one of their known favourite hunting techniques. The four-metre shark kept coming, until eventually it was within arm’s reach, and bumped against the dome port of my camera.

The vast waters of Asia and Oceania conceal some of the world’s most extraordinary technical diving sites, where history, geology, and marine ecology converge in the deep blue. From wartime wrecks resting at extreme depths to cathedral-like cave systems and walls that plunge into the abyss, this region offers technical divers training experiences that push both skills and equipment to their limits. These are not sites for the recreational diver; they demand advanced training, meticulous planning, and a clear respect for the risks inherent in venturing beyond conventional depth limits. For the prepared and well-trained diver, however, the payoff is true exploration.
