JAU-12
Why dive here
With 84+ marine species recorded in the area - including whale sharks and mantis shrimp - JAU-12 offers some of Cenderawasih Bay's richest wreck diving. Water ranges 27-31°C, warmest January, March, December.
JAU-12 is less a wreck dive and more a living museum, and we love it for that. This isn't about penetration or exploring pristine compartments. It's an almost entirely exposed hull, resting in just two metres of water, sometimes even less at low tide. We’re talking about a slow, deliberate snorkel or very shallow dive, allowing you to really absorb the history. Barnacle-encrusted metalwork, softened by generations of coral growth, creates these fascinating textures. You'll trace the line of the deck, imagining it in its prime, now home to clouds of reef fish darting amongst the shadows it casts. We often see juvenile blacktip reef sharks cruising nearby, and the occasional turtle grazing the algae. It’s a perfect site for photographers looking for unique shallow water compositions, or anyone who appreciates a quiet moment with history, without the pressure of depth or currents. Our top tip: go at high tide for the best visibility and a smoother surface swim.
