Descend into living history on rarely-dived WWII Japanese shipwrecks draped in hard coral and patrolled by reef sharks. Cenderawasih's isolation has kept these wrecks spectacularly intact — a bucket-list dive for any serious underwater explorer.
What to expect
Calico Jack's guides lead you down to Japanese transport and naval vessels that sank during Pacific theatre engagements, now festooned with sea fans, black corals, and enormous schools of glassfish. Penetration dives into cargo holds reveal wartime artefacts preserved in extraordinary condition thanks to minimal diver traffic. Surface intervals are spent drifting over pristine reef gardens, spotting pygmy seahorses and wobbegong sharks resting in the shallows. Two to three dives per excursion day is standard, with full kit and Nitrox included.
