12 Unique Underwater Wonders in Oceania for the American Diver

11. Sipadan Island, Malaysia (Borneo/Oceania border)

While just outside strict Oceania geography, Sipadan belongs on many American divers’ Pacific itineraries. This volcanic island off Borneo is famed for scenes straight from a diver’s dream—barracuda tornadoes, whirling jackfish, and a resident population of green and hawksbill turtles. Its steep reef walls drop into the abyss, teeming with swarms of bumphead parrotfish and prowling reef sharks. Strict daily permits keep visitor numbers low, preserving both exclusivity and ecological health. Fast-paced drifts and pristine coral gardens challenge and reward divers at every turn. Those lucky enough to secure access report life-long memories and dramatic underwater photo ops. For U.S. travelers seeking pelagic-packed action and a chance to explore rare reef ecosystems, Sipadan stands out as a high-priority goal.
