12 Unique Underwater Wonders in Oceania for the American Diver

10. Lord Howe Island, Australia

Lord Howe Island sits like a postcard between Australia and New Zealand, encircled by a UNESCO-listed marine park. Its crystal waters boast more than 500 fish species and the world’s southernmost coral reef. The star attraction for advanced divers is Ball’s Pyramid—a towering, 1,800-foot volcanic stack that rises straight from the sea, home to Galapagos whalers, rare endemic species, and flourishing soft corals. Visibility regularly exceeds 100 feet, and the lack of crowds ensures a relaxed pace both on land and underwater. Strict visitor limits help Lord Howe retain its pristine quality, making every dive here feel exclusive. Many visitors extend their stay to hike, birdwatch, or enjoy the gentle island rhythm—a worthy sidebar to unforgettable underwater discoveries.
