1Ball's Pyramid
Lord Howe Island, Lord Howe Island
The world's tallest sea stack, 26 km offshore, surrounded by pelagic fish in open ocean.
It rises 562 metres out of open ocean with nothing else around it, and the underwater experience matches that drama — sheer volcanic walls dropping into blue water, with large fish schools concentrating on the only structure for kilometres.
Look for: kingfish, amberjack, trevally, rainbow runners, large fish schools
