23 kilometres southeast of the island, the world's tallest sea stack and the site of some of Australia's most remarkable diving can be found – the 551 metre tall Balls Pyramid. Exploring the caves and waters surrounding the basalt spearhead, divers come face-to-face with a mass of spectacular sea creatures.
From huge schools of violet sweep, rainbow runners and amberjack, to marlin, dolphin, turtles and wahoo, the underwater world will astound. Many rare species, like Spanish dancers and Galapagos whalers also make these waters their home. The Observatory Rock Sanctuary Zone is one of the only known places where the Ballina angelfish can be sighted while scuba diving.
The deeper waters around Balls Pyramid offer popular spots for local fishing charters.
