Rowley Shoals: Australia's Best-Kept Secret

On the opposite side of Australia from the Great Barrier Reef lies Rowley Shoals, one of the ocean's largest unspoiled coral reefs, with more than 200 species of coral and 600 species of fish. Formed by three pear-shaped atolls, the remote reef is one of few in the world affected by dramatic 16-foot tides, which push huge amounts of seawater in and out of the coral lagoons, creating a seascape like something out of Posiedon's very own underwater world.

The fish couldn't have been more hospitable, inviting us right into their homes — like this potato cod who was attracted to my pink goggles and followed me around lilke an underwater puppy. | Jezza Tucker

Sailfish, marlin and sharks, oh my! We saw fish that could star in a Disney movie and those that would've given Jaws some competition. Big-game fishing is a thrill out here. | Jezza Tucker
