Discover the Underwater World of Rottnest Island

Divers and snorkelers visiting Australia tend to think of Queensland's Great Barrier Reef as the place to be. Well, you'd think that, wouldn't you? I did.

In fact, you can find good diving and snorkeling spots all along the Australian coastline and off the many Australian islands.

Many diving sites can be found in Western Australia, and Rottnest Island just across the water from Perth has been drawing divers and snorkelers to the diversity of fish and coral species in and around its numerous reefs.
