Rottnest Island

The next beautiful name on the list of the best dive sites in Australia, Rottnest Island, is only a short ferry ride away from Perth. With unique wildlife such as quokkas and excellent cave and wall diving, this small limestone island is one of Australia's most popular dive spots. Most visitors come to Rottnest Island to see quokkas, one of Australia's cutest marsupials, but divers should consider paying a visit to this picturesque island off the coast of Perth to see a unique wobbegong shark.

Historic shipwrecks, swim-throughs, and an abundance of marine life can all be found on Rottnest Island. In addition, this limestone continues to form caves, cavities, and ledges beneath the surface, resulting in some of Australia's most fascinating dive sites. At the aptly named Shark Cave dive site, expect to see barracudas, groupers, wobbegong sharks, and numerous nurse sharks. While you are there, you might even see a passing humpback whale.
