About Rottnest Island
Rottnest Island is a temperate Indian Ocean dive destination where limestone reef, caves, swim-throughs, and historic wrecks sit in clear water around sheltered bays and more exposed outer reefs. Divers usually visit by boat to follow the day's wind and swell, with sanctuary-protected marine life, stingrays, turtles, nudibranchs, wobbegongs, and other reef fish shaping the experience.
