This dive site, Nurses Quarters, is situated approximately 1km west of Rottnest Island, Western Australia. It is renowned for its iconic "Shark Cave," which plunges to a depth of 26 meters from the main reef. The site also features interesting reef topography with various swim-throughs before reaching the main cave structure. Access to the cave is restricted to divers with specific training and certifications.
The primary draw of Nurses Quarters is the aggregation of Grey Nurse Sharks often found residing within the deeper sections of the Shark Cave. Beyond the main cave, the reef area and its swim-throughs are frequented by Port Jackson sharks and various wobbegongs, adding to the site's rich elasmobranch diversity. While not explicitly mentioned, a healthy reef ecosystem usually supports a variety of smaller reef fish and invertebrates.
While specific best times to visit are not detailed, Rottnest Island generally offers favorable diving conditions throughout the warmer months. Divers planning to explore the "Shark Cave" must ensure they possess the necessary advanced certifications for cave diving. Freedivers can enjoy the shallower reef sections and swim-throughs, where they may encounter Port Jackson sharks and wobbegongs, making it a versatile site for different diving disciplines.
