South Head is the southern headland of the entrance to Sydney's Harbor, at the north of the suburb of Watsons Bay. Hornby Lighthouse, the third oldest lighthouse in New South Wales, is located in South Head.
Apart from breathtaking views of the Sydney CBD and the Pacific Ocean, there are several excellent dive sites all along this section. Located on the south of the Gap and on the west of Sydney’s Harbor, Diamond Bay is a reef that drops from 16 m/52 ft to 22 m/72 ft.
The most amazing part of this dive site is found around and under the boulders where divers can see a significant number of fish, such as giant cuttlefish, rays, weedy sea dragons, wobbegong, moray eels and hawkfish. Diamond Bay is considered to be an easy dive with good visibility. Water temperature is up to 21°C / 69.8°F in summer and early autumn months and between 14-18°C / 57.2-64.4°F in winter.
Note: book a boat dive in one of the many scuba schools located in the area.
