- ABOUT THE SPOT
Scuba Diving in Tumbledown Reef, South Head, New South Wales Australia
Apart from breathtaking views of the Sydney CBD and the Pacific Ocean, there are several excellent dive sites all along this section. The Tumbledown Reef is one of them. The spot is located outside of Sydney’s Harbor and north of the Gap.
The name of the dive site derived from a cliff section that collapsed and formed a large tumbledown of rocks. The maximum depth of the location is 20 m/65 ft and it can be dived in southerly winds. The visibility is good, around 10 m/32 ft.
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. Divers will most likely encounter old wives, blue and brown groper, leather jackets, some golden roughys and pigfish. At the sand line, divers can also expect to see numerous sponge gardens and sea fans. Last but not least, Tumbledown Reef is a good site for novice divers to experience open water dives. Note: book a boat dive in one of the many scuba schools located in the area.
