Why dive here
With 199+ marine species recorded in the area - including blue sharks, bull sharks, dolphins, dugongs and great white sharks - Slot Cave offers some of Sydney & New South Wales's richest cave diving. Water ranges 18-23°C, warmest January, February, March.
Slot Cave is an intriguing site offering a genuine cave experience. We drop in on the ocean side, then swim through a narrow slot that opens into a large cavern. You’ll find wobbegongs and the occasional grey nurse shark sheltering inside. It’s a dive best suited for those comfortable in overhead environments.
Safety Notes
Overhead environment - never enter without proper cave/cavern training, redundant equipment, and a guideline.
