Conditions vary, and the site is best suited for those who can manage current. Parking is available at the shore access point. Divers should enter when the current is at its slackest to ensure a safer experience.

Olivers Reef at The Bluff is a shallow shore dive with depths ranging from 1 to 5 metres. The site features a reef structure with holes that can create significant surge and moderate currents.

Myponga Beach is a shore-accessible reef and wall dive located near Rapid Bay Jetty. The site features shallow depths ranging from 0 to 5 metres, with an average of 4 metres, making it suitable for beginners.

Facilities available on site include parking, toilets, showers, changing rooms, and a cafe.

The HMAS Hobart is a 133-metre destroyer scuttled in 2002 to serve as an artificial reef. Resting upright on the seabed, the wreck spans depths of 5 to 30 metres with an average depth of 17 metres. This site is strictly for advanced divers due to strong tidal currents and potential overhead environments within the superstructure. Penetration requires specific wreck diving certification to manage risks like silt-out and disorientation. Visibility fluctuates between 0 and 20 metres. Access is by boat only, and a permit is required. Divers must plan for slack tide to mitigate current strength and carry essential safety equipment including a torch and surface marker buoy.
