Pool of Siloam is a shallow shore dive on the Fleurieu Peninsula, reaching a maximum depth of 6 metres. This site is suitable for beginners, though divers must be prepared for cold water temperatures ranging from 14C to 17C throughout the year. The water is seven times saltier than the ocean, creating extreme buoyancy that requires careful weight management. Divers should be aware of variable currents and potential changes in visibility. Facilities at the site include parking, toilets, showers, and changing rooms. Night diving is permitted at this location.

Post Office Rock is a shallow reef dive located on the Fleurieu Peninsula, suitable for beginners. Accessed directly from the shore, the site features a reef structure with sandy patches, crevices, and sponges. Divers should be aware of shifting currents and variable visibility, which is best following a period of calm weather and at high tide. Water temperatures range from 14C to 17C, requiring appropriate exposure protection year-round. The habitat supports a variety of temperate marine life, including reef fish, invertebrates, and various rays and sharks common to the region. Hazards include the presence of sharks and rocks in the area.

Fossils Cave is a freshwater sinkhole dive featuring embedded fossils of extinct megafauna within the cave walls and substrate. This site is strictly for expert divers due to the overhead environment, which requires full cave training, appropriate redundancy, and the use of a guideline. The average depth is 13 metres, with a maximum of 16 metres. Visibility is typically 40 metres, though the dark silt on the bottom can be easily disturbed. Water temperatures remain cold, ranging from 14C to 17C throughout the year, necessitating the use of a drysuit. There is no current, but the overhead environment demands careful gas planning and decompression management.

Tank Cave is a complex freshwater cave system located in the Mount Gambier Sinkholes. This site is strictly for divers with full cave certification, as it is an overhead environment featuring a maze-like layout. Divers typically reach depths of 15 to 20 metres, with visibility ranging from 20 to 30 metres. The water temperature remains constant between 14 and 17C throughout the year. Due to the risk of silt-out and entanglement, this site requires meticulous navigation and redundant lighting. Access is via the shore, and divers should confirm current permit requirements and site restrictions before arrival.

Pine Cave is a technical freshwater cave dive located in the Mount Gambier Sinkholes. The system features depths ranging from 25 to 40 metres, requiring full overhead environment training and rigorous decompression planning. Divers enter from the shore to explore the cave, where visibility typically fluctuates between 10 and 30 metres. The environment is static with no current, though the lower levels are prone to silting. Divers must maintain strict buoyancy control and line discipline to manage entanglement risks. The site is suitable for experienced technical divers only. Parking is available at the entry point.

Carpenter Rocks is a beginner-friendly reef dive located in South Australia. The site features a reef structure ranging from 8 to 12 metres in depth, making it suitable for divers building confidence. Divers can expect mild currents and visibility between 5 and 10 metres. Water temperatures at this site fluctuate between 14 and 17 degrees Celsius throughout the year. Access to the site is by boat, and it is recommended to confirm boat operator availability locally before planning a trip.
