Pool of Siloam is a shallow shore dive in South Australia, sitting in easy waters no deeper than 6 metres. This makes it a comfortable option for beginner divers getting familiar with conditions in the region. Visibility here is variable, so some visits will offer clearer views than others. The site is home to water plants, which are worth taking a slow look at as you explore the shallows. Come prepared for cold water, as temperatures can be bracing. Current is variable too, so check conditions before you get in.

Post Office Rock is a shallow reef dive accessed directly from shore, making it a solid choice for beginners getting comfortable in South Australian waters. The site sits in calm, shallow conditions, though visibility can vary depending on swell and recent weather, so picking a settled day matters. Currents shift here, so check conditions before you get in. Underwater, you can expect to find fish moving through the reef structure, seahorses tucked among sponges, rays resting on the sandy patches, and crabs working through the crevices. Cold water is the norm, so a good wetsuit is essential.

Fossils Cave is a cave dive offering something genuinely rare: embedded fossils of extinct megafauna visible in the cave walls and substrate. Visibility holds at 40 metres in crystal clear water, and depths run 13 to 15 metres, but the overhead environment demands full cave training and appropriate redundancy before you consider entry. There is no current to contend with, but entanglement risks and the requirement for decompression planning mean this is strictly expert territory. The site also shelters rare crustaceans of the genus Koonunga, a find that few divers ever encounter. Cold water throughout the year calls for a well-fitted drysuit.

Tank Cave is a submerged freshwater cave system in South Australia that demands full cave diving certification and a serious respect for overhead environments. Depths run from 15 to 20 metres, with visibility ranging from 10 to 30 metres depending on conditions within the system. There is no current to manage, but the hazard list is substantial: narcosis, entanglement risk, decompression considerations, and the ever-present reality of diving beyond daylight. The draws are genuinely unusual: stygofauna adapted to perpetual darkness, and fossils embedded in the cave structure. This is a site for divers who treat penetration diving as a discipline, not an adventure.

Pine Cave is a technical cave dive in South Australia requiring full overhead environment training, decompression planning, and appropriate gas management before entry. The system runs from the surface to 40 metres, and visibility between 10 and 30 metres means line and light discipline still matter regardless of how clear conditions appear. No current works in your favour here, giving you time to move methodically through the cave. Entanglement risks are present, so buoyancy control and staged penetration are non-negotiable. Glenelg Spiny Crayfish inhabit the cave and reward patient, unhurried divers who take time to scan the walls and crevices.
