Explore South Australia
In terms of diving, South Australia is not as famous as states found to the north of the country - but there are hidden gems beneath the surface. The state covers some of the most barren areas of Australia and ,as such, is often overlooked. This means that it is relatively untouched and dive sites are quiet and peaceful. Whether based in Adelaide or more rural areas, there are memorable sites to enjoy.
There are plenty of dive centres to choose from, especially in large population hubs like Adelaide, Mount Gambier and Port Lincoln. Most of these offer all recreational dive courses, some have professional and technical qualifications too. There aren’t many dive resorts in this region, and no liveaboards.
The diving in South Australia is as varied as its landscapes. Mount Gambier offers some of the most unusual diving. The limestone topography of the region has led to multiple large lakes that are honeycombed with caves and caverns - perfect for trying out cave diving in crystal clear, blue water. Close to Adelaide are several good dive sites - famous Glenelg Beach has opportunities as does Rapid Bay, a 90 minute drive to the East. Port Lincoln, a 7 hour drive west of Adelaide offers some truly remarkable animal encounters. It is one of the most popular places in the world to cage dive with great white sharks. If you prefer your animals softer and friendlier, you can also dive with the local population of seals and sea lions! The tempestuous weather mean that the rocky coastline is littered with the skeletons of shipwrecks. Many of these can be dived and make for eerie explorations.

Diving in South Australia is possible year-round, though conditions vary by season. Water temperatures range from 11–15°C in winter (June–August) to 18–22°C in summer (December–February), so a thick wetsuit or drysuit is recommended in colder months.
Visibility typically ranges from 5–15 metres, improving in the cooler months due to lower plankton levels. Winds and swell can affect shore entries, especially in exposed areas. Spring and autumn generally offer the most stable and comfortable conditions for diving.
