Port Lincoln offers beginner divers the chance to get in the water alongside Australian sea lions and bottlenose dolphins in easy shallow conditions of 2 to 6 metres. The site is accessed by boat charter, and guided tours are available, which is genuinely useful here because visibility can vary considerably and currents are unpredictable. Keep an eye out for weedy sea dragons along the reef. The water is cold, so a good wetsuit is essential. Interacting with wildlife, particularly sea lions, requires a calm, respectful approach. Summer months from December through March offer the most reliable conditions.

Fishery Bay is a shore dive offering calm, shallow water that suits beginners well. The site sits along a reef where you have a genuine chance of encountering giant cuttlefish, octopus, seahorses, and cowfish. Dolphins occasionally pass through, and squid are also spotted here. Visibility can vary, so conditions are not always predictable, and a moderate current plus the possibility of surf and rip currents means you should check conditions before entering. Summer months from December through February tend to offer the most reliable diving. Basic facilities including parking and toilets are available on site.

Whalers Way Swimming Hole is a shore entry reef site on South Australia's remote southern coast, best suited to experienced divers comfortable managing surf entries and variable rip currents. Conditions shift without much warning, so solid situational awareness is non-negotiable here. The main draw is wildlife: Australian sea lions are the headline encounter, along with dolphins that move through on their own schedule. Sea birds work the surface above. Visibility is variable, so be prepared for anything from reasonable clarity to reduced sightlines. Best conditions fall between November and May, when calmer weather generally makes entry and exit more manageable.

Gunyah Beach is a gentle shore entry reef site well suited to beginners comfortable in shallow, calm waters. Visibility varies, so conditions can change between visits, but when it's clear you have a good chance of spotting weedy sea dragons picking their way through the reef, along with blue groper, flounder, seahorses, and a range of reef fish. Crabs and mud cockles turn up closer to the sandy patches. Dolphins occasionally pass through. The current is generally mild, making it manageable for newer snorkellers and divers. Be aware that sharks are present in these waters, and take care not to disturb marine life.

Yangie Bay Sanctuary Zone is a protected shallow bay that makes a welcoming introduction to snorkelling in South Australia. The calm, sheltered waters sit within a sanctuary zone, so the marine life here has had time to settle in and behave naturally around visitors. Seagrass beds cover much of the bay floor and provide habitat for crabs, cockles, and the occasional octopus tucked into the margins. Blue gropers and eels are regularly spotted moving through the grass, and sea stars are common finds for younger or newer snorkellers. Dolphins sometimes pass through the bay as well. Entry is straightforward from shore, with parking and toilets nearby.
