Snorkelling at Port Noarlunga

Diving and snorkelling in South Australia

Explore South Australian waters. They offer some of the most pristine and diverse diving experiences in the world.

Friendly or frightening

Australian sea lions are a rare species so take the opportunity to swim with them at Baird Bay on the Eyre Peninsula. These animals are naturally curious and often swim right up to divers. Can’t somersault? Learn from the pros.

The more adventurous among us can cage dive with great white sharks near Port Lincoln. These sharks grow up to six metres long and can weigh as much as 3,000 kilograms. Get up close and feel the thrill when one swims past. 

Dive with friendly sea lions

Some great places to see our friendly sea lions are Kangaroo Island, Eyre Peninsula and the Fleurieu Peninsula. 

Cuttlefish and leafy sea dragons

Snorkel with giant cuttlefish near Whyalla. Watch as they change colour and texture to blend in with their environment. Whyalla is the cuttlefish capital of the world. The annual spawning season is from May to August.

Spot leafy sea dragons and weedy sea dragons. These fascinating creatures are close seahorse relatives. They only live in southern and western Australian water. Find them around Yorke Peninsula, Kangaroo Island and the Fleurieu Peninsula. 

Wreck dives

Dive down to a shipwreck. The ex-HMAS Hobart is one of Australia’s best. Most of the ship is intact and divers can explore engine rooms, mess decks and gun turrets. It’s only a 10 minute boat ride from Marina St Vincent on the Fleurieu Peninsula. 

Off the coast of Port Willunga is the Star of Greece wreck, which is more than 125 years old. The Star of Greece restaurant is named after the ship with gorgeous views looking out over the ocean.

Experienced divers can explore Troubridge Shoals off Yorke Peninsula. It's home to several ships that were wrecked in the nineteenth century. It’s crawling with spider crabs and other marine life making the shoals a delight for divers and underwater photographers. 

Follow the Trail

The Port Noarlunga Aquatic Reserve, incorporating the Port Noarlunga Reef, was the first aquatic reserve proclaimed in South Australia. The Reef, 400 metres off shore and about 1.6 kilometres long, is home to more than 200 marine plant species and over 60 fish species, making it popular with snorkelers and divers. Explore the fantastic self-guided diving trail.

There are two underwater Maritime Heritage Trails off the Yorke Peninsula. The Wardang Island Maritime Heritage Trail includes 8 wreck sites. The Investigator Strait Shipwreck Trail highlights 10 vessels wrecked in the region.

On the surface

Scuba divers aren't the only ones who'll have fun. There’s also great snorkelling. See schools of fish and leafy sea dragons at Rapid Bay jetty or snorkel the reef at Second Valley. Both areas are within the Encounter Marine Park.

The pristine waters of the Yorke Peninsula offer some state’s best snorkelling spots. Find fish, seahorses and coral around Edithburgh jetty. See Port Jackson sharks and eagle rays around Point Gilbert at Port Moorowie or snorkel at the Parsons Beach reef.
