Our pristine coastline extends over 31 kilometres from O’Sullivan Beach to Sellicks Beach. The clear gulf waters attract beachgoers for many different activities including swimming, surfing, sailing, walking, snorkelling and beachcombing.

The surf offers a variety of conditions. The gentle beach breaks suit novice surfers while Southport, Trigg Point, Seaford, Gull Rock and Moana offer more challenges for experienced surfers. The south coast attracts swimmers, surfers, divers and boaties. Notable dive spots include the Port Noarlunga reef and the Aldinga ‘Drop-off’. Our clear southern waters are home to many unique species of marine life such as the leafy sea dragon.

Local beaches

O’Sullivan Beach

With a boat ramp, good swimming and breakwaters providing protection for fishing boats and fish, O’Sullivan Beach is a beach that provides you with all you need.

Christies Beach

Witton Bluff provides swimmers with shelters at Christies Beach. Divers can explore the nearby reef. The foreshore picnic area and nearby shopping precinct all add to the attraction of Christies Beach. 

Port Noarlunga

The picturesque steep red sandstone cliffs of Port Noarlunga and long jetty provide visitors with a scenic walk and a place to fish. The Port Noarlunga reef and aquatic reserve are recognised as a popular diving location; they also shelter the beach from large waves.  

Southport

Southport is popular for beach fishing and surfing. Regular surf lifesaving carnivals are also held at Southport. 

Seaford

Very popular with surfers, Seaford offers more than just waves. From the extensive walking/bicycle trail along the cliff tops, you’ll have a magnificent view of the coastline. 

Moana

Moana is a popular beachside town for families to holiday at with their caravans and beach houses. The foreshore is dominated by towering Norfolk Island pines. With a beach pass, cars may be driven on the sand at Moana. 

Maslin Beach

Maslin Beach is Australia’s first nudist beach. One of the coast’s prettiest sites, ‘Maslin’s’ features a protected cove, high cliff-face and long expanse of sand. If you are keen to try out this popular bathing spot but wish to remain clothed, the northern end of the beach is the place to be.

Port Willunga

It was at Port Willunga in 1888 that the sailing ship ‘Star of Greece’ was driven ashore during a fierce storm, with the loss of 11 of its crew. At low tide the wreck is often partly exposed and is a popular site for snorkellers and scuba divers to explore.

Aldinga Beach

Aldinga Beach is very wide, with firm sand allowing vehicles with a beach pass to access certain sections. A launching area gives easy access to the water. Here divers can explore the Aldinga Aquatic Reserve with its spectacular ‘drop-off’ (an underwater cliff). Swimming and surfing are also popular here. If you walk along the boardwalk, you can see the Aldinga Scrub Conservation Park. 

Sellicks Beach

Sellicks Beach, the southernmost point of the City of Onkaparinga, is where the Mount Lofty Ranges meet the sea. Steep cliffs soon give way to a long expanse of sandy beach. This part of the coastline is renowned for its plentiful fishing and boat launching facilities. Cars with beach passes are also permitted on the beach below the Esplanade.
