Barker Inlet, Tidal inlet in Adelaide, South Australia.

Barker Inlet is a tidal waterway stretching between St Kilda and Port Adelaide along the Gulf St Vincent coast. It is characterized by mangrove forests, seagrass beds, and broad mudflats.

The inlet is named after Captain Collet Barker, who first sighted it in 1831. From 1906 until 1972, its Broad Creek served as a landing point for explosives, carried by a 2.4 km tramway to the Dry Creek explosives depot. Abandoned iron and wooden ships were left in Broad Creek, Angas Inlet and the North Arm up to 1945.

The inlet lies within the traditional country of the Kaurna people, who harvested its shellfish and fish and gathered materials for shelters and tools. The inlet's name honours Captain Collet Barker, who sighted it in 1831. Today the waterway is a reserve for dolphins, fish, crabs and aquatic plants, and its mangrove creeks and samphire flats are visited for birdwatching and canoeing among the abandoned hulls.

The inlet is accessible via boardwalks at Garden Island and St Kilda, where you can observe marine creatures and coastal plants up close. Visiting during high tide provides easier access to the water edges.

More than 30 sunken ships from before 1945 rest on the bottom and serve as natural perches for bird species. These submerged wrecks create habitats that seabirds and other animals depend on.
