St Kilda, South Australia

St Kilda is a coastal hamlet, now classed as a suburb, 21 kilometres (13 miles) north-north-west of the centre of Adelaide, capital city of South Australia. With a population below 100 and a sole 4-kilometre (2.5-mile) road connecting to the nearest highway, its natural and built resources have remained relatively undisturbed. The seafront, containing a large area of mangroves, faces the Barker Inlet, which is part of the Port River estuarine area. St Kilda is an internationally recognised bird-watching area: more than 100 species of birds feed in and around the mudflats, salt lagoons, mangroves and seagrass beds.

The inhabited section of the suburb occupies less than 100 hectares (250 acres) along the seafront. The remainder of the land was formerly used for extensive salt evaporation ponds, although now they are much fewer in number. The settlement ponds of the Bolivar Waste Water Treatment Plant occupy some of the southern end of the suburb. St Kilda is bordered by Buckland Park to the north, Waterloo Corner to the east-north-east, Bolivar to the south and south-east, and Gulf St Vincent to the west.

The suburb is home to a number of tourist attractions, including an adventure playground, tram museum, mangrove forest walk and an abundance of birdlife.
