Port Adelaide is a suburb of Adelaide, the state capital of South Australia, approximately 14km northwest of the Adelaide CBD. It lies within the City of Port Adelaide Enfield and is the main port for the city of Adelaide. Port Adelaide played an important role in the formative decades of Adelaide and South Australia, with the port being early Adelaide's main supply and information link to the rest of the world.HistoryPrior to European settlement Port Adelaide was covered with mangrove swamps and tidal mud flats, and lay next to a narrow creek. The entrance to this creek, the Port River, was first reported in 1831. It was explored by Europeans when Captain Henry Jones entered in 1834. The creek's main channel was then fed by numerous smaller creeks, and was 2- deep. The navigable channel was narrow and the creek soon faded into swamps and sandhills. At low tide the channel was surrounded by mudbanks. Dry and solid land ended near present-day Alberton.Colonel William Light began closely exploring the area in late 1836 while deciding on a site for the colony of South Australia's port. After initial trepidation, he reported to the Colonisation Commissioners that the location was a suitable harbour. By this time it had acquired the name "the port creek". Light's choice of separating the port and Adelaide was strongly opposed by a few merchants, a newspaper and Governor John Hindmarsh. This opposition was largely based on the distance between them. The division of power in the colony meant that the final decision was Light's alone. He kept Adelaide and the port separate principally due to the lack of fresh water at the port.
