Wellington is the small town in South Australia, Australia on the Murray River just upstream of where it empties into Lake Alexandrina. Its postcode is 5259. Wellington is in the Rural City of Murray Bridge. At the 2006 census, Wellington had a population of 295. Wellington was the original crossing of the Murray River for people, livestock, and goods travelling overland between Adelaide and Melbourne, until a bridge was built at Murray Bridge in 1879. There is still a ferry here. Some of the gold from the Victorian gold rushes crossed the Murray under police escort at Wellington.
