Council Chamber in the Civic Centre at 10 Watson Terrace, Mount Gambier is the seat of local government for the City of Mount Gambier. The council was created in 1932 when the District Council of Mount Gambier West and District Council of Mount Gambier East merged to become the District Council of Mount Gambier which was later proclaimed a city on 9 December 1954. The city consists of a mayor and ten councillors, elected equally from the East and West wards once every four years by postal voting. The Mayor of Mount Gambier council is Lynette Martin. The local government area is situated entirely within the District Council of Grant and due to the city's growth there have been ongoing talks of amalgamation, the most recent boundary changes taking place in 2010.
