Coniston is a predominantly residential area; Mount Saint Thomas is thought to be named after the maiden name of the wife of Captain Charles Waldron.
Mount Saint Thomas is bounded by The Avenue, the WIN TV Station and Radio Station 200, Iris Avenue, the suburb of Mangerton, Gregory Street, McKenzie Avenue and Union Street in the north, Auburn Street, Miller Street and Tate Street in the east, Springhill Road and Gladstone Avenue in the south and the Southern Freeway in the west.
Significant development occurred during the post-war years, aided by immigration. The population has been relatively stable since the early 1990's, a result of some new dwellings being added, but a decline in the average number of persons living in each dwelling.
Major features of the area include WIN TV Station and Radio Station i98FM, Coniston Community Centre and one school.
