The late 19th century saw substantial residential and commercial development such that by 1891 Prahran had a population of almost 40,000 and Malvern 11,000. Following the election of the Kennett government in the Spring of 1992, as part of a comprehensive reorganisation of local government in Victoria, the Cities of Malvern and Prahran were amalgamated to form the City of Stonnington.
