The borders of the City of Frankston were redrawn in 1994, excising its southern suburbs of Baxter and Mount Eliza to the new Shire of Mornington Peninsula, and gaining the north-eastern suburbs of Carrum Downs and Skye from the City of Casey and the former City of Springvale. The proposed name of the new city was initially "City of Nepean", but the historic name of Frankston (which had been used for its local government areas for over 100 years) was ultimately kept.
