Shire of Cardinia: History
The areas within the present-day boundaries of Cardinia Shire were originally parts of the Cranbourne and Berwick districts, which were incorporated in 1860 and 1862 respectively. The Shire of Fern Tree Gully, later Shire of Sherbrooke, split away in 1889 and included areas to the east of Melbourne. In 1973, the City of Berwick, including Berwick and areas closer to Dandenong, split away from the Shire of Berwick, with the remainder being renamed Shire of Pakenham.
The Shire came into being on 15 December 1994 as the result of statewide local government reform, by merging the Shire of Pakenham with rural sections of the Shire of Sherbrooke and the City of Cranbourne.
The Shire of Cardinia contains the only area of Melbourne to use telephone numbers beginning with the exchange prefix 5 - this is a leftover from when it used the area code 059-xx xxxx.
