Casey City was formed in 1994 by the union of most of Berwick City, the western half of Cranbourne Shire and part of Sherbrooke Shire. Its area is 395 square km and it is headquartered at the former Berwick City offices at Fountain Gate, Narre Warren. It is named after Baron Casey of Berwick, Victoria and the City of Westminster (1890-1976) politician and Australian governor-general. Casey lived at Edrington, Berwick, from the 1940s until his death.
Casey City's boundaries are:
West: Dandenong Creek from Endeavour Hills to Doveton, then South Gippsland Freeway and Western Port Highway to Western Port Bay.
North: Irregular line through Lysterfield Ranges and Narre Warren North to Cardinia Creek.
East: Cardinia Creek and Tooradin Station Road to Western Port Bay.
South: Western Port Bay from Watson Inlet to east of Tooradin.
The territory encompasses the foothills of the Dandenong Ranges, lower undulating to flat country (Berwick, Cranbourne) and lower land with extensive drains for agriculture.
Population is concentrated along the Princes Highway, Monash/Princes Freeway and Gippsland rail corridor, together with the South Gippsland Highway and Cranbourne rail corridor. During the 1990s-2000s the space between Berwick and Cranbourne was urbanised (Cranbourne North and Narre Warren South). The rail service beyond Cranbourne ceased in 1993 but that did not stop the development of Cranbourne East: a railway station there may come. Much of the non-urban land such as at Clyde, Harkaway and Pearcedale is rural/residential. On Western Port Bay there are small towns such as Warneet and Tooradin.
The precise ways in which rural has given way to urban can be found by checking the place names listed at the end of the entries for Berwick Shire/City and Cranbourne Shire.
