South Western Sydney is a region of the city of Sydney, New South Wales, Australia. It is situated in the south-west of the larger Sydney metropolitan area, and is part of the predominantly working class area of Greater Western Sydney. In the early 2010s, urban development has occurred in places like Camden and Campbelltown. Areas such as Leppington, spanning Liverpool, Camden and Campbelltown councils, had higher number of families. In 2004, Leppington was identified as part of Sydney's South West Growth Centre. Edmondson Park, being part of the South West Growth Centre, is also expected to see significant growth and development over the next 10 years.
There are a number of different boundaries and definitions for Sydney's South-West with majority of definitions including the suburbs within City of Liverpool as well as surrounding areas. This can also include the Macarthur region which is often referred to as 'Outer South-West', particularly referring to the local government area of City of Campbelltown as well as Camden Council and occasionally also the Wollondilly Shire. City of Canterbury-Bankstown is also often included in definitions of Sydney's South-West and usually referenced as being 'Inner South-West'. In the broadest sense, South-Western Sydney can also include Fairfield City Council as it is south of Prospect Reservoir even though geographically the council is west of Sydney CBD and not south-west.
