Edmondson Park is located 39 kilometres from the Sydney central business district, in the local government area of the City of Liverpool.

[2][3] Edmondson Park lies on the Cumberland Plain, originally home to the Darug, Dharawal and Gundungurra Aboriginal language groups.

Large estates were broken up during the 1860s stem rust, which disrupted the grain industry, leading to the popularity of dairying, timber, fruit and wine production by locals instead.

[6] The South West Priority Growth Area was established by the NSW Government in 2005 to plan for urban expansion on Sydney’s fringes.

A number of smaller distributed commercial sites are located on Camden Valley Way in the north of the suburb, including the Village Square Shopping Centre.

Transit Systems operates scheduled buses that connect the suburb with other areas in the south west, including Narellan, Carnes Hill, Casula, Ingleburn and Liverpool.
