Eastern Creek is located 35 kilometres west of the Sydney central business district, in the local government area of the City of Blacktown and is part of the Greater Western Sydney region. Eastern Creek is west of the Prospect Reservoir and is most notable for containing the Eastern Creek Raceway and the former site of Wonderland Sydney amusement park. It is quite close to the suburbs of Arndell Park, Doonside & Rooty Hill. Eastern Creek features many industrial developments and often the description 'Eastern Creek Area' also includes the industrial developments in the neighbouring suburbs of Arndell Park and Huntingwood. By road Eastern Creek is adjacent to the Westlink M7 motorway which can provide very easy access to the Great Western Highway and the M4 Motorway, providing road access to the western sections of the city and eastward to the Sydney CBD.
