Prospect is a suburb of Sydney, in the state of New South Wales, Australia. Prospect is located 32 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.
The suburb of Prospect takes its name from the prominent nearby landmark of Prospect Hill - from the top of which people could get a prospect of (see a great distance) the surrounding countryside. Initially a settlement for emancipated convicts, it later became a village.
Since colonisation, settlers cleared larger areas of land to raise livestock, build churches, inns, schools, shops and a large reservoir. The quarrying of blue metal was abundant in the area. Naturalist Charles Darwin visited Prospect in January 1836, to observe the geology.
