Prospect, New South Wales in the context of "Greater Western Sydney"

Prospect Hill is a heritage-listed hill in Pemulwuy and Prospect in the greater western region of Sydney, New South Wales, Australia. Situated about 30 kilometres (19 miles) west of central Sydney, the hill is Sydney's largest body of igneous rock and is higher than the ridges of the Cumberland Plain around it, with its present-day highest point being 117 metres (384 feet) high, although before its summit was quarried away it rose to a height of 131 metres (430 feet) above sea level.

Prospect Hill is a free-standing hillock which is disconnected from Marrong Reserve to the south at a saddle by Butu Wargun Drive. Prospect Hill is a “nodal point” of the Cumberland Plain. Its summit affords a “goodly prospect” west to the Blue Mountains and east to the man-made landmarks of central Sydney. People have walked round and over Prospect Hill for 30,000 years and have recognised it as a landmark, a meeting place and a boundary. For today's Australians it has historic significance, aesthetic values and commercial values. Owned by Boral Limited and CSIRO, the site was added to the New South Wales State Heritage Register on 17 October 2003.

Pemulwuy is a suburb in Greater Western Sydney, in the state of New South Wales, Australia. Pemulwuy is located 30 kilometres west of the Sydney central business district in the local government area of the Cumberland Council. Pemulwuy is home to the highest point between the Blue Mountains and Sydney, the summit of Prospect Hill.

The quarrying of blue metal, basalt and dolerite was abundant in the area in the past two centuries. Pemulwuy, formerly part of Prospect, is a relatively new suburb, with development beginning in 2004 on the site of a former Boral quarry and CSIRO sites.
