Pemulwuy is located 30 kilometres west of the Sydney central business district in the local government area of the Cumberland Council.

[5] In 1791 Governor Arthur Phillip started granting plots of land (mostly 12 to 28 hectares (30 to 70 acres)) to emancipated convicts in what is now Pemulwuy.

[8] On 1 May 1801 Governor King took drastic action, issuing a public order requiring that Aboriginal people around Parramatta, Prospect Hill and Georges River should be "driven back from the settlers" habitations by firing at them'.

In 1808 William Lawson was granted 220 hectares (550 acres) on the western slopes of the west ridge where he was to build his home Veteran Hall.

He then bought Cummings' grant and it was here that his third son, Nelson Lawson built a magnificent home, Grey Stanes, on the crown of Prospect Hill.

[13] By the latter part of the nineteenth century coarse-grained picrite, and other doloritic rock types were being extracted from William Lawson's estate on the west and north sides of the Hill.

Prospect Hill was for many years the primary source of road stone for the city's expanding infrastructure until the reserves of dolerite were exhausted.

This site will eventually be integrated with the Nelson's Ridge development through Driftway Drive as well as cycleways and pedestrian links being established between the two.

[19] Philip Gidley King mentions that the landscape of Prospect is "a very pleasant tract of country, which, from the distance the trees grew from each other, and the gentle hills and dales, and rising slopes covered with grass, appeared like a vast park.

[20] Prospect Hill, which lies in the suburb, is Sydney's largest body of igneous rock and rises to a height of 117 metres above sea level.

The Early Jurassic activity resulted in the shaping of the Prospect dolerite intrusion, which unequivocally points that the hill had a volcanic origin.

[21][22] The eroded residue of the volcanic core forms Prospect Hill, which was battered down over millions of years to a small bulge, which is a laccolith, in the generally flat lands of western Sydney.
