The Parkland was an area of specialty for the Darug people and it is still deemed as important by the Aboriginal Land Council.

[6] In November 2019, school students planted over 140,000 trees in the parkland to rejuvenate the critically endangered Cumberland Plain Woodland community that once predominated the Sydney region.

[7] The Parklands are formed by a series of connected green spaces, roughly following the western section of the M7 motorway and the M7 cycleway.

[8] The park is around 27 kilometres (17 mi) long, starting from the suburb of Quakers Hill in the north, to Leppington (Liverpool) in the south.

It features a conspicuous ridge that runs through it from north to south, providing panoramic views of Greater Western Sydney.

The parklands from Quakers Hill, Glendenning and all the way to Bungarribee are home to a large population of Eastern Grey Kangaroos.

Many breed in the Parklands' trees are found, such as rainbow lorikeets, rosellas, red-rumped parrots, galahs and cockatoos.

From north to south, the following parks, reserves, geographical features and sporting facilities are incorporated into the Western Sydney Parklands.
