Greystanes was originally an area of conflict between the Dharug people and the settlers. The name 'Greystanes', given by Nelson Lawson, came from the outcrops of basalt on Prospect Hill, "Grey" being its colour and "Stanes" being the Scottish word for stone. According to the 2016 census, the suburb has a population of approximately 22,500 people.
Greystanes is home to several churches, schools, parks, local shops and a wide range of public transport services. It is also in close proximity to the Cumberland Highway, the Great Western Highway and the M4 Motorway.
