The name was spelt as two words into the late 1800s,[4] but the name continues in use today as the single word "Crossroads", being a locality within Casula, New South Wales and adjacent to modern Prestons, around the intersection of the Hume Highway/Campbelltown Road, and Camden Valley Way (formerly called Bringelly Road).

Prestons is situated at an important road junction (Sir Roden Cutler VC Memorial Interchange) where the M5 South Western Motorway from the city meets the Hume Motorway heading towards Canberra and Melbourne and the Westlink M7 heading towards Mount Druitt and northern Sydney.

Prestons is serviced by trains to the city via Granville and the Airport from Glenfield and Edmondson Park stations.

Prestons Robins Little Athletics operates every Wednesday and Friday nights at the new park on Ash Road during summer months.
