Where the M5, M7 and Hume Highway meet, South-West Sydney's biggest transport, distribution and manufacturing belt runs through Ingleburn, Minto and Prestons — hundreds of warehouses, cold-storage sites, freight yards and factories along Williamson Road, Stennett Road, Airds Road, Rose Payten Drive, Blaxland Road, Kellicar Road and Bernera Road.
Industrial-spec machines handle the workshop / warehouse environment: reinforced glass, dust-resistant coils, high-capacity cold-drink columns. Product plans are tuned for shift workers — bigger snacks, energy drinks, cold water, protein bars, 600mL bottled water.
Just south, the Smeaton Grange / Gregory Hills / Campbelltown industrial fringe sits inside the same service zone, along with the Edmondson Park emerging employment area on the M7.
