Western Sydney’s first direct public transport links to the new international airport will begin on Sunday 5 July, two weeks after separate 24/7 bus services started between Parramatta, the CBD and Liverpool.
Six new electric bus routes will run seven days a week from 5am to 10pm, every 30 minutes, connecting Penrith, Mount Druitt, Liverpool, Campbelltown, Oran Park and Leppington to the Western Sydney International Airport precinct. Until a rail line is completed, these buses are the only scheduled public transport option for airport workers, early travellers and residents in some of Sydney’s fastest-growing suburbs.
Transport for NSW confirmed the timetable and route details on 21 June, the same day Route 52 (Parramatta to the CBD via Ryde) and Route 80 (Parramatta to Liverpool via the T-way) began running around the clock. Those services are already carrying passengers. The five new airport-focused routes and one redesigned local link join them in a fortnight.
The new routes are 772 (Mount Druitt to WSI Airport via St Clair and the Great Western Highway, about 60 minutes), 790 (Penrith to WSI Airport via Kingswood, also connecting Penrith CBD to Nepean Hospital in about 10 minutes), 825 (Liverpool to WSI Airport via Bonnyrigg), 840 (Campbelltown Hospital to Leppington via Oran Park, replacing route 858), 845 (Campbelltown to WSI Airport via Oran Park, about 66 minutes), and 860 (Liverpool to WSI Airport via Leppington). All services use the new bus interchange at the airport site.
The rollout includes 22 Volvo BZL Electric buses delivered after depot upgrades at Penrith. Riders will notice a quieter cabin and faster, smoother acceleration compared with older diesel vehicles. Transport for NSW said the electric fleet supports the state’s net-zero 2050 target, and the agency partnered with community organisation Big Yellow Umbrella to consult residents on final route designs.
For people in the new estates around Oran Park and Leppington, the changes are the first frequent, all-day public transport to a major employment hub. Until now, reaching the airport area meant a car trip or an indirect combination of existing bus and train services. The 30-minute headway means workers on early or late shifts won’t be stranded, and the 5am start is timed for the airport’s first ground crews.
The new network does not replace every diesel bus on these corridors overnight, but it establishes a spine of zero-tailpipe-emission public transport in a region where passenger numbers are rising fast. If you are travelling from Penrith or Liverpool to the airport for the first time, forward-facing window seats offer a clear view of the aerotropolis taking shape along Elizabeth Drive.
Passengers should check their route number before boarding. The main airport services start on 5 July, not when the Parramatta routes began. The WSI Airport bus interchange is the central connection point for all five new airport routes, and the 840 provides the link from Campbelltown Hospital through Oran Park without requiring a car.
The airport itself opens in October 2026. Between now and then, the electric buses will carry construction workers, logistics staff and security teams. When the first passenger flight pushes back, the quietest ride to the terminal will have been running for three months.
