Western Sydney Airport Bus Routes Announced With Services Starting July 2026

Western Sydney commuters are about to get a major transport boost.

Five new permanent bus routes connecting key Western Sydney communities to Western Sydney International Airport will begin running from 5 July 2026, three months ahead of passenger flights launching at the airport.

The new services—spanning Penrith, Campbelltown, Liverpool and Mount Druitt—are part of a $302.7 million investment in Western Sydney bus services, aimed at improving transport access across one of Sydney’s fastest-growing regions.

Here’s what to know about the new routes and how they’ll work.

Which New Bus Routes Are Being Added

Five new permanent routes will connect surrounding suburbs to Western Sydney International Airport.

The new routes include:

• Route 790 — Penrith to Western Sydney International Airport
• Route 845 — Campbelltown to Western Sydney International Airport
• Route 825 — Liverpool to Western Sydney International Airport
• Route 860 — Liverpool to Western Sydney International Airport
• Route 772 — Mount Druitt to Western Sydney International Airport

The routes are designed to connect local communities with the growing number of jobs and businesses emerging around the airport precinct, particularly in construction, freight and logistics.

Premier Chris Minns said the services are a critical part of preparing Western Sydney for its next phase of growth.

When The Western Sydney Airport Bus Services Start

The five routes will officially begin running on 5 July 2026, ahead of the airport’s passenger flights scheduled to begin later in the year.

Buses will operate every 30 minutes from 5am to 10pm, seven days a week, making them one of the most frequent services currently operating across the region.

The new routes will also run alongside WSI Link, an interim shuttle service that will connect the airport to St Marys Station until the Sydney Metro–Western Sydney Airport line opens in 2027.

What The New Electric Buses Will Be Like

The services will be operated using 43 new electric buses, designed to offer a quieter and smoother ride while supporting the NSW Government’s goal of net zero emissions by 2050.

The buses feature:

• Full air conditioning
• Low-floor kerb access for improved accessibility
• Luggage racks for airport travellers

Fit-out and finishing work for the new fleet took place locally at the Volgren facility in Ingleburn and the Foton facility in Nowra, helping support regional manufacturing jobs.

To support the rollout, bus depots in Western Sydney have also been upgraded.

The Busways Penrith depot has already reached 50% charging capacity, while the Transit Systems depot in Bradbury has been electrified to support the remaining buses.

What It Means For Western Sydney

The new routes form part of a broader $362.7 million investment in Western Sydney bus services announced since the Minns Government took office.

Transport Minister John Graham said the new routes address long-standing gaps in public transport across the region.

Alongside the new routes, the NSW Government will also trial a $1.5 million Bus Shelter Program, allowing local councils to apply for funding to install shelters along new or improved routes—something many Western Sydney suburbs currently lack despite experiencing some of Sydney’s hottest temperatures.

Road upgrades along Badgerys Creek Road are also underway to improve access to the new airport before the services begin operating.
