The Sydney Metro Western Sydney Airport project is set to deliver a vital boost to the Australian and NSW economies, providing an essential piece of road infrastructure to enable metro rail access to the airport site.  

The 23km driverless metro railway line consists of six metro stations between St Marys and Bringelly - two of which will be within the airport’s boundaries at the terminal and business park.

The Australian and NSW Governments are partnering to implement this project, which is expected to cost $11 billion. This significant rail investment will create jobs in Western Sydney while bringing new opportunities closer to home - supporting 14,000 jobs during construction.

Major construction of the Western Sydney Airport metro line is scheduled to start next year, allowing for the rail link to be operational ahead of the airport's opening in 2026.



Western Sydney Airport rail project overview

The Sydney Metro Western Sydney Airport project will service the future Western Sydney International (Nancy-Bird Walton) Airport and the Western Sydney Aerotropolis, interchanging with the T1 Western Line at St Marys.

The new railway link project will primarily connect residential areas with major employment centres, as well as provide connectivity from the new airport to the rest of the public transport system.

The project is expected to deliver a fast, safe, and reliable metro, as well as support the future Western Parkland City - covering council areas of Liverpool, Campbelltown, Penrith, Hawkesbury, Camden, Wollondilly, Fairfield, and Blue Mountains.

Other key features of the rail project include:

  • the ability to transport 7,740 commuters an hour in each direction, taking around 110,000 vehicles off local roads every day
  • six new metro stations: St Marys (connected to the existing railway station), Orchard Hills, Luddenham Road, Airport Business Park, Airport Terminal, and Aerotropolis
  • two stations on the airport site, including a station at the airport’s integrated international and domestic terminal, as well as the on-airport business park.  These two stations will provide efficient access for aviation passengers as well as service jobs and businesses that will call the airport home in the future
  • modifications to St Marys railway station to support the transport interchange at Orchard Hills
  • infrastructure works such as transport interchanges, car parks, and public domain works to support station precincts.

Delivering local jobs for Western Sydney

Rail infrastructure projects such as the Western Sydney Airport project will be the driving force behind the NSW economy, providing essential employment for the local community.   

The major investment has been described as a city shaping infrastructure. It is likely to generate 14,000 jobs, including 250 apprenticeships.  This includes tradespeople, tunnellers, and truck drivers.   

The new metro link is also crucial for achieving the 200,000 local jobs objective of the Western Sydney City Deal.  Minister for Population, Cities and Urban Infrastructure, Alan Tudge said the City Deal will continue to deliver for the people of Western Sydney for generations to come.  

Mr Tudge concluded, “The Western Sydney Aerotropolis and Western Sydney International (Nancy-Bird Walton) Airport will attract infrastructure, investment, and skilled jobs, and the benefits will flow into health and education, retail, hospitality and industrial activities that will power the region.”

The collaboration from the three tiers of government (federal, state and local) has provided favourable city-building initiatives to improve the prosperity, sustainability, and liveability of Western Sydney.



It’s full steam ahead in the rail infrastructure space, especially when it comes to the city shaping Sydney Metro Western Sydney Airport project.  


Set to become the transport backbone for the growing region, it will connect communities with the new airport - while generating much needed employment opportunities.  It will also deliver community initiatives with a focus on health, education and leisure facilities across Greater Sydney.
