Western Sydney Airport line is a proposed 23km-long railway line connecting the new Western Sydney International (Nancy-Bird Walton) Airport to Sydney’s rail network.

The new railway link project will primarily connect residential areas with major employment centres, including the new Western Sydney Aerotropolis project. It will also 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, which covers the council areas of Liverpool, Campbelltown, Penrith, Hawkesbury, Camden, Wollondilly, Fairfield and Blue Mountains in Australia.

Construction of the new railway line will commence by the end of 2020, with completion expected in time for the opening of the Western Sydney Airport in 2026.

The railway link is expected to create 14,000 jobs during the construction phase, including 250 new apprenticeships and will also contribute to the local economy.

Western Sydney Airport line development

The Sydney Metro – Western Sydney Airport project was formerly known as Sydney Metro Greater West and North South Rail Link.

The project forms a major part of the Western Sydney City Deal, which is a 20-year agreement signed by the Australian and New South Wales (NSW) governments, and eight Western Sydney councils in March 2018. The development of the first stage of the Sydney Metro – Western Sydney Airport line is part of the deal.

An online survey was conducted in July 2020 to gather insights from the community on the usage of the new metro service.

The environmental impact statement will be released for public feedback before the start of construction.

Western Sydney Airport line details

The railway line will serve the Western Parkland City, which includes the new Western Sydney International Airport and Badgerys Creek Aerotropolis.

The line will also have the provision of northward extension to Schofields to connect to the Richmond railway line, and southward to the Main Southern railway line near Macarthur.

The railway line will run through a tunnel from St Marys to the south of the M4 Motorway and from Oran Park to the Main South Line near Macarthur.

Western Sydney Airport Line stations

The proposed railway line will have six new metro stations, including St Marys, Orchard Hills, Luddenham, Western Sydney International Business Park, Western Sydney International Airport Terminal, and Western Sydney Aerotropolis.

St Marys station will be an important part of the project as it will serve as an underground interchange station, which will connect passengers to other parts of Sydney through the existing Sydney Trains rail network.

Orchard Hills station will service a future mixed-use urban village while the station at Luddenham will offer transport links for future education, innovation and commercial areas.

The airport site will have two stations, which includes one at the airport’s integrated international and domestic terminal and the other at the airport business park.


The Sydney Metro – Western Sydney Airport line is being funded jointly by the federal and state governments on an equal basis under the Western Sydney City Deal.

The construction of the project will require a total investment of approximately A$11bn ($7.42bn).  In April 2019, the federal government announced a contribution of A$3.5bn ($2.5bn) for stage one delivery in the 2019-2020 budget. The funding includes A$50m ($35.85m) for the business case process of the project and A$61m ($43.74m) for the Elizabeth Drive overpass.

The Australian and NSW Governments approved another A$3.5bn ($2.36bn) in funding to support the construction of the project in June 2020.

Contractors involved

Aurecon is assisting Transport for NSW in the identification of rail corridors for the metro rail project. It provided a draft strategic environmental assessment of the impacts and benefits of developing future public transport infrastructure at the proposed project site.
