Sydney Metro—Western Sydney Airport

The Australian Government is contributing up to $5.25 billion to deliver Sydney Metro - Western Sydney Airport (formerly the Western Sydney North South Rail Link).

A key commitment of the Western Sydney City Deal, the Australian Government and NSW governments are partnering to jointly fund and deliver rail to Western Sydney International (Nancy-Bird Walton) Airport for its opening in 2026. The total project cost will be around $11 billion.

The Australian Government contribution includes:

  • $60 million towards the Western Sydney North South Rail Link (Sydney Metro - Western Sydney Airport) joint business case process.
  • $5.19 billion towards the delivery of Sydney Metro - Western Sydney Airport. This is inclusive of the $61 million to construct the Elizabeth Drive Overpass, an essential piece of road infrastructure to enable metro rail access to the airport site.

In the 2022-23 Budget, the Australian Government committed $77.5 million towards the development of a Final Business Case for the extension of Sydney Metro – Western Sydney Airport from Bradfield to Glenfield via Leppington. The Final Business Case will provide the economic assessment, design and cost estimation to inform an investment decision for the construction of the extension.
