Transport for NSW has announced a shortlist of three consortia to build the new metro railway line to Western Sydney Airport.

The shortlisted groups are:

  • Bouygues Construction Australia Pty Ltd
  • John Holland Gamuda Joint Venture
  • Acciona Construction Australia Pty Ltd


Construction will include creating 10 kilometres of twin metro railway tunnels and the associated excavation of stations along the route.

A contract for the station box and tunnelling construction is expected to be awarded before the end of 2021.

The first of four tunnel boring machines to be deployed on the project is scheduled to be in the ground by the middle of 2023.

The Federal and NSW governments are jointly delivering the 23 kilometre Metro railway and six stations between St Marys and the Western Sydney Aerotropolis, including two stations at the airport.

The project will support 14,000 jobs, including 250 apprentices.
