Three consortia have been shortlisted to deliver the tunneling works of the new Metro railway line, which will service Greater Western Sydney and the new Western Sydney International (Nancy-Bird Walton) Airport.

The shortlisted consortia are:

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

The successful tunnel builder will deliver 10km of twin Metro railway tunnels and the associated excavations of station boxes.

The station box and tunnelling contract is expected to be awarded by the end of 2021, with the first of four mega tunnel boring machines expected to be in the ground by the middle of 2023.

The Federal and NSW governments are jointly delivering the 23km 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.
