The Western Sydney Airport - Station Boxes and Tunnelling Works Project forms part of the broader Sydney Metro network. The project involves the construction and operation of a new 23km metro rail line from the existing Sydney Trains suburban T1 Western Line (at St Marys) in the north and the Aerotropolis (at Bringelly) in the south. The alignment includes tunnels and civil structures, including a viaduct, bridges, and surface and open-cut troughs between the two tunnel sections.

The Project will be delivered through several works packages including the Station Boxes and Tunnelling Works (SBT Works), which includes the design and construction of:

• Two sections of twin tunnels with a combined length of approximately 9.8km, plus associated portal structures, one from Orchard Hills to St Marys and the other under Western Sydney International (WSI) airport to the new Aerotropolis Station
• Excavations at either end to enable trains to turn back, and stub tunnels to enable future extensions
• Station box excavations with temporary ground support for four stations at St Marys, Orchard Hills, Airport Terminal and Aerotropolis
• Excavations for two intermediate services facilities, one in each of the tunnel sections at Claremont and Bringelly.
