WSA Co was established in August 2017 to build the Western Sydney Airport, including construction of stage 1 and operation of the airport once open in 2026.
WSA Co is wholly owned by the Australian Government, represented by the Minister for Finance and the Minister for Urban Infrastructure as shareholder ministers.
The Australian Government will invest up to $5.3 billion for WSA Co to build Western Sydney Airport. This investment covers WSA Co's work on the earthworks and construction of the airport, including compliance with environmental conditions. It also includes funding for the Department of Infrastructure and Regional Development to develop and finalise the airspace and flight path design.
Western Sydney Airport is one of the largest civil engineering projects underway in Australia. Construction commenced in late 2018.
The Stage 1 airport will have a single 3.7-kilometre runway and facilities for up to 10 million annual passengers. The airport has been planned for staged development in the future. When needed, expected around 2050, a second parallel runway will be built.
