The Australian Government established WSA Co Limited (Western Sydney Airport, WSA or the Company) on 7 August 2017 to deliver and operate Western Sydney International (Nancy-Bird Walton) Airport (Western Sydney International or the Airport).

WSA is a wholly-government owned Commonwealth company, incorporated under the Corporations Act 2001, with Shareholder Ministers representing the Finance and Urban Infrastructure portfolios. WSA operates under the Public Governance, Performance and Accountability Act 2013 and at an arm’s length from the Australian Government. In doing so, WSA has considerable discretion in its operational and commercial decisions, within the constraints of the abovementioned legislation.

WSA’s mandate is to realise the Australian Government’s vision for Western Sydney International as set out in the Western Sydney Airport Plan (the Airport Plan) published in December 2016. The Airport Plan provides authorisation for the construction and operation of Stage 1 of the Airport. In doing so, WSA will deliver on the following objectives that are enshrined in its constitution:

• improving access to aviation services in Western Sydney by providing a broad range of passenger and freight services;
• resolving the long-term aviation capacity issue in the Sydney basin by maximising the aviation capacity of the site, noting the constraints at Sydney (Kingsford-Smith) Airport;
• maximising the value of Western Sydney International as a national asset including consideration of benefits the Airport will bring within and around Western Sydney, New South Wales (NSW) and Australia;
• optimising the benefit of Western Sydney International for employment and investment in Western Sydney by recognising that the Airport will be a major catalyst for growth and development in Western Sydney;
• effectively integrating with new and existing initiatives in the Western Sydney area by ensuring that long-term planning considers the Airport's economic, social and environmental impacts in Western Sydney; and
• operating on commercially-sound principles having regard to the Australian Government's intention to preserve its options with respect to ownership and governance arrangements by applying private sector discipline in the management of WSA.

Western Sydney International is a nationally significant infrastructure project that will generate economic activity both locally and nationally, provide employment opportunities, particularly for Western Sydney residents, and meet Sydney’s growing aviation needs. The Airport will expand to service a capacity of 82 million annual passengers (MAP) by the early 2060s and this will correspond to a level of economic and social activity that is transformative for the Western Sydney region and Australia.

WSA has premises located on-site including the WSA Site Office and the Western Sydney International Airport Experience Centre (the Experience Centre), and in the nearby metropolitan centre of Liverpool.
