The Airport Plan

The Airport Plan authorises the Stage 1 development of WSI (a single runway airport for up to 10 million passengers per year) and outlines the overall approach to its design and development.

Planning and environmental approvals have been achieved through the Environmental Impact Statement and the Airport Plan, both finalised in 2016.

We must follow a range of strict environmental conditions when we develop the airport. The project has to meet further approvals, including under the Environment Protection and Biodiversity Conservation Act 1999 for the flight path design. 

In July 2020, The Airport Plan was updated to authorise environmental mitigation and utility works to Badgerys Creek and Oaky Creek, in areas along the airport site. In September 2021, a further update was made to authorise the Sydney Metro – Western Sydney Airport Rail line to be built on the WSI site. We will deliver the airport in accordance with regulatory requirements.

The Department of Infrastructure, Transport, Cities and Regional Development is the regulator of the Western Sydney International Airport project and is also responsible for:

  • Flight path design
  • Forum On Western Sydney Airport (FOWSA)
  • Planning rail with New South Wales
  • Development approval
  • Biodiversity conservation through offsets
