The Western Sydney Airport – Airport Plan (Airport Plan) outlines the approach to the design and development of Western Sydney International (Nancy-Bird Walton) Airport (WSI).

The Airport Plan was originally prepared in 2016 to provide the authorisation for the initial stage of WSI (a single runway facility capable of handling up to 10 million passengers per year).

Delivering road and rail networks

The Australian and NSW Government's road and rail infrastructure investment in support of the Western Sydney International (Nancy-Bird Walton) Airport (WSI) will provide the connections needed for day one airport operations.

The more than $2 billion M12 Motorway project, which was completed in March 2026, delivered a toll free 16km east-west motorway between the M7 Motorway near Cecil Hills and The Northern Road at Luddenham. The M12 Motorway will serve as a major access route to WSI and connect to Sydney’s broader motorway network.

The importance of land and history

Respecting the natural environment and cultural heritage is an important part of the Western Sydney International (Nancy‑Bird Walton) Airport (WSI) project.

Planning and construction have carefully considered the environment and heritage at the site and nearby areas, and established measures to minimise impacts.

Aboriginal cultural heritage

The government will continue to work closely with the Aboriginal community to protect and preserve Aboriginal cultural heritage in its delivery of WSI.
