Western Sydney International Airport (under construction)

Not Applicable. The airport has not been closed. The site was acquired and cleared for the purpose of building a new international airport to serve Sydney's growing needs.

The site is an active, large-scale construction zone. As of 2024, major milestones have been achieved, including the completion of the runway and significant progress on the passenger terminal and other airside infrastructure. The project is being developed to be a 24/7, curfew-free airport capable of handling international, domestic, and cargo flights.

The airport itself has no operational history. However, the project has significant historical importance as the resolution to a decades-long search for a second Sydney airport site, a topic of debate since the 1940s. The land at Badgerys Creek was previously rural and farmland before being designated for this major national infrastructure project in 2014. The airport is officially named 'Western Sydney International (Nancy-Bird Walton) Airport' in honor of a pioneering Australian aviator.

The correct term is 'opening,' not 'reopening.' The airport is on schedule to commence operations in late 2026. It will operate with the official IATA code 'WSI' and ICAO code 'YSWG'. The identifier 'AU-0539' is not an official ICAO code and may be a temporary or non-standard placeholder from a third-party database.
