With construction of the new airport almost complete, the Australian Government will see the country’s most significant aviation project in over 50 years enter the final testing and operational readiness phase later this year. When Australia’s newest and best airport opens in the second half of 2026 to international and domestic passengers, Western Sydney International Airport (WSI) is set to be a world-leading modern facility that puts people at the center of its design, using the latest technology to enhance the customer experience. Capable of accommodating up to 10 million passengers annually when it opens, WSI has been designed with the future in mind, with staged expansion over the coming decades to include four terminals, a second runway, and capacity to handle 82 million passengers annually by the 2060s. 

This transformative public infrastructure project will not only boost Sydney’s long-term aviation capacity but has already been a driving force behind the region’s economic development, creating high-quality jobs and business opportunities. Since 2018, when construction started on the AU$5.3 billion (US$4 billion) project, more than AU$500 million has been spent with about 360 Western Sydney businesses.
