The completed Western Sydney International Airport features a state-of-the-art terminal and advanced operational technologies.
The Western Sydney International Airport has achieved a significant milestone by finishing its construction nearly seven months earlier than anticipated. As Australia’s first new international airport in over five decades, it represents a major enhancement in aviation infrastructure. Developed by Bechtel, the project was completed within a budget of AU$5.3 billion. With a terminal designed for 10 million passengers annually and various environmental innovations, the airport is poised to positively impact local employment and the economy, while also improving connectivity and competition in the aviation sector.
Australia’s first international greenfield airport in over 50 years, the Western Sydney International Airport (WSI), has been completed almost seven months ahead of its projected schedule. This landmark achievement occurred under the supervision of Bechtel, a major contractor based in Reston, Virginia, which managed the project since 2018.
The total budget for the WSI project was AU$5.3 billion (US$3.5 billion). Thanks to Bechtel’s effective oversight, including the coordination of various contractors for crucial components like earthworks, terminal construction, and the runway, the project has successfully met its objectives on time.
The new airport features a terminal that spans 82,000 square meters (882,640 square feet) and boasts a runway measuring 3.7 kilometers (2.3 miles) long. WSI is expected to accommodate up to 10 million passengers annually in its first year of operation, a significant boost to Australia’s transportation capabilities.
The construction phase of the airport resulted in 11,650 annual full-time jobs, with over half of these positions being filled by local residents. The project is expected to contribute AU$23.9 billion (US$15.4 billion) to Australia’s GDP by 2060, highlighting its significance to both the local economy and the nation as a whole.
Bechtel has placed a strong emphasis on sustainability throughout the project. Remarkably, 98% of water captured on-site has been reused, while 5.5 million tonnes of sandstone have been diverted from landfills during construction. The terminal’s design prioritizes energy efficiency by integrating natural light and implementing a roof capable of generating electricity.
WSI aims to become Australia’s largest international gateway by 2063. Future plans include provisions for a second runway and a fourth terminal, which will help accommodate the anticipated growth in air travel. Additionally, a dedicated metro line, currently under development by the New South Wales government, is being implemented to enhance transportation connections to the airport.
The airport will utilize cutting-edge technology, including a digital aerodrome management system, which facilitates remote monitoring of airport operations. This technological investment reflects a commitment to safety and efficiency for both passengers and airline operators.
WSI is set to provide a competitive alternative to Sydney’s Kingsford Smith Airport, which has stricter operational limits. Airlines such as Qantas and Singapore Airlines have already committed to offering services at the new airport, highlighting its readiness to serve the aviation market.
The official opening of the Western Sydney International Airport is scheduled for December 2026. Bechtel continues to work diligently to ensure the project meets its timelines while undergoing necessary testing and preparations for a smooth launch.
This ambitious project not only represents a major step forward for Australia’s infrastructure but also demonstrates the potential for job creation, economic growth, and environmental sustainability in large-scale construction endeavors.
