Sydney’s long-awaited Western Sydney International (Nancy-Bird Walton) Airport (WSI) has reached a major milestone with the completion of its state-of-the-art terminal, formally unveiled today.
The project, located in Badgerys Creek, is the first new greenfield international airport built in Australia in over 50 years and is set to open its doors to passengers in late 2026.
The unveiling event brought together Prime Minister Anthony Albanese, Minister for Infrastructure Catherine King, WSI CEO Simon Hickey, and senior executives from key partners including Qantas Group, Singapore Airlines, Menzies Aviation, and dnata Catering & Retail.
The completion of major construction works signals a transformative moment for Greater Sydney, promising to reshape the region’s economic and cultural landscape.
From its inception, the WSI terminal has been designed to reflect the natural beauty and cultural heritage of Western Sydney.
The initial design concepts were developed by global architecture leaders Zaha Hadid Architects and Australia’s COX Architecture, following a fiercely competitive international design competition in 2019.
The design and construction were delivered by Multiplex and Woods Bagot, with overall project management by Bechtel.
Simon Hickey, CEO of Western Sydney International Airport, emphasised the significance of the project for the region: “We are on the precipice of launching a seamless and stress-free airport experience unlike any other in Australia.
“WSI will give our global city a 24-hour international gateway that will continue to create significant economic opportunities for all of Greater Sydney.”
The terminal’s architecture draws inspiration from the World Heritage-listed Greater Blue Mountains and the Cumberland Plain, with a feature ceiling that echoes the iconic vistas of the surrounding landscape.
Extensive use of locally sourced sandstone and references to Dharug country ensure that the terminal is not just a transit hub, but a celebration of more than 60,000 years of Aboriginal culture.
The terminal sets a new benchmark for airport design in Australia, combining sustainable principles with cutting-edge technology.
A climate-responsive façade and over 6,000 solar panels help reduce the airport’s carbon footprint, while rainfall collection and recycling systems support operations such as bathrooms, irrigation, and cooling towers.
Cristiano Ceccato, Director and Design Lead at Zaha Hadid Architects, highlighted the global significance of the project: “This is a rare opportunity to define the next generation of airport design on a global stage.
“Together with COX, we created a design that meets the highest standards of architectural innovation, passenger experience and operational efficiency.
“What makes this terminal extraordinary is its blend of human-scaled design and international ambition.
“It is grounded in its setting — and yet globally competitive.”
Passengers can expect a streamlined departure experience, with both domestic and international gates housed under one roof for simple and efficient connections.
Advanced technology will enable travelers to move through the airport quickly, while the intuitive layout and open sightlines create a welcoming and egalitarian atmosphere.
The construction of WSI has already delivered significant economic benefits to the region, with more than $500 million spent with Western Sydney businesses and nearly half the workforce drawn from the local community.
The airport is expected to drive billions in further investment and create thousands of jobs across the precinct and the emerging Bradfield City and Aerotropolis.
David Holm, Principal and Design Lead at COX Architecture, reflected on the project’s impact: “At COX, we’ve always believed in the power of public architecture to shape cities across generations.
“Few projects align so closely with that mission as this — a new airport, for a new generation.”
As the fit-out of retail precincts and airline lounges continues ahead of the official opening, the completion of the WSI terminal stands as a testament to collaboration, innovation, and the enduring spirit of Western Sydney.
The airport is poised to become a world-class gateway, connecting Australia to the globe and ushering in a new era for the nation’s aviation sector.
