There were great celebrations at the opening of Sydney’s new airport; now it’s time to deliver on its promises for jobs, transport, and environmental protection.
The opening of Western Sydney International (Nancy-Bird Walton) Airport marks a historic milestone for Western Sydney and Australia. Its first domestic passenger flight departed on Sunday 25 October, followed by the first international service on Monday.
After some eight decades of debate, Australia’s first major new airport in more than half a century deserves celebration. This is a once-in-a-generation investment with the potential to reshape Western Sydney’s economic geography, open new international connections and create opportunities across one of Australia’s fastest-growing regions.
The journey has been long. The search for Sydney’s second airport dates back to the 1940s. The Hawke government selected Badgerys Creek in 1986, the Abbott government confirmed the site in 2014, and construction began in 2018. Its completion reflects successive governments’ commitment to expanding Sydney’s aviation capacity.
There is much to welcome: new investment, international connectivity and employment opportunities. But opening day also marks a transition from forecasts and aspirations to demonstrating results. The debates about jobs, transport and environmental protection are longstanding. What matters now is how these ambitions are delivered together.
Turning employment ambitions into local opportunities
More than 13,000 people helped deliver the airport precinct, over half from Western Sydney. Looking ahead, the airport operator projects up to 8500 jobs supporting operations as passenger numbers grow towards 10 million annually in the 2030s.
The ambitions extend further. The 2018 Western Sydney City Deal envisaged 200,000 new jobs across Western Parkland City over 20 years. How realistic does that ambition remain, and what progress has been made?
Bradfield City Centre and the Aerotropolis are intended to attract advanced manufacturing, technology, logistics and research-intensive industries. As Western Sydney University Chancellor and Bradfield Development Authority Chair Jennifer Westacott has argued, the opportunity is to create “more and higher value jobs”.
These ambitions are significant, but their success cannot be judged by projections alone. The real opportunity is to connect new industries with Western Sydney’s diverse workforce, creating pathways into skilled, rewarding employment and helping address the longstanding imbalance between where people live and where jobs are located.
Encouragingly, Western Sydney University is already contributing through aviation training and advanced manufacturing partnerships, alongside government and industry partners.
The wider lesson for Australia is that major infrastructure investment does not automatically translate into inclusive economic growth. Realising its benefits requires connecting new industries and employment opportunities with the skills and aspirations of surrounding communities.
Transport connections: from planning to delivery
The airport has opened before completion of its planned Sydney Metro connection. Significant investments, including the toll-free M12 motorway, road upgrades and interim airport buses, have improved access, but the missing rail link remains significant.
Western Sydney does not suffer from a shortage of transport strategies, expert panels or infrastructure promises. A Commonwealth-appointed independent panel in 2023 identified 36 transport priorities. The real challenge is translating these into coordinated, funded and timely delivery.
The Metro delay reflects construction and contractual difficulties, rather than simply a lack of funding. Contractor disputes and potential cost overruns have complicated delivery, with completion potentially slipping to 2028.
For a region already experiencing car dependence, congested roads and lengthy commutes, the stakes extend beyond airport passengers. Workers, visitors, freight operators and growing Aerotropolis businesses all need reliable and affordable connections.
The wider lesson for Australia is clear: the economic and social value of major infrastructure depends on delivering the connecting networks alongside it, ensuring accessibility keeps pace with growth.
The responsibilities of a 24-hour airport
Unlike Sydney’s Kingsford Smith Airport, Western Sydney International operates without a curfew.
Round-the-clock operations offer significant economic advantages for international aviation and freight, but also bring responsibilities for managing night-time noise and environmental impacts. Initial flight movements may be modest, but their long-term consequences cannot be judged by the first few weeks.
The Greater Blue Mountains World Heritage Area warrants particular care, given its internationally significant biodiversity and natural values. In 2025, UNESCO’s World Heritage Committee requested that Australia assess potential airport impacts on the area’s Outstanding Universal Value, avoid negative impacts and report on its conservation by December 2027.
The Commonwealth has established environmental monitoring requirements, including monitoring within and adjacent to the Greater Blue Mountains.
There are practical lessons from elsewhere. Airservices Australia’s Noise Action Plan for Brisbane demonstrates how assessment and community consultation can inform changes to flight paths and operating procedures.
With flights now underway, local leaders are encouraging residents to lodge formal noise complaints. Yet recording complaints is only the first step. Communities need to understand how that evidence is assessed and whether it informs operational changes where warranted.
The experience of other airports demonstrates that environmental management cannot end with project approval. It requires ongoing evidence, community engagement and a willingness to adjust operations as circumstances change. For a 24-hour airport near an internationally significant World Heritage landscape, that responsibility is particularly important.
From commitments to demonstrated outcomes
The original Western Sydney City Deal included commitments to performance reporting and review. Yet the Commonwealth’s published reporting currently lists 2021 as the latest Western Sydney progress report. The airport’s opening provides a timely opportunity to revisit those commitments and demonstrate how employment, transport and environmental outcomes are being delivered together.
These are not new challenges. Our earlier Wicked Urban Challenges in Western Sydney research highlighted the need for more coordinated responses to the region’s interconnected economic, social and environmental pressures. Those challenges also helped inspire the establishment of our Urban Transformations Research Centre in November 2022.
As we approach the Centre’s fourth anniversary on 4 November, we continue working with regional, national and international partners to connect research, policy and practice, recognising that many of the challenges facing Western Sydney are shared by rapidly growing metropolitan regions across Australia and beyond.
The opening of Western Sydney International Airport offers an extraordinary opportunity to put these principles into practice. Its long-term success will depend not simply on delivering a major infrastructure project, but on sustaining collaboration, adapting to new evidence and ensuring that economic, social and environmental ambitions advance together.
After decades of planning and anticipation, Western Sydney has much to celebrate. The opportunity now is to build on this historic achievement and realise its promise of a more connected, prosperous and sustainable region – with lessons extending well beyond Western Sydney.
