$835m investment to deliver major Western Sydney Aerotropolis infrastructure

A comprehensive $835 million is being invested to enable further development of the Western Sydney Aerotropolis as well as support jobs creation and maximise economic growth in the region. 

The Aerotropolis spans 11,200 hectares and it represents a generational opportunity to create a thriving economic hub that will provide thousands of new jobs closer to home for the people of Western Sydney. 

This funding builds on the previously announced $1 billion investment – jointly funded with the Australian Government – to deliver the first stage of the Fifteenth Avenue upgrade. 

“With billions of dollars now committed, we’re not just talking about building a new airport – we’re creating a connected, thriving region that will deliver jobs, homes and opportunity for generations to come. 

“This funding ensures the right infrastructure is in place to support growth and unlock the full potential of the Aerotropolis. 

“Whether it’s new roads, or enabling infrastructure, we’re laying the foundations now to support the Aerotropolis into the future,” Premier Chris Minns said. 

“This Budget makes the critical investments in essential infrastructure to support new growth in Western Sydney. 

“We are backing the Aerotropolis precinct with the infrastructure to grow a local economy and create jobs. 

“This Budget puts opportunity at the heart of government decisions as we build a better future for NSW,” Treasurer Daniel Mookhey said. 

This year’s Budget includes about $150 million in additional funding for road infrastructure projects that will cater for the growing freight movement while maximising the region’s growth. 

The road infrastructure funding is in addition to the $2.55 billion allocated to existing Aerotropolis road projects over four years. This takes the total commitment to $2.7 billion. 

Key new project allocations include: 

• $50 million for critical road upgrades across the Aerotropolis, including traffic lights and signals at the Elizabeth Drive and Luddenham Road intersection and a new turning lane at the Mamre Road and Kerrs Road intersection 

• $39 million to plan three key routes – Devonshire Road, Devonshire Link Road and Bradfield Metro Link Road – including $12.5 million contribution from the Australian Government 

• $29.6 million for an incident management and response team to deploy rapidly to accidents and traffic delays. The new team will support key routes to and from the airport, along with the broader South Western Sydney road network 

• $30 million for more than 1,000 new green directional signs across Sydney directing to the Aerotropolis and Western Sydney Airport 

The new funding allocation for the projects above builds on major ongoing projects in the Aerotropolis, jointly funded by the State and Australian Governments, including: 

• $1 billion for the first stage of the Fifteenth Avenue upgrade between Liverpool and the new airport 

• $1 billion for the upgrade of Mamre Road Stage 2 between Erskine Park and Kemps Creek 

• $800 million for the upgrade of Elizabeth Drive to connect the new airport 

• More than $2 billion for the toll-free M12 Motorway 

“This year’s roads Budget includes close to $150 million in additional funding to support the Aerotropolis. We have focused on the must have priorities – new and widened roads, intersections, safety upgrades – that will bust congestion in this growing area. 

“We’ll ensure that ahead of the new Western Sydney Airport opening by the end of 2026, we’re building the supporting road network it needs,” Minister for Roads Jenny Aitchison said. 

The New South Wales Government is also delivering Western Sydney’s biggest fire station, which will be located on Adams Road in Luddenham. 

Construction on the Badgerys Creek Fire Station is anticipated to commence later this year and be completed by late 2026. 

In line with this project, the State Government is recruiting 52 new firefighters to staff the 24/7 station. $42.2 million is being allocated for this recruitment that will significantly expand the region’s firefighting strength and help deliver on an election commitment to fund 600 additional firefighters. 

This builds on the New South Wales Government’s $15.4 million investment last year to deliver the new Badgerys Creek station, including three new fire trucks. 

This investment in the 2025-26 State Budget is on top of an additional $17 million over two years to help renew the state’s firefighting and strengthen frontline emergency response. 

“Today marks an important investment in safety and resilience for Western Sydney. 

“Badgerys Creek Fire Station will play a vital role in strengthening our emergency response in this rapidly developing corridor. 

“This investment means our emergency services are prepared to help safeguard the community as the region continues to grow,” Minister for Emergency Services Jihad Dib said. 

“The fire station’s proximity to the airport means it can immediately respond and support aviation firefighters in any emergency. 

“It’s also a reflection of our ongoing commitment to firefighter wellbeing through modern design and safety-focused infrastructure,” FRNSW Commissioner Jeremy Fewtrell AFSM said. 

Lastly, Sydney Water is investing $644 million to deliver stormwater and recycled water infrastructure across the Mamre Road precinct in Western Sydney. This will be delivered as part of the largest integrated stormwater scheme in Australia. 

This project will support the development of the first precinct in the Aerotropolis – the 1,020-hectare Mamre Road Precinct – and lay the foundation for the remaining 7,267 hectares of industrial land surrounding the future Nancy-Bird Walton Airport. 

The State Government has worked with Sydney Water to drive down the cost to developers, giving them certainty while helping them get started with job-creating construction projects. 

Sydney Water proposed a bond fee for the Mamre Road Precinct of $1.3 million per hectare in March 2023 and has since then worked with the New South Wales Government to revise the scope, resulting in an $877,000 contribution in the final Development Servicing Plan that was released last month. 

Under the direction of the Minns Labor Government, this investment will help deliver the critical infrastructure needed to support growth across the Aerotropolis. 

The significant investment will fund: 

• The construction of naturalised channels and waterways (instead of concrete pipes and drains) 

• Land acquisition and construction of stormwater capture and harvesting infrastructure in the form of basins and wetlands 

This funding is part of the State Government’s plan to deliver better essential services that people and businesses rely on as well as to unlock investment to grow the economy to set New South Wales up for long-term prosperity. 

“The Minns Labor Government is committed to delivering for the people of Western Sydney, after the Liberals and Nationals allowed infrastructure projects in Western Sydney to stall. 

“These investments will ensure families and businesses are supported with the services they need to thrive. 

“With the new Western Sydney Airport set to open next year, it is vital we continue to invest in Western Sydney, so the area’s potential can be unlocked,” Acting Minister for Western Sydney Courtney Houssos said. 

“This significant infrastructure investment is about getting the basics right so we can build the homes and businesses Western Sydney needs,” Minister for Water Rose Jackson said.
