A major new infrastructure package from the NSW Government is set to fast-track critical enabling works across the Western Sydney Aerotropolis.
The $835 million package aims to help turn the 11,200-hectare region into a freight and industry powerhouse.
Unveiled in the 2025-26 NSW Budget, the investment spans roads, water and emergency services infrastructure, and builds on more than $5 billion already committed to the area.
The funding includes $644 million for Sydney Water’s delivery of stormwater and recycled water networks across the 1,020-hectare Mamre Road Precinct – the first to be developed within the Aerotropolis.
This includes naturalised channels, wetlands, and stormwater basins, replacing traditional concrete infrastructure in what Sydney Water says is Australia’s largest integrated stormwater scheme.
The investment is expected to catalyse industrial development by reducing upfront costs for developers. After negotiation with the state, Sydney Water has dropped its proposed bond fee from $1.3 million to $877,000 per hectare in its final Development Servicing Plan, released in May.
On the transport front, more than $148 million in new funding will boost the road network supporting the Western Sydney International (Nancy-Bird Walton) Airport, set to open by late 2026.
Key allocations include:
- $50 million for signalisation at high-congestion intersections, including Elizabeth Drive-Luddenham Road and Mamre Road–Kerrs Road
- $39 million for planning three new routes – Devonshire Road, Devonshire Link Road, and Bradfield Metro Link Road – with $12.5 million from the federal government
- $29.6 million for a new incident management and response unit to minimise delays on key freight corridors
- $30 million for over 1000 green directional signs across Sydney to support airport and precinct access
This adds to ongoing co-funded projects such as the $1 billion Mamre Road Stage 2 upgrade, $800 million for Elizabeth Drive, and the $2 billion toll-free M12 Motorway.
Premier Chris Minns said the Aerotropolis would “deliver jobs, homes and opportunity for generations to come”, while Roads Minister Jenny Aitchison emphasised the focus on “must-have priorities – new and widened roads, intersections, safety upgrades – that will bust congestion”.
In emergency services, $42.2 million has been allocated for the new Badgerys Creek Fire Station on Adams Road, Luddenham. Set to be Western Sydney’s largest, it will house 52 new firefighters and three trucks, enabling 24/7 coverage and rapid response near the airport.
The station is expected to be operational by late 2026.
