Infrastructure Australia has added a north-south rail connection across Western Sydney to its 2026 Infrastructure Priority List - the independent, evidence-based blueprint that tells the Federal Government where to direct nationally significant investment over the next decade.
The proposed line would connect St Marys to Tallawong in the north, with extensions from Bradfield south to Leppington and Macarthur. Together, these corridors would form a high-capacity transport spine linking the region's major growth nodes into a single network.
For anyone holding, buying, or developing land in the Bradfield precinct, this is worth paying attention to.
Why This Matters
Infrastructure Australia's Priority List is not a wish list. Inclusion requires rigorous, evidence-based assessment and signals that a proposal warrants serious consideration for federal funding. The north-south rail link now sits alongside the country's most strategically important infrastructure proposals.
Western Sydney hosts the nation's third-largest regional economy by Gross Regional Product. Its population is growing faster than any other corridor in NSW. And with Western Sydney International Airport opening this year, the pressure on north-south transport capacity across the region is acute - something the existing road network cannot solve alone.
The Western Sydney Regional Organisation of Councils (WSROC) has backed the announcement, with President Councillor Brad Bunting noting that strong north-south rail connections are essential to link people with jobs, education, and services across the region.
What This Means for Property in Bradfield
Transport infrastructure drives land value. That's not opinion - it's the pattern behind every major corridor uplift in Sydney over the past two decades. And the effect starts well before construction, once planning clarity and political commitment firm up.
The Priority List inclusion provides exactly that kind of signal.
At BIRE, we've seen growing enquiry from domestic and international buyers drawn to Bradfield's long-term fundamentals. Infrastructure commitments of this nature are what give buyers the confidence to move and investors the certainty to commit capital.
The proposed rail extensions would connect Bradfield south to Leppington and Macarthur and north through St Marys to Tallawong - effectively expanding the catchment of buyers and tenants who can realistically reach the precinct by rail. That has direct implications for demand, yields, and long-term values.
BIRE is currently marketing land within the Bradfield precinct that stands to benefit directly from this corridor, including 122 Mersey Road, Bradfield, 16 Kelvin Park Drive, Bradfield, and 19 Derwent Road, Bradfield.
"The inclusion on Infrastructure Australia's Priority List is the clearest planning signal we've had that the north-south corridor is being taken seriously at a national level. For buyers in Bradfield and surrounding precincts, this is the kind of long-term certainty that changes where you put your capital."

The Airport Connection
Western Sydney International Airport opens this year. But the airport's full economic impact - and that of the surrounding Aerotropolis - depends on a public transport network that reaches communities well beyond the immediate precinct.
The north-south rail spine would do exactly that: linking the airport to established and emerging communities from Tallawong to Macarthur. Penrith City Council Mayor Todd Carney has stressed the importance of maintaining pace on rail delivery, noting the region's potential depends on clear transport connections across the full corridor.
What Happens Next
Priority List inclusion is a nationally significant milestone, but it's not a funding commitment. The north-south rail link is one of approximately 60 proposals on the list. What's now required is firm government funding to move from planning to delivery.
Key steps ahead include corridor protection to safeguard future rail alignments, business case refinement, precinct planning and density uplift around proposed stations, environmental assessment, and continued advocacy from councils and industry to secure funding.
The Australian Government committed $1 billion last year to secure rail corridors enabling future extensions between the Aerotropolis, Leppington, and Macarthur - a foundation on which further investment is expected to build.
The north-south rail link is no longer aspirational. It's operating within a nationally recognised planning and investment framework. For landowners and investors in the corridor, the window between planning signal and price response is where the opportunity sits.
"Rail connectivity is the piece that turns Western Sydney's growth story into a property market reality. The north-south link would make Bradfield genuinely accessible to the whole of Sydney - and that changes everything for demand and development feasibility."
