An alternative design for the Fifteenth Avenue corridor upgrade could spare 90 brand new homes from resumption and cut the project’s price tag by roughly $1 billion, Liverpool City Council announced on 2 July 2026.
The council’s proposal delivers a dedicated public transport lane from the outset and challenges the current $2.5 billion State and Federal plan, which builds a road-only Stage One and pushes mass transit into a later phase that would resume houses in Austral, West Hoxton and Middleton Grange.
Mayor Ned Mannoun said the choice facing governments is stark. “No family should lose their home because of a design that we already know is flawed and short-sighted,” he said. “We have a solution that saves money, protects homes, and delivers better infrastructure.”
Fifteenth Avenue has been a congestion and safety flashpoint for years. The link between Liverpool’s CBD and the emerging Western Sydney International Airport and Bradfield city centre carries thousands of newer households, many built in the past five years under housing targets that now sit squarely in the project’s path.
The council’s Fifteenth Avenue Smart Transit corridor vision, long advocated in petitions and ePetitions, is being pitched directly to both levels of government ahead of construction contracts.
“This is not about party politics, it’s about people,” Mannoun said. “We are calling on both the State and Federal governments to put aside differences of political opinion and do it once and do it right for the residents of Austral, West Hoxton, Middleton Grange and wider Western Sydney.”
The numbers behind the council plan are tight. The existing two-stage project is priced at $2.5 billion. Council modelling puts its alternative at roughly $1.5 billion, with the transit spine adding about $250 million, or 17 percent of the overall cost. That compares with a Stage Two that would later bolt on mass transit and trigger the loss of about 90 homes.
The design is more than a budget exercise. The council’s version embeds a transit lane from day one, avoiding the “gold-plated” high-speed road approach of Stage One. Without it, the council argues, the corridor will hit capacity within a decade, forcing another disruptive and expensive retrofit.
Mannoun tied the plan to the airport and Bradfield city. “Western Sydney cannot afford another decade of stop-start planning and political point scoring,” he said. “Fifteenth Avenue is not just a road. It is the spine connecting Liverpool to the Western Sydney International Airport and the emerging Bradfield city.”
The council is asking residents to contact their local State or Federal MP to advocate for the alternative. For families in the corridor’s path, the proposal determines whether their home survives a growth wave that is already reshaping street patterns each month.
A common misconception is that the current plan is locked in. Council modelling indicates the road-only Stage One would face capacity failures within a decade without the integrated transit. The later addition of mass transit, meanwhile, is the part that would trigger home resumptions.
