Fifteenth Avenue redesign: Liverpool Council seeks extra $239m for six-lane boulevard

Residents and businesses along Fifteenth Avenue are facing a fresh contest over the corridor’s future after Liverpool City Council rejected Transport for NSW’s June 2026 design and sought an extra $239 million for its own six-lane transit boulevard proposal.

The council voted 6-4 to oppose the TfNSW design and request an additional 17 per cent from the state and federal governments. Its alternative has a proposed design speed of 70 kilometres per hour and includes a bridge over the upper canal.

Councillors said the redesign would reduce community impacts and construction costs. The resolution also calls for a more collaborative approach between Liverpool City Council, TfNSW and other project participants as concerns about the corridor are addressed.

Council approved $50,000 from the General Fund for a communications campaign targeting residents along or near Fifteenth Avenue. The campaign will promote the council’s advocacy for dedicated transport lanes and give affected residents an opportunity to provide feedback.

Liverpool City Council has spent approximately $1.7 million on its alternative proposal since 2017. About $1.5 million was spent on design investigations and a business case funded through the Special Infrastructure Contribution levy. Approximately $100,000 was allocated to communications and advocacy campaigns, while a further $140,000 was spent on a concept cross-section and costing exercise funded through the Australian Government’s Housing Support Program.

The council’s preferred design is separate from the Transport for NSW Review of Environmental Factors dated June 2026. The vote does not secure the requested funding or replace TfNSW’s design, so the corridor’s final layout, construction impacts and delivery timetable remain unresolved.

Fifteenth Avenue is linked to the Western Sydney Airport growth area. The competing proposals would produce different road layouts and construction effects for people who live and work along the route.
