Western Sydney mayors have been brought to the table as the NSW Opposition develops plans for a new City Deal aimed at tackling the region’s mounting transport, housing and infrastructure pressures.

Opposition Leader Kellie Sloane and senior members of the NSW Liberal team met mayors and council representatives in Oran Park on Monday, seeking local input into a proposed new Western Sydney City Deal by 2028.

Representatives from Blacktown, Campbelltown, Camden, Fairfield, Hawkesbury, Liverpool, Penrith and Wollondilly councils were invited to the roundtable, with a future South Western Sydney Metro among the major issues on the agenda.

“Western Sydney is growing quickly, and local councils and mayors know where the pressure is being felt – that’s why we want their advice at the centre of our plan for a new Western Sydney City Deal,” Sloane said.

The proposal comes as planning intensifies around future rail connections through Sydney’s rapidly growing south-west. Government documents recently revealed potential stations for a southern Metro extension through Bradfield South, Maryland, Pondicherry, Oran Park, Narellan, Mount Annan and Macarthur.

Sloane said better connections within Western Sydney itself would be crucial as the region continues to grow.

“Western Sydney needs to be connected not only to the rest of Sydney, but also to itself, and that can only be done with targeted infrastructure that is developed and delivered in partnership with those on the ground,” she said.

The Opposition says its proposed City Deal would bring together federal, state and local governments, with housing and supporting infrastructure also forming part of the plan. Its commitment to pursue a new deal and progress a South Western Sydney Metro was announced in Ms Sloane’s June Budget Reply.

Deputy Liberal Leader and Shadow Transport and Infrastructure Minister Natalie Ward said the next phase of Western Sydney’s growth required long-term planning.

“Western Sydney deserves a clear plan for the decades ahead, shaped with its councils rather than a scramble for one-off grants,” Ward said.

The roundtable was also attended by Shadow Treasurer Scott Farlow, Shadow Local Government Minister Tim James and Shadow Planning Minister Chris Rath.
