Wollondilly mayor Robert Khan is calling for money from the state government's WestInvest fund to be spent in the shire.
Earlier this month the Premier Gladys Berejiklian announced $5 billion from the government's sale of its residual 49 per cent stake in WestConnex would be used in western Sydney.
Ms Berejiklian said the announcement was "about helping to rejuvenate local communities with improved parks, better open spaces, giving town centres a boost and providing opportunities to grow".
"The future of Western Sydney is bright and this announcement is a major first step along the road to recovery after a challenging year," she said.
And Cr Khan wants a slice of the funding to be used on infrastructure projects in the shire to support local jobs and economic recovery for Wollondilly.
"Wollondilly Council is calling on the NSW Government to invest in priority infrastructure for our growing community," he said.
"Boosting housing supply is the biggest economic priority for the NSW Government, and the best way to boost housing supply is to invest in infrastructure needed for growing communities.
"Our new town in Wilton is here now and growing every day as more families move in. We're calling on the NSW Government to use WestInvest to fast-track planned infrastructure including public transport, schools, water supplies, health and recreational facilities."
Cr Khan said there were several key projects in the shire in need of immediate funding.
"We need an electrified rail line to both Picton and Wilton to connect us to other major centres and make sure our current and future residents have safe and accessible transport options," he said.
"The Picton Bypass is also a key priority which would connect the growing Thirlmere and Tahmoor with Wilton and provide emergency bushfire evacuation to avoid the shocking scenes in 2019 when our roads were gridlocked as the bushfires approached.
"Investment in tourism infrastructure such as the Great Burragorang Valley Walk would also be a huge boon for our area.
"The WestInvest fund is an opportunity for the state government to provide this significant infrastructure now, so it can be in place before our population increases further.
"This investment would also create jobs that will boost our local economy following the challenges of bushfires, floods and COVID-19 our community has experienced over the last two years."
