Up to 12,000 new homes are planned for Sydney’s northwest as areas are built up to complement a mammoth rail project.
Three new urban centres will be constructed around Kellyville, Bella Vista and Showground railway stations on the $8.3 billion North West Rail Link.
The NSW government says the hubs could create 19,000 jobs and 12,000 additional homes.
Public parks, cycle routes and green corridors will also be revamped.
The Baird Government will provide $15 million for local infrastructure in each precinct.
Planning Minister Pru Goward said the population in the Hills district was projected to increase by 100,000 by 2031.
She said in a statement it was vital local and state governments planned for the growth "so that there are a variety of different housing options and jobs for the children and grandchildren of the families who already call Sydney's northwest home."
The Property Council of Australia welcomed the vision in light of the "unprecedented" investment in the North West Rail Link.
"Escalating population growth in our west means we need to hasten investment in new housing and employment opportunities," NSW executive director Glenn Byres said.
