Two new communities will be created in Sydney providing more than 13,000 homes for nearly 39,000 people.

At Marsden Park, about 40 kilometers from the Sydney CBD, more than 10,000 new homes will be built for nearly 30,000 people near the northwest rail line.

An adjoining industrial park being built has the capacity for 17,000 new jobs.

Four new schools are also planned for the area.

At Catherine Field, 3100 new homes are planned for 9000 people near the south west rail line.

The site will have a neighbourhood centre, with three new schools planned.

The O’Farrell government’s Housing Acceleration Fund will provide for infrastructure upgrades, said planning minister Brad Hazzard.
