The state government in New South Wales has released more land in southwest Sydney to enable 3200 new houses to be built there.
Premier Barry O'Farrell on Saturday announced that land at Catherine Field will go on sale from 2014, with houses available in 2015.
"We're releasing the land that people need ... but also at the same time delivering the schools, sewerage lines, the local roads, the major roads but also the railway lines," Mr O'Farrell said.
AAP reports Planning Minister Brad Hazzard said it was the seventh major rezoning undertaken by the state government in three years.
"The critical issue to drive down prices is the availability of houses," he said. "Turning paddocks into opportunities for people to have homes is what this government is about."
He estimated up to a million people would move to southwest Sydney by 2031.
