All sites identified as part of the land audit are first offered to Homes NSW and Landcom, the NSW Government's developer.
Among the latest tranche of government-owned sites, three are in Greater Sydney and four are in regional centres.
In the Northern Tablelands region, Homes NSW are investigating the former Duval High School site in Armidale which has the potential for over 100 new social, affordable and market dwellings to support regional growth driven by the New England Renewable Energy Zone.
The site at Valla Beach, north of Nambucca Heads and close to the Pacific Highway, could yield more than 160 new dwellings. With sites at Boolaroo in the Lake Macquarie region and Broken Hill capable of delivering 190 new homes.
Among the newly announced Greater Sydney locations, the site at Whalan in the Blacktown local government area currently comprises lots which may support more than 120 new homes. Other sites in North Kellyville and Prairiewood could collectively provide around 19 new dwellings.
The Prairiewood site in particular is suited to low-rise housing using the Government's recently announced NSW Housing Pattern book, which offers high-quality architect designs supported by a 10-day planning approval pathway to make it faster and more affordable to design and build a home.
The specifics of housing delivery including the quantity and types of homes for all newly announced property audit sites will be available once due diligence, planning and regulatory approvals are complete.
Minister for Lands and Property Steve Kamper said:
"We are continuing to tackle the state's housing crisis head-on, these new sites, delivering more than 600 homes, continues our strong response to the housing supply crisis.
"The property audit program is delivering a steady pipeline of new housing development opportunities on unutilised surplus government land, to help address our critical shortage in housing supply.
"While stimulating housing supply in our urban centres is critical, we have also been able to identify key sites in regional cities such as Broken Hill and Armidale to deliver much needed housing to our regional communities."
Minister for Planning and Public Spaces Paul Scully said:
"As the land audit continues to unlock land for new homes, the Minns Government is identifying sites that suit the NSW Housing Pattern Book designs and their 10-day approval pathway so builders can get straight on with building.
"As we tackle our housing supply challenges, we want to make sure there are homes that are well-designed, sustainable and adaptable to a range of lifestyle choices."
Minister for Housing and Homelessness Rose Jackson said:
"Our land audit is delivering real results. Approximately ten thousand potential homes identified in just over a year shows the scale of what is possible when government gets serious about housing supply.
"We are making sure surplus public land is put to work for the community, not left sitting idle. Every one of these sites has the potential to deliver hundreds of homes where they are needed most.
"This is about more than numbers. From Armidale to Broken Hill to Sydney's west, these projects will mean more people can afford to live near work, near family, and with the security of a roof over their head.
"Whether it is social housing, affordable rentals or market homes, we are determined to build every type of housing people in NSW need. That is the only way to tackle the housing crisis and give people a fair shot at a secure home."
