One of the most significant land parcels to become available in Adelaide’s south in recent years is now on the market.
Renewal SA has launched a single-stage Request for Proposal (RFP) for a development partner to deliver up to 1,000 homes across 67.6 hectares of greenfield land within the City of Onkaparinga, representing an estimated $750 million in completed market value.
This constitutes approximately half of the potential new homes for the area, with an adjacent site earmarked for a further 1,000 homes to be delivered through private development.
It also marks a continuation of Renewal SA’s investment in the southern suburbs, complementing major residential developments already underway at Noarlunga and undergoing planning at Aldinga.
“This is a rare opportunity for a major development partner to shape a new community in one of South Australia’s most sought-after regions,” said Shane Wingard, Renewal SA Executive Director, Property and Major Projects.
“We are inviting local developers and those from across the country to leverage South Australia’s favourable economic conditions and strong housing demand.”
South Australia was recently ranked the nation’s second strongest economy in the CommSec July 2025 State of the States report, driven by rising consumer spending, business investment and dwelling starts.
Located 32 kilometres from the CBD, Onkaparinga Heights is close to Seaford Meadows Train Station, bordered by Main South Road and Piggott Range Road, 15 minutes from McLaren Vale and Port Noarlunga beach, and close to the Onkaparinga River and national park.
The site is positioned at the start of Adelaide’s North-South Corridor, a 78-kilometre non-stop motorway due for completion in 2031, connecting the southern and northern suburbs, with direct CBD access via multiple exits.
Previously part of Hackham and Old Noarlunga, the area was renamed Onkaparinga Heights following a major rezoning in early 2023, which transformed 235 hectares of Rural Land into a Master Planned Neighbourhood Zone.
“Onkaparinga Heights sets the scene for a bright future in Adelaide’s south,” Mr Wingard said.
“With connectivity to the city, world-renowned beaches close by, nearby schools, hospitals, shopping districts, and outstanding hospitality, Onkaparinga Heights is poised to be one of the state’s leading new residential locations.”
Renewal SA is seeking experienced development partners with a shared vision for the area.
“This presents an amazing opportunity in the southern metropolitan market for a developer that is aligned with Renewal SA’s vision to deliver a high-quality, community-focused, master-planned project,” he said.
“From a developer perspective it’s also notable that the southern market is very tight, with limited supply and competition we know that the demand in this market is very strong.”
Renewal SA will be seeking a minimum of 20% affordable housing, to be sold through HomeSeeker SA or delivered via a Community Housing Provider.
Proposals integrating aged-care and innovative housing types are also encouraged.
Infrastructure deeds, signed in December 2024 between the state government and surrounding landowners, provide infrastructure solutions through delivery and cost sharing, and enable planning, engineering and land division to start early and with certainty.
A long-term wastewater solution has been identified to enable a coordinated development outcome.
“The infrastructure deeds provide certainty for developers around infrastructure delivery,” Mr Wingard said.
"A developer will know they can hit the ground running to a deliver a project at speed."
Mr Wingard expected the market would be buoyed by Renewal SA’s strong track record in delivering successful housing developments, including one just down the road at Noarlunga.
“Our 626-home Noarlunga development, just 5 kilometres away, is going very well, receiving strong market interest and excellent early sales results,” he said.
Last year, Renewal SA also announced a partnership with Villawood Properties to deliver around 800 homes across a 45-hectare site, 16 kilometres further south in Aldinga, following a two-stage market process. Renewal SA has since streamlined this market process, with only one stage proposed before a developer will be appointed.
According to realestate.com.au, surrounding suburbs including Seaford, Hackham, Huntfield Heights, Old Noarlunga, Seaford Meadows and Onkaparinga Heights have an average median house value of $746,000 and experienced a 13% growth in value over the past 12 months.
The RFP is open for eight weeks, closing at 2pm (ACST) Thursday 9 October.
