SA’s development land sales continue to boom
Demand for housing is fuelling multimillion-dollar SA land transactions with the aged care sector also on the hunt. See what the new SA data reveals on sales and trends.
South Australia’s development land sector continues to build with Adelaide-based Colliers’ Investment Services team transacting over 185,000 square metres of land so far in 2025, with an additional 15,000 square metres expected to come to market soon.
The high demand for housing across the state has influenced the market, with residential and accommodation development sites accounting for 89 per cent of all Colliers’ transactions, with the other 11 per cent made up of commercial and retail opportunities.
Research from Colliers contributed population growth, interstate migration and other factors to the surge in residential focused land transactions.
Associate Director at Colliers Rhys Newman said the high volume of land transactions – valued at approximately $60 million – was a “clear indicator of market confidence”.
“Despite broader economic headwinds, developers are continuing to invest in projects that align with the state’s growing need for housing and mixed-use precincts,” Newman said.
Recent data from Colliers showed that 48 per cent of South Australian home buyers were actively seeking new and recently built homes.

Government incentives such as the First Home Owner Grant – a one off payment of $15,000 to eligible first homeowners who are building or buying new residential properties – and the removal of stamp duty for first home buyers have increased the demand in new property development.
“Ongoing demand for labour in the state and recent changes to first home buyer policies—including adjustments to deposit and stamp duty requirements—are also contributing to heightened activity, making residential development sites even more attractive to investors and developers,” Newman said.
Colliers said these incentives had further fuelled the demand for greenfield estates and master-planned communities.
There had been strong interest on recent listings including a 5240 square metre block at 113 Liguria Crescent in Noarlunga Downs.
The Noarlunga Downs suburb had experienced a 14.3 per cent median house price growth over the past 12 months with increased demand for property in Adelaide’s southern corridor.
The site has a maximum building height of three levels with minimum allotment sizes starting from 150 square metres.

Another sale attracting keen interest was a 2,310 square metre site located on 243-253 Halifax Street in the heart of Adelaide’s south-eastern CBD.
The land is desirable for both investors and owner-occupiers and comes with zero stamp duty, vacant possession and the ability to generate short-term income from the existing improvements.
The Halifax Street site is zoned City Living, with up to three stories allowed under development opportunities.
The street had become a sought-after CBD location for both residential and office opportunities, with Colliers recently selling 32 Halifax Street site which is set for a $6.9 million redevelopment of townhouses.
Both CBD and Noarlunga Downs sites reflect the growing trend for scalable residential projects in both metropolitan and suburban locations, Newman said.
Newman said the aged care and retirement living sector was “aggressively pursuing” land located alongside traditional residential developers.
“The sale of 12–16 Glen Osmond Road, Parkside for $9.6 million—set to become a new aged care accommodation project—is a prime example of this trend,” he said.
Other notable transactions for Colliers included the 11,772 square metres residential development site on the intersection of Magill Road and Portrush Road.
“With strong fundamentals and a clear demand trajectory, Adelaide’s development land market is expected to remain active throughout the remainder of 2025, led by residential and accommodation-focused projects,” Newman said.
