On 25 March 2026, South Australian Premier Peter Malinauskas announced a landmark change designed to support older South Australians, which will in turn stimulate housing supply and free up larger family homes across the state.
Under the newly signed policy, eligible downsizers aged 60 and over, will no longer pay stamp duty when purchasing a qualifying new home, off‑the‑plan apartment, or land to build; potentially saving up to $103,830.
If you’re considering downsizing, or simply want to understand how this policy works, read on to find out everything you need to know.
To summarise, you must:
- Be 60 years or older
- Sell your existing principal place of residence
- Purchase a new or off‑the‑plan home to live in
- Buy a property valued at $2 million or less
- Downsize into a smaller property
- Enter into a contract on or after 25 March 2026
- Use the exemption only once
What Is the New Stamp Duty Relief for Downsizers in South Australia?
The SA Downsizer Stamp Duty Relief is a full abolition of stamp duty for eligible people aged 60 years or older who are selling their current home and downsizing into a newly built or off‑the‑plan property.
Unlike previous concessions, this policy removes stamp duty entirely, meaning no transfer duty is payable if all eligibility criteria are met. The policy forms part of the Malinauskas Labor Government’s broader housing strategy to:
- Increase housing supply
- Encourage housing mobility
- Free up larger homes for growing families
- Support older South Australians transitioning into their next stage of life
When Does the Downsizer Stamp Duty Relief Start?
The exemption applies to contracts signed on or after 25 March 2026, the date the Premier announced and signed the instrument.
More broadly, the policy is aligned to come into effect once the re‑elected Labor Government is formally sworn in, with implementation expected in the first week of April 2026.
If you enter into a contract before this date, the exemption will not apply.
Who Is Eligible for the Stamp Duty Exemption?
To qualify, you must be 60 years of age or older at the time you enter into the contract. There is no upper age limit, and the policy is designed to support older homeowners looking to downsize into a more suitable property.
Do I Need to Sell My Current Home?
Yes. To access the stamp duty relief, you must sell your existing principal place of residence and purchase a smaller property to live in. This ensures the policy supports genuine downsizing and helps return larger homes to the market for families.
What Does “Downsizing” Mean Under This Policy?
Downsizing means moving into a property that is smaller than your current home. This could include:
- A smaller block of land
- A lower overall dwelling size
- An apartment instead of a detached house
The intent is to encourage more efficient use of housing stock, particularly in the established Adelaide metro areas.
What Types of Properties Are Eligible?
Existing homes do not qualify under this policy. To receive stamp duty relief, you must purchase one of the following:
- A newly built home
- An off‑the‑plan apartment
- Land to build a new home
The property must be brand new and purchased with the intention of living in it as your principal place of residence.
Does the Property Have a Price Cap?
Yes. The maximum property value is $2 million. This cap ensures the exemption supports genuine downsizers rather than high‑end property transactions or investment activity. If the purchase price exceeds $2 million, the exemption will not apply.
How Much Stamp Duty Could I Save?
Eligible downsizers could save up to $103,830 in stamp duty.
This is a full abolition in stamp duty, not a reduction or partial concession. If you meet the criteria, you simply pay no stamp duty on the transaction.
For many downsizers, this represents one of the largest cost barriers being completely removed.
Can I Claim the Downsizer Exemption More Than Once?
No. The stamp duty exemption can only be accessed once. This reinforces the policy’s purpose as a one‑time transition incentive, rather than an ongoing tax benefit.
Why Has the Government Introduced This Policy?
The main purpose of the Downsizer Stamp Duty Relief policy is to address one of the biggest financial roadblocks preventing older homeowners from downsizing.
By abolishing stamp duty, the policy aims to:
- Encourage older residents to move into homes that better suit their lifestyle
- Unlock larger homes for families who need space
- Boost construction of new and off‑the‑plan dwellings
- Improve housing mobility across the state
How Does This Help First‑Home Buyers and Families?
When downsizers move into smaller, newer homes, it often frees up family‑sized homes in established suburbs, including properties close to schools, transport and employment hubs.
This creates a flow‑on effect that benefits first‑home buyers and growing families, without the need for new land releases alone.
What Are the Benefits of Downsizing Under the New Exemption?
The new stamp duty exemption removes one of the biggest financial barriers to downsizing, allowing eligible homeowners to retain more of their equity by paying no stamp duty on a qualifying purchase.
New and off‑the‑plan homes also tend to offer lower maintenance and running costs due to modern construction and improved energy efficiency.
For many downsizers, moving into a smaller, well‑located property closer to transport, medical services and lifestyle amenities can also deliver a more convenient and manageable day‑to‑day lifestyle.
Does This Policy Apply to Couples?
Yes. Couples can qualify provided at least one purchaser is aged 60 or over, the eligibility requirements are met and the home is downsized compared to their current residence.
What Should Downsizers Do Next?
If you are considering downsizing in South Australia, now is the time to:
- Review your current home’s value
- Explore suitable new or off‑the‑plan options
- Seek legal and financial advice before signing a contract
- Ensure the contract date aligns with the policy start
Final Thoughts: Is the SA Downsizer Stamp Duty Relief Worth Taking Advantage Of?
For eligible South Australians, this policy represents one of the most generous stamp duty reforms ever introduced in the state.
With potential savings of over $100,000, reduced ongoing costs and improved lifestyle outcomes, the incentive to downsize has never been stronger.
If you’re aged 60 or over and planning your next move, this policy could significantly change your financial position — and your options.
