2026-27 South Australian Budget Update

Key measures for homeowners over 60, housing, and business

The Government delivered its 2026-27 budget on 4 June 2026, maintaining its commitment to “no new taxes”.

It focussed on housing affordability and strategic spending in key sectors such as education, research and development, and the wine industry.

Stamp Duty Relief for Downsizing

Announced prior to the budget, stamp duty relief will apply on a new replacement property acquired by an applicant aged 60 years or over where the replacement property is:

• acquired under a contract entered into on or after 25 March 2026;
• less than $2.1m for new homes and off-the-plan apartments; and
• less than $1.3m for vacant land.

The applicant must intend for the property to be their principal place of residence and the replacement property must have a smaller land size.

The existing property must be owned by at least one applicant.  The property must have been used as their principal place of residence prior to entering into the contract for the new acquisition and be sold 12 months before or after settlement of the replacement property.

Applicants must reside in the new property for a continuous period of at least 6 months commencing within 12 months from settlement (for new homes) or the earlier of 12 months from when you can lawfully use the residence or 36 months (for vacant land).

Other Budget Measures

There were numerous other spending measures announced at election time and in this budget, including:

• $50m for a new R&D productivity fund;
• further funding for making public schooling free;
• continuation of stamp duty relief and First Homeowners Grant for first homeowners;
• expansion of seniors card for all residents over 60. This includes free metropolitan public transport and other benefits;
• a rent to own plan for eligible housing applicants
• $1bn into two housing ‘fast-track’ funds including $500m committed for the government to act as guarantor for up to 50% of CBD apartment developments; and
• $800k over 4 years as an extension to the Project 250 wine program administered by South Australian Wine Industry Association.

The continuation of ‘no new taxes’ is welcome for South Australian businesses still trying to come to terms with the impact of tax changes announced in the Federal Budget.
