On Thursday 4 June 2026, South Australian Treasurer Tom Koutsantonis handed down the 2026-27 State Budget, with a continued focus on health and housing.

Net debt is estimated at $34.7b in 2025-26 and is forecast to rise to around $53.7b by 2029-30, largely driven by funding for major infrastructure projects and long-term investments.

While the labour market remains strong, employment growth is forecast to slow to around 1 per cent per year through to 2029-30, after recording 3.25 per cent in 2025-26.

Inflation remains above the target range but is expected to ease and return to the RBA’s 2-3 per cent target band by mid‑2027.

Key spending highlights

  • $500m for an Apartment Fast‑Track Fund, as part of the Government’s $2.5b housing plan update.

  • $319m in additional funding for the administrators of the Whyalla steelworks.

  • $250m to a no-interest loan scheme to help deliver 650 new aged care beds.

  • An additional $50m to the Digital Investment Fund.

  • $26.8m over five years towards South Australia’s AUKUS skills workforce.

  • $18.5m for more affordable IVF treatment.

  • $16m to expand the Patient Assistance Transport Scheme.

  • $13.2m to expand the 24-hour pharmacies.

  • $8.4m for the expansion of Seniors Card program for South Australian seniors.

  • $1m in 2026-27 to pause increases in metroCARD public transport fares.

Revenue measures 

The South Australian Government revenue measures focus on improving housing accessibility, particularly for downsizers and vulnerable individuals.

Downsizing stamp duty concession

The Government is progressing with its election commitment to provide stamp duty relief for eligible downsizers of property. Under the concession, stamp duty relief of up to $103,830 for individuals aged 60 years and over who sell (or have sold) their principal place of residence, and downsize to a replacement property with a smaller land size is available.

The relief applies where the replacement property is a newly built home, an off the plan apartment, or vacant land on which a new home will be constructed. Eligibility applied to contracts entered into on or after 25 March 2026.

Full relief is available where the dutiable value does not exceed:

  • $2m (new homes or off-the-plan apartments); or
  • $1.2m (vacant land).

Partial relief applies where the dutiable value is:

  • between $2m and $2.1m (new homes or off-the-plan apartments); or
  • between $1.2m and $1.3m (vacant land).

Stamp duty relief for victims of domestic, family and sexual violence

The Government has introduced a new ex gratia scheme providing stamp duty relief to support victim-survivors seeking to re-establish themselves in secure, independent housing through building another home or purchasing an existing home.

Under the scheme:

  • Eligible applicants may receive 100 per cent stamp duty relief on the purchase of a new or established home.
  • Applicants may also access the First Home Owner Grant for eligible new homes or vacant land, even where they have previously owned property.

Savings for first home buyers

The 2026-27 Budget does not introduce any changes to the existing first home buyer regime. The First Home Owner Grant remains at $15,000 for eligible new homes, and the full stamp duty exemption for eligible first home buyers purchasing or building new residential properties remains unchanged.
