South Australia Property Market

South Australia's property market is anchored by Adelaide, which has seen strong price growth driven by defence industry investment, interstate migration, and relative affordability. Adelaide has emerged as a major growth city, with the AUKUS submarine program set to bring sustained high-income employment to the region.

Average Home Price A$680000
Avg Council Rates (annual) A$1800
Avg Building Insurance (annual) A$1500
Standard Variable Rate ~6.24%
Serviceability Assessment Rate ~9.24%

Buying in South Australia

Adelaide remains one of Australia's more affordable capital cities, though the gap with Sydney and Melbourne has narrowed. The SA economy offers competitive salaries in defence, manufacturing, and health sectors relative to housing costs. SA's land tax applies at rates up to 2.4% on investment properties.

Stamp Duty

South Australia charges stamp duty on a sliding scale. On A$680,000, the duty is approximately A$31,330. First-home buyers purchasing new homes may be exempt from stamp duty under the new home grant scheme. SA also charges land tax for investors on total landholding value.

Lenders Mortgage Insurance (LMI)

LMI is required when LVR exceeds 80%. SA's more moderate price growth relative to other capitals means LMI costs are typically lower in absolute dollar terms β€” usually A$4,000–A$10,000 at 85–90% LVR.

First Home Owner Grant

SA offers a First Home Owner Grant of A$15,000 for new homes. First-home buyers may also access stamp duty concessions for new homes and established properties under certain value thresholds.
