How Stamp Duty Works in South Australia
In South Australia, stamp duty is administered by RevenueSA. It's a state tax applied to the purchase of real property and certain other dutiable transactions. Duty is calculated on the greater of the property's purchase price or its market value and is typically paid at settlement through your conveyancer.
SA uses a progressive rate schedule with marginal rates increasing at each threshold. South Australia recently raised its first home buyer exemption threshold significantly, making it one of the most competitive states for entry-level buyers.

First Home Buyer Concessions in SA
South Australia offers some of Australia's most generous first home buyer stamp duty relief:
- Full exemption on properties up to $650,000 for eligible first home buyers
- No stamp duty payable at all for properties under this threshold
- Properties over $650,000 attract standard rates with no FHB concession
To qualify, you must be an Australian citizen or permanent resident, at least 18 years old, and have not previously owned residential property in Australia. You must also intend to live in the property as your principal place of residence within 12 months of settlement.
Note that from 2024, South Australia increased the FHB threshold from $500,000 to $650,000, providing substantial additional relief in a market where median house prices in Adelaide have risen significantly.
Worked Examples
Example 1 — First Home Buyer, $600,000 Home
| Item | Amount |
|---|---|
| Purchase price | $600,000 |
| Standard duty (at $500k+ rate) | $24,830 + 6.5% of $100,000 = $31,330 |
| FHB exemption (under $650k threshold) | –$31,330 |
| Duty payable | $0 |
This first home buyer saves over $31,000 — one of the most generous exemptions in the country.
Example 2 — Owner-Occupier, $450,000 Home
| Item | Amount |
|---|---|
| Purchase price | $450,000 |
| Duty: $12,830 + 6.0% × ($450k – $300k) | $21,830 |
| Duty payable | $21,830 |
As this buyer is not a first home buyer, standard rates apply.
Example 3 — Foreign Buyer Purchasing $700,000 Property
| Item | Amount |
|---|---|
| Purchase price | $700,000 |
| Standard duty (over $500k rate) | $24,830 + 6.5% of $200,000 = $37,830 |
| Foreign surcharge (7% of $700k) | $49,000 |
| Total payable | $86,830 |
Foreign purchasers face a substantial additional cost in SA.
Foreign Purchaser Duty Surcharge
Foreign purchasers of residential property in South Australia pay an additional duty surcharge of 7% of the dutiable value on top of standard stamp duty rates. A foreign person is defined as someone who is not an Australian citizen or permanent resident, or a corporation with foreign ownership.
The surcharge applies to residential land only. Exemptions may be available for New Zealand citizens holding special category visas, and for certain circumstances such as acquisitions by Australian citizens living abroad temporarily.
