| $30,001 – $50,000 | $480 + 3% of the amount over $30,000 |
| $50,001 – $100,000 | $1,080 + 3.5% of the amount over $50,000 |
| $100,001 – $200,000 | $2,830 + 4% of the amount over $100,000 |
| $200,001 – $250,000 | $6,830 + 4.25% of the amount over $200,000 |
| $250,001 – $300,000 | $8,955 + 4.75% of the amount over $250,000 |

The table above shows the standard scale. South Australian first home buyers purchasing a newly built or off-the-plan home are fully exempt from duty with no price cap; established homes get no such relief. The 7% foreign buyer surcharge is charged separately on the full value.

| Transfer registration (approx.)Land titles office | $6,638 |
| Mortgage registration (approx.)Land titles office | $204 |
| Government cost at settlement | $97,522 |
The same property bought by an Australian citizen or permanent resident (as an investment) would cost about $36,422 in government charges — a difference of $61,100 entirely from the surcharge and the FIRB application fee.

Common questions
What is the South Australian foreign buyer surcharge?
The foreign ownership surcharge is 7% of the dutiable value of residential land, paid alongside stamp duty. On $650,000 that is $45,500.
Is the SA first home exemption really uncapped?
Yes, but only for newly built or off-the-plan homes, and only for Australian citizens or permanent residents who will live in the property. Established homes are not covered.
Can foreign buyers purchase property in Adelaide?
They can buy new dwellings, off-the-plan property and vacant land with FIRB approval. Established dwellings are generally off limits during the ban from April 2025 to June 2029.
Does South Australia charge foreign owners a land tax surcharge?
No. South Australia taxes foreign buyers on the way in — the 7% duty surcharge — but adds nothing to the annual holding cost. General land tax still applies on taxable site value, on the same basis as for local owners.
Is the rate the same for a company or trust?
The surcharge is apportioned to the foreign interest; foreign companies and foreign trusts are also charged 7%. FIRB fees are calculated separately by entity type.
