Stamp duty (officially called conveyance duty) is often the biggest cost after your deposit. In South Australia it's paid to RevenueSA when you buy a property, and it's worked out on the purchase price or the property's value, whichever is higher.
SA uses a sliding scale, so the rate rises with the price. As a guide, for a standard buyer:
| Purchase price | Approximate stamp duty |
|---|---|
| $500,000 | $21,330 |
| $800,000 | $37,830 |
| $1,000,000 | $48,830 |
Above $500,000, every extra dollar attracts duty at 5.5%, so it's worth budgeting for early.
Eligible first home buyers pay no stamp duty when they buy:
There's no value cap. There's currently no stamp duty concession for first home buyers purchasing an established home, so the standard rates apply.
From 25 March 2026, South Australians aged 60 and over who sell their home and buy a new or off-the-plan home valued up to $2 million can receive a full stamp duty exemption. Eligibility rules apply, so check with RevenueSA or your conveyancer.
Investors pay the standard rates. Remember to factor in ongoing land tax too, which applies to investment properties in SA once the land value passes the threshold.
