Transfer duty and first-home concessions
Stamp duty in New South Wales or South Australia — what is the difference?
On a first home, up to $42,437 across the three prices below — and almost all of that gap is the first-home concession rather than the rates.
Same house, both states
| Price | New South Wales · first home | South Australia · first home | Difference |
|---|---|---|---|
| $600,000 | $365 | $32,977 | $32,612 |
| $750,000 | $365 | $42,802 | $42,437 |
| $900,000 | $17,708 | $52,627 | $34,919 |
And without first-home relief
| Price | New South Wales · next home | South Australia · next home | Difference |
|---|---|---|---|
| $600,000 | $21,552 | $32,977 | $11,425 |
| $750,000 | $28,302 | $42,802 | $14,500 |
| $900,000 | $35,052 | $52,627 | $17,575 |
What the two tables say
The first-home gap swings by $9,825 across these three prices ($32,612, $42,437, $34,919), while the next-home gap moves far less ($11,425, $14,500, $17,575). Concession policy is what makes the first-home figure volatile — who qualifies, up to what price, and how fast it tapers. The underlying scales differ too, and by more than people expect: even with no relief on either side, these two are $11,425 to $17,575 apart.
Both columns are computed by the same engine the calculator runs, on the 2026–27 scales, for a citizen or permanent resident buying an established home. Registration fees are included; legal fees, inspections and any foreign purchaser surcharge are not.
