What the numbers actually look like right now

Every figure below is computed by the same engine that powers the calculators on this site, against rates published by each state revenue office. It is our own research, not a summary of someone else’s.

Duty computed with the ozfinancecalc engine against published state rates, 26 July 2026.
Stamp duty payable by an owner-occupier buying an established home at each city’s median dwelling value.

Buying the median home costs $51,139 in stamp duty in Sydney and $27,188 in Canberra — a spread of $23,951 on properties that are, in each case, simply the middle of their own market. As a share of the purchase price, duty runs from 3.07% to 5.39% depending purely on which side of a state border the property sits.

Two things about that surprise most buyers. The first is that seven of the eight capitals give a first home buyer no duty relief at all on an established home at the median price — the concession thresholds now sit below what a median home costs. Only Canberra does, because the ACT abolished first home buyer conveyance duty outright on 1 July 2026, with no value cap and no income test.

The second is that duty is rising faster than prices. Brisbane values rose 17.4% over the year while the duty on them rose 31.1%, because the brackets are not indexed. Perth was 23.9% against 30.0%. That gap is not a policy anyone announced; it is simply what happens when prices move and thresholds do not.
