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.
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.
