Stamp duty varies wildly across Australia — the same $800,000 property can cost you around $13,600 in the NT or $43,000 in VIC. First home buyers can save even more: ACT abolished stamp duty entirely for first home buyers from July 2026 (no cap), and several other states offer six-figure exemptions. This calculator compares every state and territory side by side so you can see exactly how much you'd pay — and potentially save — when buying property in Australia.
