Stamp duty varies wildly across Australia — the same $800,000 property can cost you $10,000 in the ACT or $32,000 in NSW. First home buyers can save $10,000-$30,000+ through concessions, and some states are transitioning to annual land tax instead. 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.
