Stamp Duty in Western Australia
Western Australia's stamp duty rates sit in the middle of the pack nationally. The progressive bracket system starts at 1.9% and rises to 5.15% for amounts over $725,000. Perth's more affordable property market means stamp duty is often lower in absolute terms than eastern capital cities.
