Stamp duty, registration & GST.
Pick where you are buying, enter the property value (the higher of your price and the government guidance value), and see the true all-in cost of acquiring it, including GST for under-construction property. Runs privately in your browser; figures are indicative.
GST applies only while a property is under construction. Ready homes and plotted land carry no GST.
