If you’ve ever wondered why building a new home in Australia is so expensive, you’re not alone. Recent research commissioned by the Housing Industry Association (HIA) and prepared by the Centre for International Economics (CIE) found that almost half the cost of a new house-and-land package in Sydney comes from taxes, government charges, infrastructure contributions and regulatory costs. According to the report, these costs amount to around $576,000, representing 49% of the purchase price of a typical new home in Sydney.
These costs involve much more than a single tax. Buyers may indirectly contribute towards GST, transfer duty, developer contributions, planning requirements, infrastructure charges and various compliance costs incurred during the development process. While these charges help fund public infrastructure, such as roads and utility connections, they also increase the final price of new homes. Sydney has the highest proportion of government-imposed costs among Australia’s major capital cities, although the percentage varies across the country.
Government Charges That Can Affect the Cost of a New Home
| Cost Category | How It Can Affect Buyers |
| GST and transfer duty | Increase the overall purchase cost of new property transactions. |
| Infrastructure contributions | Development costs may be reflected in the final sale price. |
| Planning and regulatory requirements | Approval processes and compliance costs can increase development expenses. |
| Holding and financing costs | Longer approval timeframes may increase costs that are ultimately passed on to buyers. |
Anyone buying land or building a new home should understand the contract just as well as the purchase price. House-and-land packages, building contracts, GST treatment and contract timing can all affect the overall cost. Obtaining professional conveyancing advice before signing any documents can help identify potential issues and ensure you understand your legal obligations before construction begins.
