According to realestate.com.au, governments are raking in record property tax billions while the construction industry — the very sector needed to resolve the national housing shortage — is experiencing builder insolvencies at an alarming rate. The collision of maximum tax extraction and minimum building activity is not coincidental. It is a structural consequence of how Australian governments have chosen to fund their budgets, and it is making the housing crisis materially worse.
Record Property Tax Revenue While Builders Go Under
The federal and state governments' dependence on property-related taxes has reached a critical inflection point. Stamp duty, land tax, GST on new construction, development levies, and infrastructure charges are all simultaneously applied across the development pipeline — often before a single slab is poured. Each of these charges flows directly into the cost base of every new dwelling, inflating the price that buyers must pay and compressing the margin that builders can absorb. When costs spike — as they have during the post-pandemic materials and labour surge — margins evaporate entirely. Builders, particularly small-to-medium residential contractors, have no buffer left.
For property investors and developers assessing feasibility, this environment demands a hard look at the full tax stack before committing to any new construction project. Development application fees, infrastructure levies, and GST clawbacks — combined with land tax on unsold lots — can collectively add significant costs per dwelling to the base. Projects that modelled profitability at 2022 prices are now structurally unviable. For a full breakdown of how property taxes interact across the investment cycle, see our Australian Property Tax Guide.
How the Tax Stack Kills Construction Economics
The compounding effect of Australia's property tax architecture is most acute in new construction. A developer building a medium-density residential project faces GST on the sale price of new dwellings, land tax on the holding period of the site, infrastructure contributions to local councils, and stamp duty paid when the land was originally acquired. None of these charges shrink when construction costs rise. They are either fixed percentages of sale price or fixed dollar levies — meaning they consume a larger share of margin in a tight-cost environment. The builder caught in the middle has no mechanism to pass costs upstream to government.
This is why the framing of a government "addiction" to property tax is analytically precise rather than polemical. Tax dependency creates a political incentive structure where governments benefit financially from high property values — through stamp duty and capital gains — while simultaneously claiming to support affordability. These two objectives are mathematically incompatible. Higher property values mean larger tax collections. Lower property values — which genuine affordability reform requires — mean lower revenue. No state government has yet resolved this tension with a credible, revenue-neutral transition plan.
Investors assessing new-build opportunities should model tax costs explicitly at every stage: acquisition stamp duty, GST on purchase of a new dwelling, land tax during any development hold period, and capital gains tax on eventual disposal. Depending on the state, land tax alone on a development site held for an extended period can represent a significant drag on project returns. For investors using self-managed superannuation structures, the tax treatment differs again — underscoring why specialist advice is essential before committing capital to construction.

The Supply Shortfall: Taxes as a Structural Barrier
Australia's housing shortage is documented and severe. Federal and state governments have committed to ambitious dwelling targets, yet the tax architecture actively works against those targets. Development levies and infrastructure charges add directly to the cost of each new dwelling, making projects unfeasible in lower-price suburbs where the housing need is often greatest. Governments collect the levy, but the social cost — a unit that is never built — lands on the waiting list for social housing or the prospective first home buyer who cannot find affordable stock.
The builder insolvency wave compounds this supply gap in a way that takes years to unwind. When a builder goes into administration, partially completed projects stall, subcontractors absorb losses, and the industry's trained workforce disperses. Rebuilding that capacity — the trades, the project management systems, the contracted supply chains — takes far longer than a single budget cycle. Governments that extract maximum tax during a building boom, then watch the industry contract, cannot simply turn the tap back on when political pressure demands action. Supply-side damage is cumulative and slow to reverse.
Governments benefit financially from rising property values through stamp duty and land tax collections, yet simultaneously commit to affordability targets that require those values to fall — a structural contradiction that no state budget has yet resolved with a credible transition plan.

With the cost of carrying development finance already elevated, adding a heavy property tax burden to financing costs makes marginal projects unviable before a single approval has been granted.
What Investors and Developers Must Do Right Now
In this environment, investors considering new construction or development must treat tax cost modelling as a non-negotiable first step — not an afterthought. A feasibility study that excludes land tax holding costs, infrastructure contributions, and GST on sale price will produce a return projection that does not survive contact with reality. The gap between a pre-tax and post-tax return on a new-build residential project can be the difference between a viable investment and a capital destruction event.
Investors already holding development sites should review their land tax exposure state by state. New South Wales, Victoria, and Queensland all assess land tax annually based on unimproved land value — and with land values elevated across most capital city markets, many investors are sitting in higher tax brackets than they modelled at acquisition. Some states offer
