Australia Needs More Homes. So Why Are Its Builders Vanishing?

Australia has set itself an ambitious target: 1.2 million new homes in five years under the National Housing Accord. It's the kind of number that's supposed to fix the housing shortage everyone agrees is driving up rents and locking out first home buyers. There's just one problem: the industry meant to build those homes is shrinking, not growing.

Nearly 7,800 construction businesses have left the industry nationally since the Accord began in 2024, more than 3,200 of them in NSW alone. In the most recent financial year, 1,540 NSW construction companies went into external administration, a record. Nationally, 3,472 construction firms failed, with NSW accounting for almost half.

That's not a rough patch. That's an industry that's structurally struggling to build the thing the country most needs.

Why builders keep going under

It isn't one problem, it's several stacked on top of each other. Land is expensive before a single brick is laid, and by the time a builder adds construction costs, infrastructure contributions and taxes, the numbers on a lot of proposed projects simply don't work. Government fees and charges alone are estimated to make up around 40% of the cost of a new home.

Add to that tighter lending conditions and slow approvals, fixed-price contracts signed before materials and labour costs spiked, an ongoing shortage of skilled tradespeople, wafer-thin margins with no financial buffer for a bad year, and the ATO ramping up debt recovery after a pandemic-era pause, and it becomes clearer why so many builders simply can't hold on. Industry figures from the HIA and Urban Taskforce point to the same conclusion: in NSW, only about 2% of projects that go through feasibility actually get financial approval to proceed. Ninety-eight percent don't make it.

Each collapse also causes more collapses. When a builder goes under, the subcontractors and suppliers who were relying on payment often go down with them, which is part of why the failure rate keeps compounding rather than stabilising.

The gap between the target and the timeline

NSW alone is meant to deliver 377,000 homes by June 2029 under the Accord. On current trends, that completion date has already slipped to around March 2032, nearly three years late. Meanwhile only around 35,000 new homes were completed in NSW in the last financial year, even as building approvals rose 6% year-on-year. Approvals are up; completions are down. That gap between paperwork and finished homes is exactly where the housing shortage keeps compounding.

Western Sydney is a particularly sharp example: expensive land, a shortage of development-ready sites, heavy infrastructure costs, and buyers who are increasingly priced out of what it would actually cost to build there.

What this means if you're buying, building or investing

The most immediate consequence is upward pressure on rents, especially in established suburbs where supply simply isn't keeping pace with demand, and that pressure isn't going away quickly, even if construction costs eventually stabilise. It takes years to rebuild an industry's capacity once experienced builders, tradespeople and subcontractor networks have exited.

For anyone considering an off-the-plan purchase, this is a risk that deserves real scrutiny, not just excitement about a display suite. A builder or developer going into administration mid-project can mean long delays, cost blowouts passed on to buyers, or in the worst cases, a project that never gets finished. Before signing anything off-the-plan, it's worth digging into the builder's financial position and track record, understanding exactly what protections your contract and deposit actually have if the builder fails, and treating any price that looks unusually good as a reason to ask more questions, not fewer.

Against that backdrop, established properties in strong locations look more attractive by comparison. Replacement costs keep climbing: it now genuinely costs more to build a comparable home than it did a couple of years ago, and well-located existing homes carry an increasing margin of safety that a new-build promise on paper doesn't.

The bottom line

The housing supply everyone is counting on isn't just a policy target. It depends on a construction industry that's currently contracting under the weight of its own costs. Until land supply, approval times, and the fee burden on new homes genuinely improve, the gap between what's promised and what actually gets built is likely to persist. For buyers and investors, that argues for real caution around off-the-plan exposure and a renewed case for the reliability of quality, established property in the meantime.
