The country’s construction sector is operating near record levels, driven by a strong pipeline of public and private projects across housing, commercial property and large-scale infrastructure. A major industry consultancy reports that engineering work tied to solar, wind and hydro as well as large water upgrades is playing a central role, while a rebound in residential building, especially apartments, has lifted activity after a softer period. Non-residential projects are steady overall, supported by ongoing demand for data centres, hospitals and aged care facilities.
Beneath the headline growth, the sector is facing a complicated mix of cost and funding pressures. The conflict in the Middle East is emerging as a key risk, with the potential to disrupt shipping routes and push up prices for diesel, bitumen, steel and cement. About 20% of global oil supply moves through a critical shipping chokepoint in the region, so persistent instability could lift energy and freight costs, which then flow directly into construction budgets. At the same time, the risk of further interest rate rises is looming large, and modelling from the consultancy suggests that if the official cash rate climbs to 4.35%, total construction work done over 2026‑27 to 2029‑30 could end up roughly $42bn, or about 3.5%, below earlier forecasts.
Cost escalation, which had cooled in 2025, now appears to be picking up again. Building construction costs rose at an annualised pace of around 4.9% in the second half of that year, and house-building costs have started to climb after a brief dip in late 2024 and early 2025. Persistent shortages of skilled labour, from trades to engineers and site managers, are adding pressure, while limited competition among major contractors and ongoing insolvency concerns are making it harder and more expensive for developers to get large jobs off the ground. Even so, the national project pipeline still looks solid, with states such as Western Australia, South Australia and Queensland seeing faster approvals and project starts as both governments and investors push ahead with major schemes.
Looking ahead, the industry seems to be entering a period where healthy demand and tight capacity collide. The consultancy expects construction costs to rise by roughly 4–6% nationally in 2026, with stronger increases forecast in cities like Adelaide, Brisbane, Darwin and Perth and in growing regional hubs such as the Gold Coast and Townsville where activity is particularly intense. If geopolitical tensions ease and oil prices stabilise, some of the worst-case cost outcomes may not eventuate, but if conflict drags on and rates remain high, Australia’s construction boom could shift from record expansion to a slower and more selective phase where only the most resilient and well-funded projects move forward.
