Why Australian renovation costs keep outpacing inflation

Construction costs in Australia and the rest of Asia-Pacific are set to keep climbing faster than general inflation, and the increases look structural rather than temporary, according to RE Talk Asia, reporting on JLL's Global Construction Costs Index 2026.

What the report found

JLL forecasts construction tender prices across Asia-Pacific will rise 3.8% to 4.7% in 2027—running close to North America (3.2% to 4.2%) and ahead of Europe (2.2% to 3.5%). The drivers, per the report, include disruption to Middle East energy and materials supply chains, acute skilled-labour shortages, land scarcity in major cities, and surging demand for specialised construction tied to data centres and advanced manufacturing.

Two points stand out for Australian homeowners. First, construction cost inflation here has run well ahead of the Consumer Price Index: the report puts it at roughly 1.5 times CPI since 2021. Second, trades wages across the region's key markets rose between 8% and 35% from 2020 to 2026, outpacing both consumer prices and material costs—a gap JLL's Shweta Choudhari describes as a "structural shift rather than a temporary disruption."

Materials most exposed, according to the report, are steel, aluminium and cement—all energy-intensive and reliant on supply chains running through Middle East trade hubs. JLL's advice to developers is not to wait for relief: "Postponing projects in hopes of relief is no longer viable," said Matt Bennion, the firm's Head of Project and Development Services for Asia-Pacific.

What it means for your renovation

For households, the practical takeaway is similar: prices for labour-and-materials-heavy jobs are unlikely to fall, and some categories are more exposed than others.

• Steel and aluminium-heavy jobs. Metal roofing, Colorbond fencing and garage doors, and aluminium-framed solar panels all draw on the materials JLL flags as under the most sustained price pressure. A metal roof replacement currently runs around $15,000 for a mid-range job ($11,700 – $19,500), against $13,400 for concrete tile at the basic end. See the full breakdown at Roof replacement.
• Cement-heavy jobs. Driveways, rendering and foundation work all lean on cement, another material the report singles out. A new driveway typically costs $7,200 ($5,600 – $9,350); see New driveway for surface options.
• Labour-heavy jobs. Kitchen and bathroom renovations are dominated by skilled trade hours rather than materials, so wage growth feeds through more directly. A mid-range kitchen renovation is currently $20,000 ($15,600 – $26,000), and a bathroom renovation $22,000 ($17,100 – $28,500). Full guides: Kitchen renovation and Bathroom renovation.
• Solar and electrical work. Solar installations combine aluminium framing with licensed electrical labour—both named pressure points in the report. A 6 kWp system is currently $8,900 ($6,950 – $11,600); see Solar panels for battery add-on pricing. Remember that Australian solar and heat pump hot water quotes are usually shown after the federal STC discount, which steps down each year until the scheme winds up in 2030—so the underlying equipment cost is rising even where the out-of-pocket price looks stable.

None of this means every job gets more expensive at the same rate. Jobs with a higher share of imported, energy-intensive materials—metal roofing, Colorbond fencing, EV charger cabling, aluminium window frames—sit closer to the pressures JLL describes than jobs dominated by finishes and labour, like interior painting or flooring.

How we calculate our figures

We build our cost estimates from labour hours multiplied by local trade rates, plus current materials pricing, then check the result against market data and real quotes from Australian tradespeople. We update these figures as costs move, rather than relying on a fixed survey from a point in time—so the live shortcodes on this site should already reflect most of the pressure JLL is describing, rather than lagging behind it.

What homeowners can do

If you're planning a renovation that leans on steel, aluminium or cement—a new roof, fencing, a driveway or solar—getting quotes locked in sooner rather than later is reasonable given the trajectory JLL describes, since nothing in the report points to prices easing. For labour-heavy jobs like kitchens and bathrooms, the bigger lever is trade availability: in tight markets, a wider spread of quotes is worth more than usual.

Whatever the job, it's worth checking any quote against current typical ranges before you sign. If you've already got a number from a tradesperson, our "is my quote fair" tool can tell you how it stacks up against local, up-to-date pricing—useful context given that, per this report, waiting for costs to come back down to older benchmarks isn't a realistic strategy for 2027.
