Australia’s Construction Cost Landscape in 2025
Construction costs across Australia continue to shift—and 2025 reflects another round of changes. Whether you’re building a new home or overseeing a large project, understanding the national price landscape gives you a clearer budgeting path. This section sets the context before we go city-by-city.
We’ll break down average construction costs per square metre, compare them with past years, and explain the trends behind the movement—backed by data from Altus Group, Quantity Surveyors, and the Australian Bureau.
What is the National Average in 2025?
The average cost to build a home in Australia in 2025 ranges between $1,900 and $4,300 per square metre, depending on the city, build quality, and project scope.
- The average cost has increased compared to 2023, driven by material shortages, wage growth, and inflation.
- Square metre pricing is highest in capital cities with constrained land supply.
- Reports from the Australian Bureau and Altus Group confirm the nationwide trend toward higher baseline costs.
- Across most states, the construction industry is under pressure from infrastructure demand and high-volume project backlogs.
Historical Comparison – 2023 to 2025
Costs have risen over the past two years, and the reasons are structural.
- Building costs increased as a result of inflation and interest rate hikes that affected financing for both builders and buyers.
- The post-COVID recovery caused rapid demand for housing, but supply chains failed to catch up.
- High emissions compliance and fuel costs added pressure across regional logistics.
- Labour shortages further pushed up the cost of project delivery in both urban and regional areas.
City-by-City Cost Breakdown (2025)
While national averages offer a baseline, real construction costs are shaped by where you’re building. Australia’s major cities vary significantly in terms of land prices, labour availability, and infrastructure demand. This section breaks down the 2025 costs across capital cities, helping you understand what to expect in each location.
From Sydney’s premium inner suburbs to Adelaide’s affordable growth zones, the variations are driven by market dynamics, regulatory settings, and geographic constraints. Here’s what each city looks like in numbers—and in context.
Sydney, NSW – Most Expensive Market
Sydney remains Australia’s priciest location to build, with costs pushed up by land scarcity and labour demand.
- Average construction cost: $3,200–$4,300 per square metre
- Inner suburbs attract a premium due to density and developer demand
- Outer metro areas are slightly more affordable, but still above national averages
- High labour costs and limited land supply continue to pressure budgets
Melbourne, VIC – Metro vs Outer Suburbs
Melbourne’s inner city shows signs of material-driven inflation, while outer regions offer value opportunities.
- Per square metre costs range from $2,700 to $3,800
- Metro areas face higher average costs due to complexity and developer competition
- Outer suburbs like Clyde and Werribee remain more accessible for new home builders
Brisbane, QLD – Growth and Affordability
Brisbane offers a strong balance of growth and cost-effectiveness, appealing to both homeowners and investors.
- Average cost per square metre: $2,400–$3,500
- Land is still competitively priced, especially in outer-ring suburbs
- Strong new home demand is driving local industry expansion
Adelaide, SA & Hobart, TAS – Most Cost-Effective
Both cities continue to offer some of the most accessible build rates in the country.
- Typical construction costs range from $1,900–$2,900 per square metre
- Less volatility in materials and wages supports stable pricing
- Popular with first-time builders and regional developers
Perth, WA & Darwin, NT – Logistics & Labour Pressures
Building in these remote cities brings additional transport and labour challenges that affect the bottom line.
- Costs range between $2,600–$3,800 per square metre
- Freight and delivery add to square metre pricing
- Labour shortages in regional zones increase project delays and costs
Major Cost Influencers in 2025
Understanding construction costs in 2025 means looking beyond averages. The real price of building is shaped by several moving parts—materials, labour, and land. These aren’t just numbers on a quote; they directly impact every project’s timing, budget, and feasibility.
This section breaks down the three biggest cost drivers affecting Australian construction right now. Whether you’re planning a new home or managing multiple sites, these are the forces pushing prices up—or keeping them in check.
Material Prices & Supply Chain
Volatility in key materials like steel, timber, and concrete is reshaping how projects are priced and delivered.
- Prices vary by location and distance from suppliers
- Import dependency increases exposure to global cost shifts
- Local sourcing is often limited or more expensive in remote areas
- Carbon-intensive materials are under scrutiny, with embodied carbon now a planning factor
Labour Market & Skilled Trade Availability
Australia’s skilled trade shortages are driving higher wages and longer project timelines.
- Labour costs are rising across most states
- Delays are common, especially in regional areas
- Wage expectations differ between metro and outer zones
- Fewer apprentices and skilled workers are entering the construction companies pipeline
Land Costs and Development Charges
Land acquisition and council fees continue to drive up baseline build budgets, especially in major cities.
- Land prices remain highest in Sydney, Melbourne, and Brisbane
- Local councils apply different zoning fees and developer contributions
- Infrastructure upgrades and density rules vary by LGA
- Government levies add complexity to house construction and lot development
Sustainability and Design Factors Driving Cost
In 2025, more Australian homeowners and developers are building with sustainability in mind—but eco-conscious design often comes with added upfront costs. While some choices reduce long-term energy use, others require a higher initial investment in materials, engineering, and certification.
This section breaks down how sustainability goals and design preferences influence construction costs. These are not just nice-to-haves anymore—they’re shaping how projects are scoped, priced, and delivered across every region.
Green Building and Energy Efficiency
Sustainable construction is no longer optional. Energy efficiency is becoming a minimum standard, and with that comes higher starting costs.
- Energy-efficient materials like double-glazing, solar, and insulation add to initial budgets
- Builders are incorporating low-carbon and carbon-neutral planning from day one
- Embodied carbon and carbon footprint are now tracked for both compliance and future-proofing
- Sustainable upgrades often pay off in lower long-term energy use
Design Complexity and Custom Builds
Unique designs bring character—but they also raise costs through additional detailing and structural planning.
- Custom homes involve more design complexity than standard spec builds
- Complex designs increase engineering time and reduce construction efficiency
- Higher material wastage and longer build times push budgets higher
- Builders must price in flexibility for unexpected design revisions
What to Expect: Future Construction Costs (2026–2028)
Looking beyond 2025, the key question is whether construction costs will continue to rise—or begin to stabilise. Forecasting isn’t about guesswork; it’s about tracking where housing demand, interest rates, and government policies are headed. These are the forces shaping what projects will cost in the next few years.
This section outlines where the market is likely going and what that means for builders, developers, and anyone planning to enter the construction industry between now and 2028.
Forward Signals to Watch
- Continued Pressure from Housing Demand
New home demand remains strong in growth corridors. Population increases and limited stock will likely keep prices from dropping. - Interest Rate Movement Will Remain a Wildcard
If interest rates ease, more buyers will enter the market—pushing up land and build costs again. If rates stay high, demand could soften. - Supply Chain Recovery May Take Time
Materials like steel and concrete are stabilising, but global disruptions and fuel costs could cause further delays or price bumps. - Policy and Regulatory Changes Matter
Increased focus on sustainability and emissions compliance could introduce new cost layers, especially around low-carbon building standards. - Inflation May Cool, But Not Disappear
General inflation is slowing, but the gap between wage expectations and project budgets may continue to drive construction costs higher. - Cost Stabilisation Could Vary by Region
Some cities may flatten earlier than others. Regional centres with lower average cost bases may see price plateaus before capital cities.
