How Construction Costs Have Changed in Australia Over 5 Years

Published 26 June 2026 · Last updated 26 June 2026

Quick Answer

Over the past five years, construction costs in Australia have risen significantly due to factors like increased material prices, labour shortages, and supply chain disruptions. These changes impact project budgets and timelines, necessitating strategic planning for investors and developers.

Understanding how construction costs have evolved over the last five years in Australia is crucial for investors and developers planning new projects. This period has seen significant shifts due to various economic and global factors.

Key Trends in Construction Costs Over the Last 5 Years

Construction costs in Australia have been on an upward trajectory over the past five years, influenced by several critical factors. One of the primary drivers has been the increase in material costs, particularly for steel and timber, which have risen due to global supply chain disruptions and increased demand. Labour shortages, exacerbated by restrictions on international mobility and competition for skilled workers, have further inflated costs. Additionally, energy prices and regulatory changes have contributed to rising expenses. A common misconception is that these cost increases are uniform across all regions and project types; however, variations exist depending on local market conditions and project specifics.

How This Works in Practice

Consider a developer planning a mid-rise apartment complex in Melbourne in 2018. The initial budget was $10 million. Over the project timeline, construction costs surged by around 20% due to increased material prices and labour costs. By 2023, the project budget needed to be adjusted to $12 million. This increase directly impacted the project's financial viability and required strategic adjustments, such as renegotiating contracts and reassessing timelines, to maintain profitability. At a 37% marginal tax rate, the additional costs could potentially lead to increased depreciation claims, offering some relief.

Professional Insight

In our experience, one thing developers often underestimate is the impact of fluctuating material costs on their overall budget. Projects that seemed financially sound five years ago may require significant re-evaluation today. Another trend we've observed is the rising importance of sustainable building practices, which can initially appear costly but offer long-term savings and compliance benefits. What most investors don't realise is that the timing of purchasing materials can significantly impact costs; buying in bulk during off-peak periods can offer substantial savings. Additionally, engaging with a Chartered Quantity Surveyor early in the project can help identify potential cost-saving measures that are often overlooked.

When Does the Answer Change?

  • Regional Variations: Construction costs can differ significantly between urban and regional areas due to variations in local labour availability and transportation costs.
  • Project Type: Costs for residential projects have risen differently compared to commercial or industrial projects, often due to specific material and regulatory requirements.
  • Economic Conditions: During periods of economic downturn, such as the COVID-19 pandemic, some costs may have temporarily stabilised or decreased due to reduced demand.
  • Sustainability Requirements: Projects with a focus on sustainability might face higher upfront costs but benefit from long-term savings and incentives.
  • When Should You Seek Professional Advice?

    Determining the exact impact of construction cost changes on your project requires professional advice. A Chartered Quantity Surveyor can provide detailed cost assessments and forecasts tailored to your specific project, while an accountant can advise on tax implications and potential savings. Engaging these professionals early can help avoid costly mistakes and optimise your investment.

    What to Do Next

  • Review Your Project Budgets: Ensure they reflect current market conditions and adjust for any potential increases.
  • Engage a Quantity Surveyor: Obtain a comprehensive cost assessment to identify potential savings and risks.
  • Monitor Market Trends: Stay informed about material and labour cost trends to anticipate future changes.
  • Consider Alternative Materials: Explore cost-effective and sustainable material options.
  • Negotiate Contracts Wisely: Lock in prices where possible to mitigate future cost increases.
  • Plan for Contingencies: Allocate a contingency budget to cover unexpected cost overruns.
  • Frequently Asked Questions

    How have material costs changed?

    Material costs, particularly for steel and timber, have increased significantly due to global supply chain issues and heightened demand over the past five years.

    What has been the impact of labour shortages?

    Labour shortages have led to increased construction costs and longer project timelines, as competition for skilled workers drives up wages.

    Are there regional differences in construction costs?

    Yes, construction costs can vary significantly between urban and regional areas, influenced by local labour markets and transportation expenses.

    How do these changes affect tax returns?

    Increased construction costs may lead to higher depreciation claims, offering potential tax benefits. Consult your accountant for specific advice.

    How can I mitigate rising construction costs?

    Mitigate rising costs by locking in prices early, exploring alternative materials, and engaging a Quantity Surveyor to identify cost-saving strategies.
