Is it becoming more difficult to find affordable housing in your area?

Australia saw national construction costs rise by 3.2 percent in the year ending 30 September 2026, while the sector struggles to meet housing targets. The industry is currently 124,000 homes behind its five-year goal of 1.2 million units.

Why it matters

The ongoing Middle East oil crisis continues to inflate costs for fuel and material transportation, pressuring the construction industry. Additionally, intense competition for skilled labour from major infrastructure and data centre projects is further driving up expenses.

National construction costs rose 1 percent in the most recent quarter, with Western Australia and South Australia seeing annual growth of 3.6 percent and 3.5 percent respectively. Australia has completed 355,817 dwellings toward its 1.2 million goal.

The players

Western Australia

This state recorded the highest annual construction cost growth in the nation at 3.6 percent.

South Australia

This state experienced a 3.5 percent annual rise in construction costs alongside a 4.3 percent unemployment rate.

The details

Rising fuel prices and the cost of materials like plastic and Gyprock have placed significant upward pressure on project budgets nationwide. Competition for skilled tradespeople remains fierce, as large-scale infrastructure and data centre investments outbid standard residential projects.

March 2026 saw a 0.2 percent increase in construction costs.
30 September 2026 marked the end of the year with 3.2 percent annual cost growth.

Market Landscape

This trend mirrors the broader historical impact of supply-side fuel shocks, which often trigger cascading inflation across construction-heavy economies. The current environment positions residential builders against high-budget data centre projects that command premium labour and material resources.

The rising cost of materials and labour will likely translate into higher project budgets and increased pricing for new home buyers. Prospective homeowners may face longer construction timelines as residential builders struggle to compete for the limited pool of available skilled tradespeople.

The takeaway

Rising fuel and material costs are creating significant headwinds for Australia's housing supply goals. Homeowners planning new builds should prepare for potentially volatile quotes and extended timelines as the industry navigates persistent supply chain pressures.
