The construction industry in Australia entered 2026 already absorbing multiple simultaneous cost pressures. Shannon Drew, Management Accountant and Fractional CFO at Blaze Business & Legal, has modelled the combined impact of six simultaneous cost inputs across client portfolios. The finding is consistent, in that the total uncontracted cost impact of the current fuel crisis on active projects is two to three times higher than the direct diesel number. What Shannon has found is that a business which has calculated its diesel exposure at $180,000 often finds its full-portfolio exposure increased to $395,000 by the time it takes these other five cost impacts into account.

Australian industry conditions declined materially in March, with the Australian Industry Index falling 19.9 points to -23.6, the steepest monthly fall since the initial pandemic phase of early 2020. Uncertainty was the main factor, with 30% of businesses reporting volatility in fuel prices, freight and supply arrangements. More than a quarter said rising costs were a major pressure across fuel, freight, raw materials, resins, plastics and packaging.

Construction, and civil in particular, is the most reliant Australian industry on diesel, contributing 79% of our energy. Civil Contractors Federation Australia has spoken to governments and national and state media about the rise in costs and the contract flexibility needed to work through the energy shock. Minimising price rises in maintenance and replacement costs of civil infrastructure requires the government working closely with the civil sector in the period ahead.

Diesel hit $3 a litre last week. We've got lump sum contracts locked in, purchase orders issued, and now suppliers are adding fuel levies or pushing back on supply unless prices move. Every path from here costs someone money that wasn't in the original deal.

For regional and civil contractors, the compounding effect is the biggest concern: fuel costs hit transport first, then materials, then every other input. There is no way to swap diesel out. It is what moves everything.

In recent weeks we have engaged with our supply chain, consultants and subcontractors to understand the real cost impact hitting active and pipeline projects. The picture is not uniform, but the direction is consistent, and the pace is faster than anything we saw coming out of COVID.

A national reef operator in Far North Queensland will see fuel expenses increase by $1 million dollars from February to end of financial year in June. Fuel shortages and fuel costs are impacting farmers, the tourism industry, and regional communities and small business owners. One in seven people in Far North Queensland are employed by tourism.
Bree James MPMember for Barron River, Queensland Parliament
Our phones have rung off the hook this week. We have had a flood of enquiries from builders wanting to introduce cost-escalation clauses, and from homeowners seeking advice because some builders are now trying to cancel contracts that were only just signed. If they make the wrong move, the consequences can be significant. The smartest thing anyone in the industry can do is slow down, understand their legal position, and avoid making reactive decisions under pressure.

Australia imports roughly 90 per cent of its oil, and the country's refinery count has fallen from eight to just two. The shift has left Australia increasingly exposed to global energy shocks. Energy Minister Chris Bowen confirmed six oil shipments bound for Australia in April were turned back or deferred due to escalating tensions. The government has alluded to a "national crisis."

$9 per litre diesel by July? Sounds ridiculous until you actually run the numbers. Australia runs on diesel. We've got 20 to 26 days of supply. We import 90%, refined in Asia, but the supply chain runs through the Middle East for around 48%. We are at the very end of that chain. With flows constrained at 25%, that is where pricing breaks. With flows stalled, you are looking at a 60-plus per cent shortfall, and fast. That is not expensive fuel anymore. That is access. Industries start to slow, or stop.

The current fuel security issue was entirely predictable and, in fact, comprehensively predicted. No recent Australian government can say it was not warned. The "fair-weather" approach that plagues Australia's fuel security could not contrast more starkly with the concerted action directed towards critical minerals. The 2014-15 senate inquiry into Australia's transport energy resilience examined the very issues in which the country is currently mired.
