Australian small and mid-sized construction manufacturers are experiencing a sharp downturn in revenue and profitability, as geopolitical tensions in the Middle East begin to ripple through global markets and supply chains.
New data from Unleashed’s latest Manufacturing Health Index, which analysed more than 500 Australian firms across sectors including construction, food and beverage, and apparel, shows construction manufacturing revenue has fallen to its lowest level since 2020.
Average revenue dropped to $391,941 in the first quarter of 2026, down from $716,237 in the previous quarter and representing a 54 per cent decline compared to the same period last year.
Profitability has also tightened significantly.
Gross margin for construction manufacturers fell to 26.3 per cent in Q1 2026, down from 35.3 per cent in Q4 2025 and marking the weakest margin since 2018.
The data suggests that rather than a collapse in activity, many firms are bracing for continued instability, shifting toward more cautious and defensive operating strategies.
Despite the downturn, some businesses report steady demand but rising cost pressures.
ThinTanks, an Australian manufacturer exporting slimline rainwater tanks globally, has seen sales increase in recent months, yet faces mounting input and freight costs due to its reliance on oil-based materials.
The company has implemented price increases to offset these pressures, with demand remaining resilient so far.
However, longer lead times mean the full financial impact of current market conditions may take weeks to materialise, adding uncertainty to forward planning.
ThinTanks CEO Peter Turner said: “In the past few months, sales have been increasing, but so have costs.
“As an oil-based product that we freight across Australia, our margins are under real pressure.
“That has meant pushing through price increases, but despite that, demand has held up well.
“It is difficult to know where things go from here.
Turner noted that the company operates on a six- to eight-week lead time, meaning there is a delay before current conditions are fully reflected in its financial results.
He added that changes in the global outlook can affect performance significantly, though conditions can also rebound quickly.
Turner also pointed out that during the COVID period, the business achieved record results as consumer spending shifted away from travel and into home renovation.
Inventory strategies are also shifting.
In the lead-up to 2026, many manufacturers had adopted lean, just-in-time stock management approaches.
Average stock on hand fell to $200,500 in Q1 2026 as businesses reduced warehouse holdings.
However, construction manufacturers diverged from this trend, significantly increasing inventory levels to $380,789, up from $108,800 in the previous quarter.
A similar pattern was observed in the industrial machinery and raw materials sector, suggesting a move to buffer against anticipated supply disruptions.
While supply chain disruptions have not yet fully appeared in the data, early indicators point to growing volatility.
Lead times shortened to an average of two weeks in Q1, but are expected to rise as global shipping conditions adjust.
Purchase order values have already dropped sharply across all sectors, falling to their lowest levels since 2018.
Sustained high energy prices, with Brent crude trading above US$100 per barrel, are increasing input costs and squeezing margins.
At the same time, interest rate hikes by the Reserve Bank of Australia, which lifted the cash rate to 4.1 per cent in March, are adding further pressure to businesses already managing inflation and labour shortages.
Manufacturers are increasingly turning to automation and real-time data tools to improve efficiency and navigate tighter purchasing cycles.
With geopolitical instability expected to persist, the ability to adapt quickly to cost pressures and supply fluctuations is likely to define which firms remain competitive in the months ahead.
