Australia’s road freight sector is under mounting pressure as high diesel prices and supply issues cut into business confidence, fleet capacity and cash flow, with small operators and owner-drivers bearing the heaviest impact.
The NatRoad 2026 Fuel Crisis Survey, conducted during April 2026, shows the fuel crisis is no longer a future risk for road freight operators. It is already affecting the ability of many businesses to keep trucks on the road, retain staff and accept work.
According to NatRoad, the conditions created by soaring fuel prices and supply issues have rapidly reduced demand, capacity and the sustainability of road freight businesses, particularly small fleets and owner-operators.
The survey found a dramatic collapse in business confidence since March 2026. Before March, 54 per cent of respondents described their financial performance as very strong or strong. After changes to fuel excise and road user charges, only four per cent described their potential financial performance in the same positive terms.
At the same time, the proportion of operators describing their position as weak or very weak rose sharply, from 10 per cent before March to 69 per cent under current conditions. NatRoad described this as a 93 per cent decline in positive business outlook compared with the period before March 2026.
The impact is already being felt in operating capacity. The survey found 38 per cent of respondents had taken trucks off the road, while 40 per cent had declined or cancelled jobs due to the high cost of diesel since March 2026.
Small operators appear to be the most exposed. NatRoad said operators with fewer than 10 trucks face the most immediate risk of closure and accounted for 75 per cent of respondents who had already taken trucks off the road. Most small operators reported losing between 10 and 50 per cent of their business, while some had already shut down entirely.
The workforce impact is also becoming visible. One in four operators, or 26 per cent, reported reducing their workforce. More than 70 per cent of those businesses were small fleets with fewer than 10 trucks.
The survey also points to a broader sustainability issue for the industry. NatRoad reported that 68 per cent of respondents were at risk of closure within six months, while 83 per cent were at risk of closure within 12 months if conditions persist.
Cash flow emerged as the most critical financial issue for operators. NatRoad said many respondents described cash flow as “non-existent” or severely strained because fuel bills needed to be paid before customer payments were received.
That pressure is being compounded by payment delays, inflexible credit limits, rising input costs and tax obligations. The survey found 64 per cent of respondents reported other financial pressures affecting their business during the fuel crisis.
The survey also highlighted the human impact of the financial strain, with mental health concerns frequently mentioned by respondents alongside business stress. NatRoad said several responses indicated severe distress.
The findings show the fuel crisis is not only affecting profitability. It is reducing available road freight capacity at a time when transport operators remain critical to supply chains across the economy.
The pressure on smaller operators is significant because they make up an important part of the freight network, often servicing regional communities, specialised customers and subcontracted freight tasks that larger fleets may not cover as flexibly.
The NatRoad survey was open from 1 April to 30 April 2026 and received responses from 252 operators nationally. Of the respondents, 44 per cent were owner-operators with one to two trucks, 45 per cent were small and medium-sized operators with three to 19 trucks, and 11 per cent were large operators with 20 trucks or more.
NatRoad said the results demonstrate that road freight businesses are already experiencing reduced capacity, with small operators under 10 trucks being hit hardest.
The message from the survey is clear: rising diesel costs and supply instability are forcing operators to make immediate decisions about trucks, staff and jobs. For many, the issue is no longer whether margins are tight, but whether the business can continue operating.
