Fueling the Debate: Why Truck Fuel Tax Matters to Everyone

By Steven Ballerini | CEO of Australasian Supply Chain & Logistics Association (ASCLA)

In early 2026, a controversial recommendation from the Productivity Commission pushed Australia’s trucking and logistics industry into the spotlight. The proposal centres on significant changes to the Fuel Tax Credit Scheme, including phasing out credits for heavy vehicles operating on public roads. If implemented as outlined, the effective tax paid on truck fuel would more than double over time.

Industry groups such as the Australian Trucking Association have responded with strong concern, warning of serious consequences for freight operators and the broader economy. At the same time, policy commentators and infrastructure analysts have pointed to the wider fiscal and environmental context in which this recommendation has been made.

At the heart of the issue is the way fuel is taxed in Australia. Businesses currently pay fuel excise at the point of purchase but are able to claim back a portion of this through fuel tax credits. For heavy vehicle operators, this effectively means they pay a net road user charge rather than the full excise. This arrangement recognises that trucks are both major users of public roads and essential to the movement of goods across the country.

Under the fuel tax credits system, trucking operators pay an effective fuel tax rate of 32.4 cents per litre rather than the full rate, although this has increased to 52.6 cents per litre as of Monday 2 February.

The Productivity Commission’s report recommends removing these credits for heavy vehicles travelling on public roads. Under this scenario, the effective fuel tax for trucking operators would rise sharply over time and could exceed sixty-six cents per litre within the next decade.

Why the Productivity Commission Recommended the Change

The Commission has framed this recommendation as part of a broader reform agenda. It argues that the current fuel tax credit system subsidises fossil fuel consumption and distorts market signals that might otherwise encourage a shift to lower emission transport options. By removing or reshaping these credits, the Commission believes the tax system could better align with environmental objectives while also addressing what it sees as an inefficient and expensive concession.

From a policy perspective, the argument is that tax settings should encourage more efficient behaviour. If fuel is priced closer to its true cost, operators might be more inclined to adopt new technologies or reconsider transport choices where alternatives exist.

However, this view assumes that viable alternatives to diesel are already available at scale for heavy freight. That assumption is where much of the tension in this debate lies.

The Industry Response

The trucking industry has reacted swiftly and firmly. The Australian Trucking Association has described the proposal as a direct threat to operators who are already dealing with rising costs, driver shortages and tight margins.

Fuel is one of the largest variable costs in road freight. Even modest increases in diesel prices have a measurable effect on operating costs. A doubling of the effective tax rate would represent a significant and sustained cost increase that many operators would unlikely be able to absorb.

Industry leaders have also pointed out that the current system ensures that trucking businesses pay for their road use through the road user charge. Removing fuel tax credits would mean that operators effectively pay both a road charge and the full excise, which they argue amounts to double charging for the same activity.

There is also strong scepticism about the idea that higher fuel taxes will drive rapid decarbonisation. Long distance freight, heavy haulage and regional logistics remain heavily reliant on diesel. Electric and hydrogen alternatives are still emerging and face substantial challenges around cost, range and infrastructure.

Impact on Freight Operators

For freight businesses, particularly small and medium operators, the proposed changes present a genuine financial risk. Many operate in highly competitive markets where there is limited capacity to pass on cost increases to customers or adjust existing contractual arrangements, including the way variable fuel surcharges are applied alongside established rate structures.

Margins in road transport are often thin. A large and sustained increase in fuel costs may force operators to reconsider routes, pricing structures and investment decisions.

Those servicing regional and remote areas would be particularly affected. Longer distances mean higher fuel usage, which amplifies the impact of any increase in fuel tax. This has implications not only for operators but also for the communities that depend on these freight services.

Flow On Effects for Consumers

Freight costs do not remain within the transport sector. They flow through the entire economy.

When the cost of moving goods rises, we can be sure those costs are eventually reflected in the prices paid by us as the ultimate consumers. This is particularly noticeable in a country like Australia where long distances and dispersed populations already make logistics expensive.

Higher diesel costs would add pressure to supply chains that are already dealing with volatility and rising input costs. The result would likely be increased prices for everyday goods and, at a time when cost of living pressures are front of mind for many households, any policy that adds to the cost base of essential services is likely to attract significant scrutiny.

The Environmental Question

Supporters of reform argue that tax settings should support the transition to lower emission transport. There is logic in ensuring that environmental costs are reflected in pricing.

However, the trucking industry’s position is that taxation alone will not deliver this transition. Without significant investment in infrastructure, technology and incentives for alternative vehicles, higher fuel taxes may simply impose costs without delivering environmental benefits.

The reality is that for many freight tasks there is currently no commercially viable alternative to diesel. Until that changes, operators have little choice but to absorb or pass on the additional cost.

Budget and Political Considerations

Fuel tax credits represent a significant amount of foregone revenue for the Federal Government each year. The Productivity Commission’s recommendation is partly driven by the desire to rationalise this expense and redirect funds to other priorities.

At the same time, any change to fuel taxation is politically sensitive. It intersects with concerns about inflation, business costs and regional equity. Policymakers will need to balance fiscal objectives with the practical realities facing the freight sector and the communities it serves.

The Final Word

The proposal to more than double the effective tax on truck fuel has sparked a debate that reaches far beyond the transport industry. It raises questions about how Australia balances environmental ambition, fiscal responsibility and economic practicality.

For freight operators, the recommendation represents a significant financial challenge at a time when the industry is already under pressure. For consumers, it carries the risk of higher prices for everyday goods. For policymakers, it highlights the complexity of reforming long standing tax arrangements in a way that achieves intended outcomes without unintended consequences – such as inflation, which the RBA has sought to address this week with its latest rise to the cash rate.

What happens next will depend on how government weighs these competing priorities. What is clear is that any change to fuel tax settings for heavy vehicles will have wide reaching implications across Australia’s supply chains and the broader economy.
