Australia exported more than 60 million litres of locally produced biofuels in the first six months of 2026, even as domestic fuel supplies faced pressure, prompting renewed calls for major fuel importers and refiners to buy more Australian-made alternatives.

The figures, reported by the ABC on 20 October, have sharpened debate about the country’s reliance on imported fuels and the role domestic ethanol and biodiesel could play in supply security.

A newly formed Biofuel Producers Alliance wants mandatory domestic purchasing arrangements. The federal government is considering policy options, but a binding national requirement to buy the fuels has not yet taken effect.

What Australia is exporting

Biofuels can be produced from agricultural products and by-products, including sugarcane, wheat-derived materials, used cooking oils and other feedstocks.

The Biofuel Producers Alliance brings together Manildra Group, Wilmar Sugar and several biodiesel companies. According to the ABC, members have around 470 megalitres of ethanol and biodiesel production capacity, equivalent to roughly three days of additional national fuel supply under the alliance’s estimate.

A megalitre is one million litres. More than 60 megalitres exported in the first half of the year therefore means more than 60 million litres of locally produced fuel products sold overseas.

That amount should not be confused with the group’s total annual production capacity, nor should the estimated three days of supply be portrayed as a national stockpile already sitting ready at service stations. Capacity, actual production, exports and fuel held in usable inventory are different measurements.

The alliance argues that Australian-made fuel is being exported because there is insufficient domestic demand from major importers and refiners. It wants public policy to create that demand.

Why the timing matters

Australia has faced price and supply pressures amid international uncertainty affecting petroleum markets. The ABC reported an average petrol price of about $2.42 a litre and concern about supply as the summer holiday season approaches.

The report also noted that fuel stocks had improved from earlier in the year, with around 41 days of petrol supply and 33 days of diesel supply. Those numbers still differ significantly from international fuel-stockholding benchmarks.

It is important not to confuse a measure of national stockholding with a guarantee of fuel at every bowser. Distribution bottlenecks and regional demand can create local shortages even when aggregate stocks exist. Conversely, exporting domestic biofuel does not automatically prove that every shipment could have been redirected immediately into suitable Australian vehicles or fuel blends.

Fuel security is a network problem. Domestic production matters, but so do storage, refinery capacity, compatible fuel standards, transport logistics and the mix of vehicles using petrol, diesel or other energy sources.

The biofuel producers’ case

Biofuel Producers Alliance chief executive Matt Hobbs argued that using more Australian-made products could reduce reliance on international supply chains and support local agriculture.

The group says a blending or purchasing requirement would encourage suppliers to take fuel produced domestically rather than relying solely on products sourced from overseas. It also sees an opportunity for farmers and processors to benefit from stronger demand for by-products of agricultural production.

The argument has an appeal at a time when consumers are worried about fuel prices and energy security. But its economic effect depends on the structure of the mandate and how costs are passed through the supply chain.

A requirement to buy more domestic fuel could stimulate investment, yet customers and regulators would also need to understand its effects on blending costs, availability, vehicle compatibility and competition.

The industry estimates that greater use of domestic biofuel could help buffer price shocks. That is an industry claim about a possible future outcome, not a verified reduction in pump prices that has already occurred.

What the government is considering

The federal government is consulting on the potential introduction of a ‘volumetric mandate’ — a policy requiring specified quantities of eligible alternative liquid fuels to be supplied or acquired.

The ABC reported that a consultation proposal contemplated a requirement beginning in 2029. The producers’ alliance has pushed for earlier action, illustrating a disagreement about how quickly a scheme should operate.

The policy discussions also extend to low-carbon liquid fuels that may be particularly important for transport applications where electrification is difficult. Such fuels could have a role in aviation and some heavier transport uses, although their environmental benefits vary with production methods and feedstocks.

Consultation is not enactment. The eventual scheme, its timing, coverage, exemptions and enforcement will depend on government decisions following the process.

Benefits and trade-offs

There are at least three separate questions for policy makers. First, would a domestic requirement materially improve fuel security when global supply chains are disrupted? Second, would it deliver reasonable value to motorists and businesses? Third, would the production and use of eligible biofuels provide genuine environmental benefits over their lifecycle?

The answers are not necessarily identical. A fuel produced domestically may reduce some transport-related exposure to overseas supply, while its price and emissions profile still depend on feedstock, processing and blending.

A well-designed policy would need measurable objectives, transparent reporting and safeguards to prevent claims of benefit exceeding the actual results.

It would also need to recognise that domestic capacity does not expand overnight. Supply agreements, investments in production and distribution changes take time. The risk of rushed design is that costs could rise before anticipated benefits are realised.

Why a local fuel supply matters to drivers and freight operators

Fuel availability affects far more than the price shown on a service-station sign. Logistics firms, farmers and regional businesses depend on reliable supplies to move goods and keep equipment operating. When international shipping or refining disruptions tighten the market, import dependence can increase exposure to price swings. Domestic fuel production may diversify sources, but it cannot automatically replace every imported petrol or diesel product because fuels differ in formulation, volume and vehicle compatibility.

That distinction matters for drivers considering ethanol blends or businesses evaluating alternative diesel. A fuel is only useful if it meets relevant standards and is appropriate for the engine and distribution infrastructure involved. More local production could improve resilience in some parts of the market, but the consumer benefit would depend on purchasing contracts, costs, supply chains and how quickly producers can deliver suitable products.

How a purchasing mandate might affect prices

The Biofuel Producers Alliance is calling for a requirement that major fuel companies buy defined quantities of domestic alternatives. A mandate could offer producers more predictable demand, encouraging long-term investment. On the other hand, obligated buyers may face costs if required supplies are more expensive or distribution systems need changes. It is therefore not enough to say that local fuel must be cheaper simply because it avoids an overseas shipment.

The federal consultation discussed by the ABC envisages a volumetric approach beginning in 2029, while producers favour earlier action. That timetable is a proposal rather than enacted national purchasing law. The Australian Chamber of Commerce and Industry has urged caution about market obligations unless supply and infrastructure are ready. Assessing the proposal requires evidence about price, emissions, implementation and the ability to scale without disrupting consumers.

Farmers, investment and the low-carbon transition

Some biofuels are made from agricultural by-products and used oils, connecting the industry with grain, sugar and food-service supply chains. A stronger domestic market could alter the incentives for investment in regional processing. Yet each feedstock has its own economic and environmental implications, and expanding one type of fuel does not guarantee equal benefits across the farming sector. Claims about jobs, emissions savings or lower prices need product-specific evidence.

The Australian Institute of Petroleum has supported policies that encourage lower-carbon liquid fuels, particularly in sectors where electrification can be more difficult. Heavy freight, agriculture, mining and aviation have different technical requirements from passenger cars. This explains why policy discussions may increasingly target renewable diesel and sustainable aviation fuel as well as ethanol blending. It does not mean a proposal has already delivered the volumes or emissions reductions being forecast by industry advocates.

What would demonstrate success?

A useful policy evaluation would track fuel delivered to Australian users, its compliance with standards, pricing during disruptions and the impact on domestic producers. Ministers would also need to make clear whether the costs are carried by suppliers, consumers or public budgets. A purchasing obligation without transparent monitoring could encourage domestic output yet fail to improve affordability in the way advocates hope.

For now, the verified position is narrower than either side’s strongest promise. Millions of litres were exported while Australia faced fuel concerns, producers want an obligation to buy locally, and the government is consulting on options. Whether new rules will appear, when they would start and how much consumers would pay remain open questions. That is why fuel security, agricultural investment and household costs belong in the same debate, but not in a headline claiming savings already achieved.

What comes next?

The next stage is the government’s consideration of submissions on the proposed mandate. Fuel companies, agricultural producers, consumer advocates and environmental organisations may offer competing views about volumes, timetables and acceptable costs.

The central figures already make the issue worth debating: more than 60 million litres of biofuel exported in six months and a domestic industry arguing that local production could play a bigger role in Australia’s fuel security.

Those numbers show potential supply, not a completed policy solution. Whether Australian-produced fuel is used at home in greater volumes will depend on government choices, commercial contracts and the practical capacity of the fuel system.

For consumers, the question is what would improve reliability and affordability at the bowser without shifting hidden costs onto households. For the government, it is a test of whether domestic industry policy can deliver a measurable public benefit at a time of continued fuel-market pressure.
