The Australia biofuel market size reached USD 3.1 Billion in 2025. Looking forward, the market is expected to reach USD 9.5 Billion by 2034, exhibiting a growth rate (CAGR) of 12.40% during 2026-2034. The market is driven by government policies promoting renewable energy, rising environmental concerns, demand for cleaner fuels in transportation, advancements in biofuel technology, and increased investment in sustainable agricultural practices. Australia imports 100% of its jet fuel, consumes approximately 33.5 billion litres of diesel annually, and is strategically vulnerable to global energy supply disruptions — creating powerful national energy security incentives to accelerate domestic biofuel production capacity across ethanol, biodiesel, and sustainable aviation fuel segments. The Australian Government has announced AUD 1.1 billion in investment in low-carbon liquid fuels including ethanol and SAF, while ARENA has provided AUD 33.5 million across five SAF projects under its Sustainable Aviation Fuels Funding Initiative since 2023 — supporting innovation, commercialization, and pilot and demonstration projects targeting domestic SAF production capability. CSIRO's 2023 SAF Roadmap identified sufficient Australian feedstock to supply approximately 5 billion litres of SAF production — covering approximately 50% of forecast Australian jet fuel demand — positioning the country as genuinely capable of building a commercially significant domestic SAF industry by the early 2030s. State-level blending mandates in New South Wales and Queensland provide guaranteed markets for ethanol and biodiesel, forming the commercial foundation on which domestic biorefinery investment is being structured. The ethanol segment currently leads the market and is projected to reach USD 3.6 Billion by 2034 at a CAGR of 5.94%, while sustainable aviation fuel is the fastest-growing biofuel category, driven by airline net-zero commitments and the progressive establishment of supply chain and storage infrastructure at Australian airports. Queensland anchors the dominant regional position as Australia's primary sugarcane and biomass feedstock state, while New South Wales, Western Australia, and Victoria are all advancing biofuel infrastructure investment and blending program expansion.

How AI is Reshaping the Future of the Australia Biofuel Market

• AI technologies are enabling optimization in biofuel production processes across Australian biorefineries — reducing costs associated with feedstock processing, improving fermentation and transesterification efficiency, and addressing the high production cost challenges that have historically constrained the commercial competitiveness of domestic ethanol and biodiesel relative to imported fossil fuel alternatives.

• Through big data analytics and machine learning, AI is supporting supply chain optimization in the Australian biofuel sector by forecasting feedstock availability from sugarcane, canola, sorghum, and organic waste streams — helping biorefinery operators mitigate supply consistency challenges, reduce raw material price volatility exposure, and align production schedules with seasonal agricultural output patterns.
