According to WPB, Australia’s decision to fund an early-stage study into a new large-scale oil refinery marks a significant change in the country’s fuel-security policy and could eventually have consequences beyond petrol and diesel. The proposed Western Australian project, if it proceeds, would be the country’s first new major refinery in about six decades and its third large-scale operating refinery. The immediate objective is to strengthen domestic fuel resilience, but the project could also affect the future structure of Australia’s bitumen supply, provided the final design includes the units, crude slate and residue-management strategy required to produce paving-grade material.
The federal and Western Australian governments are set to provide A$4 million for an initial feasibility study into a refinery proposed by Perdaman. The project remains at a very early stage. No final investment decision, processing capacity, construction timetable or product configuration has been confirmed, and a modern refinery would require several billion dollars of capital. The study does, however, show that refining capacity has returned to the centre of national energy planning after years of growing dependence on imported petroleum products.
Australia currently operates only two major refineries: Ampol’s Lytton facility in Brisbane and Viva Energy’s plant in Geelong. Together, they produced about 12 billion litres of petrol, diesel and jet fuel in 2025, equivalent to roughly one-fifth of national annual requirements. Australia now imports around 90% of its liquid fuels, leaving the domestic market closely connected to refining centres and shipping routes across Asia.
The policy shift follows a period in which global disruptions tested Australia’s supply system. The government has already announced a fuel-security program that includes a A$7.5 billion facility to support additional fuel and fertiliser supply and storage, together with a A$3.2 billion government-controlled reserve intended to hold around one billion litres of diesel and jet fuel. It would form part of a broader system combining domestic processing, strategic storage, emergency procurement and continued regional trade.
For the bitumen sector, the most important point is that a new oil refinery does not automatically become a new bitumen producer. Bitumen output depends on refinery configuration, crude quality, vacuum distillation capacity, product specifications and the treatment of heavy residue. A highly complex refinery may direct vacuum residue into conversion units to maximise transport-fuel production rather than sell it as paving binder. A refinery designed with suitable residue handling and a clear bitumen strategy could, by contrast, provide a new domestic source. Until technical details are released, any estimate of future bitumen output would be premature.
The potential relevance is nevertheless substantial because Australia’s existing domestic bitumen base is concentrated. The Geelong refinery is currently the country’s only local bitumen producer and has been estimated to provide about one-fifth of national supply, with the balance supported mainly through imports. Recent disruption at that facility and wider maritime supply problems demonstrated that a narrow production base matters for road authorities, asphalt producers, spray-sealing contractors and distributors.
That outcome would not necessarily reduce the role of international traders. Australia’s geography, seasonal road programs, state-level demand differences and distance from major refining hubs mean imported cargoes are likely to remain essential even if a new refinery is built. The more probable result would be a mixed supply system in which additional domestic output complements imports, strengthens regional inventories and gives buyers more sourcing options. Traders with reliable shipping, storage and technical capabilities could continue to play a central role, particularly during maintenance periods, demand peaks or grade mismatches.
The location in Western Australia could be commercially significant. A refinery in the west would sit closer to Indian Ocean trade routes and to supply relationships linking Australia with Singapore, Malaysia, South Korea, the Middle East and other Asian refining centres. On the same date that the refinery study emerged, Australia and Singapore signed a protocol to strengthen cooperation on energy security, essential supplies and trade. These developments indicate that Australia is not turning away from regional commerce. Its emerging strategy appears to combine stronger domestic capability with deeper supply-chain cooperation.
For bitumen suppliers, this combination could create opportunities rather than close the market. A western refinery could support new storage, blending, testing and distribution infrastructure, while imported material could continue to fill regional and seasonal gaps. International suppliers able to meet Australian specifications and provide dependable delivery would remain relevant in a market that values resilience as well as price.
A new refinery could also influence the type of bitumen demanded. Australia’s road network uses paving binder across asphalt production, sprayed seals, maintenance and rehabilitation. Future demand is likely to place increasing emphasis on consistent quality, polymer modification, performance in extreme climates and technical support. If a new refinery enters the market, its competitiveness would depend not only on volume but also on its ability to produce grades suited to local standards and regional conditions.
There are also major economic questions. Australian refining has historically faced competition from large Asian plants with scale advantages and lower unit costs. A new facility may require government support, concessional finance or long-term policy certainty to remain viable. Its business case would need to account for changing fuel demand, vehicle electrification, emissions policy, crude availability and Australia’s high construction costs. Including bitumen and other specialised products could improve diversification, but it would not guarantee commercial success.
Environmental policy will also shape the proposal. Australia is expanding renewable energy, low-carbon liquid fuels and transport electrification while seeking protection against near-term oil-supply shocks. Any new refinery would need to demonstrate how it fits within long-term emissions objectives. The final project may therefore differ substantially from a conventional refinery built decades ago.
For the wider Asia-Pacific bitumen market, the proposal introduces a new strategic possibility. Australia has traditionally been an important destination for imported petroleum products and paving binder. A new refinery with bitumen capacity could modestly rebalance regional flows, particularly into Western Australia, but it would be unlikely to eliminate national import demand. Instead, it could create a more distributed system in which domestic production, Asian supply hubs and specialist traders operate together.
The immediate market impact will be limited because the project has not advanced beyond feasibility work. Construction, approvals, financing and commissioning would take years even under a favourable scenario. The present significance lies in the policy direction. Australia is reassessing the value of domestic refining after a period of supply stress, while also strengthening storage and international partnerships. For the bitumen industry, the central question is whether the proposed refinery will be designed only around transport fuels or whether paving-grade bitumen will be included as a strategic product.
If bitumen capacity forms part of the final plan, Australia could gain a second domestic source, improved geographic balance and greater flexibility during international disruptions. If it does not, the study will still matter because it confirms that refinery configuration, residue economics and supply security are returning to national policy discussions. Producers, traders and contractors should therefore view the proposal not as an immediate change in supply, but as an early indicator of how Australia may organise its petroleum and bitumen market over the next decade.
