Western Australia's Planned Oil Refinery Faces Economic Scrutiny and Subsidy Reliance

A A$4 million feasibility study for a new Western Australian oil refinery will, by expert consensus, conclude the project is uneconomic and structurally dependent on public subsidies. According to reporting by The Guardian, the Albanese government announced the early-stage study alongside the WA government for a Pilbara-based facility this week. The framing matters less as an energy decision than as a signal — one that lands precisely as Australia's domestic crude base enters what Geoscience Australia calls terminal decline.

The commercial arithmetic

Greg Bourne, a Climate Council councillor and former regional president of BP in Australia, treats the proposed refinery as a straightforward capital allocation problem. A refinery must clear a profitable return horizon of 20 to 30 years, he notes. That horizon now sits inside a contracting demand curve: renewables are scaling, oil and gas consumption is on track to fall, and by 2036 the underlying logic of refining capacity erodes further. Prof Frank Jotzo, director of the Centre for Climate and Energy Policy at ANU, extends the argument to competitive structure. Any new Australian facility would compete with mega-refineries in Singapore and South Asia — facilities with superior scale and lower unit costs. Without subsidy, the Australian plant does not clear the market.

The signal problem

Jotzo's sharper critique targets the policy signal rather than the balance sheet. Investment in a refinery reads, in his framing, as "a big signal against the clean energy transition." The implication is structural: every public dollar committed to a long-lived fossil asset forecloses capital deployment on the alternatives — renewable electricity, zero-emission liquid fuels, the kind of next-generation adsorption and storage technologies now emerging from research programs like the HULU framework recently published by teams at South China University of Technology and Xi'an Jiaotong University. As Jotzo puts it: "If you want to subsidise anything, then subsidise the next generation of technologies… rather than some dinosaur tech that could still be there in 50 years' time."

The structural backdrop

The timing is not incidental. Geoscience Australia's 2025 commodity resource report states that domestic crude production "continues to decline rapidly, and without new commercial discoveries, production is projected to cease within the next 7 years." Baethan Mullen, chief executive of the Superpower Institute, draws the implication: a new refinery would almost certainly refine imported crude, doing little for sovereign capability. His institute's analysis places Australia at 95 percent reliance on foreign fuel imports, with only 4 percent refined locally from Australian crude. A subsidy-backed refinery built to refine imports it does not control is, functionally, a nationalization of refining margin risk — a structural exposure the public would absorb regardless of who signs the construction contracts.

The feasibility study will proceed regardless. What it is unlikely to do is change the underlying physics: refineries are long-duration, capital-intensive assets whose value accrues over decades. In a market where the demand side is contracting on policy rails, the study's value lies less in its conclusion than in its timing — a window for the policy signal to be retracted before the subsidy commitment hardens.
