Australia is unusually dependent on imported fuel for a rich country. The vulnerability comes from three layers.<\/p>\n
First, import dependence.<\/p>\n
Australia imports roughly:<\/p>\n
70 to 80 percent of its refined petroleum products
\nalmost all of its jet fuel
\nmost of its diesel<\/p>\n
The country produces crude oil but exports most of it because it is not the type best suited for its remaining refineries. Then it imports refined fuel back from Asia.<\/p>\n
Second, shipping concentration.<\/p>\n
Most fuel comes from a handful of Asian refining hubs:<\/p>\n
Singapore
\nSouth Korea
\nJapan
\nChina<\/p>\n
Tankers travel through a few key sea lanes:<\/p>\n
Strait of Malacca
\nSouth China Sea
\nIndonesian archipelagic routes<\/p>\n
Those are some of the most strategically contested shipping corridors in the world. In a conflict involving China or a disruption in Southeast Asian shipping, Australia\u2019s supply lines could be affected quickly.<\/p>\n
Third, storage.<\/p>\n
Australia historically kept very small fuel reserves. The country relied on constant tanker deliveries rather than large stockpiles. For years it had far less than the International Energy Agency requirement of 90 days of reserves.<\/p>\n
Because of that problem Australia started buying strategic reserves stored in the United States around 2020. Since then it has been trying to expand domestic storage as well.<\/p>\n
The result is a system that works extremely well in peacetime. Fuel arrives cheaply from giant Asian refineries.<\/p>\n
But in wartime or a shipping crisis, the country could face shortages faster than most developed economies.<\/p>\n
This is why the Australian government now subsidizes its remaining refineries and fuel storage. The goal is not efficiency. It is resilience.<\/p>\n
Strategists often describe the tradeoff this way.<\/p>\n
Globalization made fuel cheaper.
\nBut it also turned supply chains into a strategic risk.<\/p>\n
Australia is one of the clearest examples of that tradeoff.<\/p>\n
Australia used to refine a lot of its own petroleum. Over the last twenty years most of those refineries shut down. The basic reason is that refining in Australia became more expensive than importing refined fuel from Asia.<\/p>\n
Three forces drove the shift.<\/p>\n
First, scale. Modern refineries work best when they are huge. Asia built massive facilities in places like Singapore, South Korea, China, and India. Those plants process several hundred thousand barrels a day. Australian refineries were much smaller. That meant higher costs per barrel.<\/p>\n
Second, labor and regulatory costs. Australia has high wages, strict environmental standards, and expensive construction. All of that makes operating a refinery costly. A refinery in South Korea or Singapore can run the same operation cheaper.<\/p>\n
Third, geography and trade. Australia sits next to the largest refining hub in the world. Singapore is one of the global centers of petroleum refining and trading. Shipping refined gasoline or diesel from Singapore to Australia is cheap. Often it is cheaper to import finished fuel than refine crude locally.<\/p>\n
Because of those pressures, several refineries closed.<\/p>\n
Examples:<\/p>\n
Kurnell refinery in Sydney closed in 2014<\/p>\n
Bulwer Island in Brisbane closed in 2015<\/p>\n
Altona in Melbourne stopped refining in 2021<\/p>\n
Kwinana in Western Australia stopped refining in 2021<\/p>\n
Today Australia still has two operating refineries:<\/p>\n
Lytton in Brisbane<\/p>\n
Geelong in Victoria<\/p>\n
They survive partly because the Australian government subsidizes them to maintain some domestic capacity for national security.<\/p>\n
That leads to the strategic concern. Australia now imports about 80 to 90 percent of its refined fuel. Most comes from Asian refineries. In a major war or shipping disruption, that dependence could become a vulnerability.<\/p>\n
So the short answer is simple. Australia can refine oil. It just became cheaper to let other countries do it.<\/p>\n
Not massively cheaper per liter. The difference is small on each barrel. But the scale advantage makes the economics decisive.<\/p>\n
Typical numbers look like this.<\/p>\n
Refining costs themselves are often only about $2 to $3 per barrel for efficient refineries.<\/p>\n
But the margin refiners earn for turning crude into fuel varies widely. In Asia the benchmark refining margin is often $7 to $15 per barrel, and in tight markets it can spike to around $30 per barrel.<\/p>\n
So the cost difference between an efficient Asian refinery and a smaller high-cost refinery can be on the order of $1 to $5 per barrel, sometimes more depending on labor, environmental compliance, and scale.<\/p>\n
That may sound trivial. But do the math.<\/p>\n
A refinery processing
\n100,000 barrels per day<\/p>\n
If costs are even $3 per barrel higher, that is<\/p>\n
300,000 dollars per day
\nabout $110 million per year<\/p>\n
That gap alone can wipe out profits.<\/p>\n
The structural advantages Asian refineries have:<\/p>\n
Size
\nSome Asian refineries process 600,000 to over 1 million barrels per day, while the biggest Australian refinery was around 146,000 barrels per day.<\/p>\n
Integration
\nAsian plants are often integrated with petrochemical complexes, spreading costs across more products.<\/p>\n
Labor and regulatory costs
\nLower wages and less expensive environmental compliance.<\/p>\n
Regional hub
\nSingapore acts as the pricing hub for fuel in the region, and Australian wholesale fuel prices are tied to that benchmark.<\/p>\n
So the key point is this.<\/p>\n
The cost difference per barrel is modest.
\nBut because refineries operate on razor-thin margins and massive volumes, even a few dollars difference makes domestic refining uncompetitive.<\/p>\n
That is why Australia shut most of its refineries even though the country obviously has the capability to refine oil.<\/p>\n","protected":false},"excerpt":{"rendered":"
