Australia’s Strategic Oil Reserves: A Tight Squeeze in Global Disruptions
The global energy landscape is a complex web, and recent geopolitical events, particularly the conflict in the Middle East and the resulting disruptions to key shipping lanes like the Strait of Hormuz, have cast a stark spotlight on national oil reserves. For Australia, this scrutiny has revealed a situation that, while deemed secure by the government in the short term, highlights a significant reliance on overseas supplies and a domestic reserve level that lags behind many developed nations.
The federal government has been vocal in assuring the public that Australia’s fuel supply remains robust. While acknowledging that several shipments were initially impacted by the escalating tensions, they have confirmed that these have been replaced and that additional shipments have been secured, bolstering immediate availability. However, this short-term reassurance doesn’t entirely alleviate concerns about the nation’s longer-term strategic preparedness.
The IEA Obligation and Australia’s Reality
As a signatory to the International Energy Agency (IEA), Australia is bound by a commitment to maintain a minimum of 90 days’ worth of fuel reserves. Unlike many other member nations that maintain substantial government-controlled strategic stockpiles, Australia’s approach relies on oil companies holding “minimum stock holding” requirements for emergency reserves.
At the close of last year, the figures for these industry-held reserves painted a less than ideal picture. Australia had approximately 38 days’ worth of gasoline, 32 days of diesel, and a mere 29 days of jet fuel. These figures fall considerably short of the IEA’s mandated 90-day benchmark and have remained relatively consistent even with the ongoing global instability.
Global Benchmarks: A Stark Contrast
When compared to other developed economies, Australia’s reserve levels appear significantly more modest.
- Japan: Stands as a prime example of robust preparedness, boasting a combined total of 254 days’ worth of oil in both government and private reserves.
- South Korea: Also demonstrates a strong strategic position, holding around 200 days’ worth of oil.
- United States: Possesses the largest strategic petroleum reserve in the Western world. Prior to recent global events, this reserve held approximately 415 million barrels, sufficient for about 125 days of consumption. While this figure represents a decrease from earlier in the decade, the US also benefits from an additional 439.3 million barrels held in commercial, private hands.
- China: While official figures are not publicly disclosed, estimates from energy analytics firms suggest China’s oil inventory could reach 1.13 billion barrels by the end of 2025, potentially covering over 100 days of its estimated daily imports.
- European Nations: Many European countries have stringent legal mandates for fuel reserves. Italy and Germany are required to hold at least 90 days’ worth of oil, while France reported holding 108 days in early March. The United Kingdom maintains a stockpile of approximately 68 million barrels, estimated to last around 52 days based on current usage figures, though other estimates suggest it could be closer to 90 days or more.
Not Alone, But Still Lagging
It’s important to note that Australia is not the only nation that found itself with less than 90 days of fuel at the onset of recent global disruptions. New Zealand, for instance, currently holds less than 50 days’ worth of reserves. Canada, as a net exporter of oil, is not mandated by the IEA to hold a strategic reserve, making it the only G7 member without one.
However, according to official IEA data from late 2025, Australia held the smallest oil reserves among all IEA members and was the only nation with less than 80 days’ worth of imports on hand. This has been a persistent issue, with the country failing to meet the 90-day obligation for over a decade.
The Cost Factor: A Government Justification
Energy Minister Chris Bowen has consistently explained the government’s stance on not meeting the IEA’s 90-day obligation by citing the substantial financial cost. He has argued that accumulating such a reserve within Australia would incur an estimated $20 billion over four years, a significant expenditure that could otherwise be allocated to essential public services like schools and hospitals.
“Ninety days is not how much petrol is used,” Bowen stated in a recent podcast interview. “It’s a 90-day import days, and they can be held anywhere and it’s not for domestic supply. It’s to be able to sell it if things get rough and the IEA asks us to.” He reiterated that this is a significant financial commitment that successive governments have found difficult to justify.
Despite the current reserve levels, the government maintains that Australia is better positioned now than it was prior to previous global energy shocks. “We’ve got those 38 days of petrol, 30 days of diesel, 30 days of jet fuel and, you know, sure, people can say we need more, but it’s a lot more than we’ve had previously,” Bowen remarked.
Expert Concerns: Vulnerability in the Supply Chain
However, some industry experts and academics express concerns about Australia’s reliance on imported refined petroleum. Professor Sajid Anwar from the University of the Sunshine Coast highlighted that Australia’s exposure to global disruptions stems from its significant import of refined fuels.
“The country typically holds around 30 days of fuel stocks, well below the 90-day level recommended by the International Energy Agency,” Professor Anwar stated. He further pointed out that while Australia sources fuel from various suppliers in the Asia-Pacific region, such as Singapore, South Korea, and Japan, these sources are part of the same interconnected supply chain. Consequently, major regional disruptions could still have a considerable impact on Australia’s fuel availability. This intricate global dependency underscores the ongoing debate about the adequacy of Australia’s strategic oil reserves.
