Trading data compiled from multiple shipping sources shows ExxonMobil, BP and Vitol are moving an unusually large volume of refined fuels from the United States to Australia in March. At least 200,000 metric tons of gasoline, diesel and jet fuel have been loaded or are scheduled to load from the U.S. Gulf Coast and U.S. West Coast for delivery to Australia by the end of the month.
Based on U.S. Energy Information Administration data, that quantity is the most fuel shipped from the United States to Australia for a single month in more than three decades. The surge in U.S. shipments is replacing lost and curtailed supplies from Asia after a series of export restrictions and production reductions across the region.
China and Thailand have imposed bans on fuel exports to protect domestic inventories, and refiners across Asia are cutting output as crude flows from the Middle East are sharply reduced due to Iran's blockade of the Strait of Hormuz. Those developments have left Australia, which typically sources the vast majority of its product imports from Asia, looking farther afield for barrels.
Shipping records show ExxonMobil has booked three vessels to carry up to 120,000 tonnes across the three fuel categories. BP has chartered a tanker to lift 40,000 tonnes of diesel, while Vitol is shipping a cargo of 40,000 tonnes of gasoline. Representatives for Vitol and ExxonMobil declined to comment; BP did not immediately respond to a request for comment.
Chartering costs for medium-range tankers on the U.S.-to-Australia route are substantial. Two shipbroking sources estimate the cost to hire a vessel able to carry roughly 40,000 tonnes of product from the United States to Australia is at least $6 million - equivalent to about $150 a tonne. Transit times are long for these voyages, typically 30 to 40 days, compared with 10 to 20 days for shipments originating in Asia.
These trade flows are notable not only for volume but for the parties involved. All three companies moving these cargos - ExxonMobil, BP and Vitol - operate retail fuel stations in Australia, linking global shipping decisions directly to national retail networks.
Australia's supply position
The surge in U.S. shipments underscores Australia’s exposure to disruptions originating in the Middle East. Government statistics cited in trade data show Australia holds stockpiles well below global norms and imported 84% of its petroleum product needs last year. Kpler shiptracking data indicates Australia imported around 35 million tonnes of refined fuels in 2025, more than 90% of which came from Asian suppliers.
Sparta Commodities' vice president of oil analytics, Neil Crosby, said arbitrage flows from farther afield will increase while Asia remains tight. "There will definitely be more need for these types of (arbitrage) flows," he said, and added that Houston barrels are currently the cheapest source of gasoline into Australia, followed by the Amsterdam-Rotterdam-Antwerp hub in northern Europe.
Data from Sparta Commodities on March 18 showed gasoline from Houston for May delivery to Australia is roughly $17 a barrel cheaper than gasoline from Singapore, illustrating the price incentives that are prompting longer, costlier voyages to replace nearby Asian supplies.
Regulatory and policy actions
The market response has coincided with government and regulator interventions. Australia's competition regulator has opened an investigation into allegations of anti-competitive conduct by major fuel suppliers, including Ampol, BP's Australian unit, Mobil Oil Australia and Viva Energy, in which Vitol is a major shareholder. Separately, the government announced last Friday it would release petrol and diesel from domestic reserves to help address supply-chain disruptions that have contributed to shortages in rural areas.
These developments occur against a backdrop of higher shipping costs and slower turnaround times for imported fuel, factors that complicate rapid replenishment and could influence distribution decisions by downstream retailers and wholesalers.
