Australian diesel imports through July 2026 ran 4.6% higher than during the same period in 2025, according to data published in the Crude Oil Peak analysis of Australian Petroleum Statistics. The increase occurred despite reduced flows through the Strait of Hormuz and general supply constraints affecting Asian refineries.
Customs data shows that import volumes varied significantly by country of origin. South Korea remained the leading supplier by volume, followed by Singapore and Taiwan. Malaysia, Brunei, and the United States or United Kingdom accounted for 9% each, while Japan and India each held a 5% share. China represented a very low share of total Australian diesel imports during the tracking period.
However, analysts indicate that market conditions shifted notably after July following the collapse of a key Memorandum of Understanding. Additional pressures have emerged around onshore stock levels, with reports highlighting potential vulnerabilities as domestic reserves approach mandatory stockholding obligation thresholds.
