American tankers to Australia are replacing Middle Eastern fuel suppliers as geopolitical friction and supply competition reshape regional logistics. Australian refiners and logistics operators face higher transport costs and longer lead times. This reflects a structural shift: energy supply chains built on proximity are fragmenting under pressure from Middle East tensions, US export capacity swings, and Australia's aging refinery base. The result appears in fuel prices and margins for diesel-dependent industries—transport, mining, agriculture—where energy security is now a measurable cost.
