Australia & the Strait of Hormuz.
Australia's direct Hormuz exposure is moderate, but the indirect exposure is the more interesting story. With domestic refining largely gone, Australian fuel comes increasingly from Korean, Singaporean, and Malaysian refineries — whose feedstock is Hormuz crude. A closure therefore lands on Australian drivers through Asian refining margins, not through direct cargo flows. On gas, Australia is the world's largest LNG exporter and net-positive in any chokepoint scenario. The strategic-reserve story has historically been awkward for IEA compliance; the US ticket-storage arrangement closed the gap. RAN deployments to the Gulf of Oman under Operation Manitou give Australia a small but continuous presence in coalition operations.

Key facts
- Direct crude Hormuz exposure is moderate — roughly 24% of crude imports.
- The larger exposure is *refined* products from Korea, Singapore, and Malaysia, whose feedstock is Hormuz crude.
- Australia is the world's largest LNG exporter — net exposure on the gas side is positive (a producer) rather than negative.
- IEA-mandated 90-day stockpile has historically been below compliance; ticket-based arrangements with the US closed the gap.
- Refining capacity has shrunk to two domestic refineries; Australia is structurally an importer of refined products.
Vulnerabilities
- Refined-product import dependence translates Korean and Singaporean refining margins directly into Australian pump prices.
- Aviation fuel supply is uniquely thin: the country's defence operations and civil aviation share the same import streams.
- Strategic reserve has historically been smaller than peers; the US ticket-storage arrangement is a partial workaround.
Mitigations
- Domestic LNG production removes any direct gas-side Hormuz exposure.
- US-based ticket-storage arrangement provides effective reserve coverage.
- Diverse refined-product supplier mix (Korea, Singapore, Malaysia) reduces single-supplier risk.
- Long Royal Australian Navy presence in the Gulf of Oman through Operation Manitou.
Historical context
Australia's refining base contracted sharply through the 2010s, leaving the country structurally dependent on Korean, Singaporean, and Malaysian refineries that themselves run on Hormuz crude. The IEA reserve compliance gap was a persistent policy issue until the US ticket-storage agreement in 2020.
