Australia Fuel Security Risk Assessment

Australia imports approximately 90% of its liquid fuel requirements, with a significant share of crude oil and refined products transiting the Strait of Hormuz. This creates a structural vulnerability that is rarely discussed at the community level but has direct implications for regional preparedness.

The Hormuz Dependency

The Strait of Hormuz is the world's most critical oil chokepoint — roughly 20% of global petroleum liquids pass through it daily. For Australia, the dependency pathway looks like this:

Crude oil from Middle East producers (Saudi Arabia, UAE, Iraq) transits Hormuz en route to Asian refineries
Refined products (diesel, petrol, jet fuel) from Singapore and South Korea — processing Gulf crude — are shipped to Australian ports
Australia's domestic refining capacity is now minimal (two refineries remain: Ampol Lytton QLD, Viva Energy Geelong VIC)

A Hormuz closure or sustained disruption would tighten global refined product supply within days and reach Australian bowsers within 2–4 weeks.

Risk Scenario Table

| Risk Event | Probability (12 months) | Lead Time to Impact | Severity | |------------|------------------------|---------------------|----------| | Iran-Israel escalation near Hormuz | Medium | 2–4 weeks | High | | Houthi Red Sea disruption (sustained) | High (ongoing) | 1–3 weeks | Medium–High | | Singapore refinery outage | Low–Medium | 1–2 weeks | Medium | | Domestic port industrial action | Low–Medium | Days | Medium | | Cyclone disruption (QLD/NT ports) | Medium (seasonal) | Days–1 week | Medium | | Multi-event coincidence | Low | 2–4 weeks | Extreme |

Australia's Strategic Reserve Position

Australia's International Energy Agency (IEA) commitment requires 90 days of net import cover. In practice, Australia holds:

~28 days of total liquid fuel stocks (industry + government combined)
Significantly below the IEA target
No dedicated strategic petroleum reserve (unlike USA, Japan, Germany)

The 2021 agreement to store fuel in the US Strategic Petroleum Reserve is a partial mitigation but not a rapid-response solution for regional communities.

Northern Rivers Specific Exposure

The region's exposure is amplified by:

Distance from major fuel terminals (Brisbane, Port Botany)
Road network vulnerability (flooding, landslip on Pacific Highway)
High diesel dependency (agriculture, transport, generators, fishing)
Limited local storage infrastructure

Monitoring Approach

The MRN Intelligence Dashboard tracks leading indicators including tanker movements through Hormuz and into Australian ports, wholesale fuel price differentials, and AIP retail/rack price data — providing an early-warning layer for community and local government planning.
