From Dubai: When oil prices doubled in a matter of days and global shipping ground to a halt, Australia suddenly confronted a reality it had treated as manageable: its exposure to Middle Eastern volatility. The regional dynamics at play are more complex than the headlines suggest, yet what Western coverage frequently misses is how thoroughly this conflict has shattered the illusion of a stable, defensible Gulf region.
On February 28, 2026, the United States and Israel launched coordinated airstrikes across Iran that killed Supreme Leader Ali Khamenei, effectively decapitating the country's leadership structure. Tehran's response was swift and comprehensive. For the first time in history, Iran attacked all six Gulf Cooperation Council states: Bahrain, Kuwait, Oman, Qatar, Saudi Arabia, and the United Arab Emirates. The conflict is no longer bilateral between Iran and Israel; it has become a regional conflagration with consequences that ripple directly into Australian shopping centres and petrol stations.
The immediate flashpoint was the Strait of Hormuz, that 30-mile-wide chokepoint through which roughly 20 per cent of the world's daily oil transits. When Iranian forces declared the strait "closed" on March 4 and began attacking commercial shipping, tanker traffic collapsed by 70 per cent. Ship after ship, including Greek oil tankers and Thai cargo vessels, were struck by Iranian missiles and drones. As of mid-March, the strait had become impassable for most commercial traffic, and oil prices surged from around $70 per barrel to over $110. The International Energy Agency released a record 400 million barrels of crude oil in an emergency measure.
For Australia, this signals a structural energy problem. The nation holds only 36 days of petrol reserves—significantly below the International Energy Agency's recommended 90-day buffer. Australia exports vast quantities of energy globally but remains dependent on imported liquid fuels. The Australian government, having ruled out participation in the U.S. and Israeli strikes, has nevertheless deployed surveillance aircraft and air-to-air missiles to the Gulf region to defend allied nations. Yet the underlying vulnerability remains: Australia's energy security rests partly on the stability of a region that has just demonstrated its fundamental fragility.
What the regional commentary frequently ignores is the logic driving Iran's response. The U.S. and Israeli objectives were explicit: regime change in Tehran and destruction of Iran's nuclear and ballistic missile capabilities. For Iranian policymakers, a measured response was impossible. Tehran faced a choice between capitulating to external pressure or striking back. The result has been asymmetric warfare at scale: dispersed attacks, drone swarms, missile barrages, and naval disruption that no regional air defence system was fully equipped to handle.
The human toll reflects this asymmetry. More than 2,000 people are dead across Iran, Lebanon, and Israel. Hundreds of thousands have been displaced, particularly in Lebanon. Hundreds of thousands of travellers remain stranded across the Middle East as commercial aviation grinds to a halt. The UN World Food Programme has warned that the disruption of fertiliser exports from the Gulf threatens global food security—roughly half of all food depends on synthetic nitrogen fertiliser, most of which transits the Strait on a just-in-time supply chain with no strategic stockpile.
For Australia's energy sector, this signals something more sobering than a temporary price spike: it reveals the limits of existing deterrence architecture and the speed at which a regional conflict can become an economic crisis. Whether the Strait reopens in days or weeks, the damage to assumptions about energy market stability has been profound. Australia's government has warned against panic buying of petrol, but the real warning is structural: when one man's death in Tehran can disrupt 20 per cent of global oil supply within hours, energy security is not something to manage at the margins.
The diplomatic off-ramps being quietly explored in various Gulf capitals may cool the immediate crisis. But the conflict has exposed truths about the region that no amount of diplomatic messaging can obscure: the Gulf's defensive capacity, despite billions in military spending, remains vulnerable to asymmetric attack; regional conflicts cannot be cordoned off from global markets; and Australia's energy independence remains an unfulfilled aspiration, not a settled fact.
