Understanding the Iran conflict
Who are the key players? What is the Strait of Hormuz? Why does Australia care? Everything you need to make sense of the daily news.
Who is involved and what do they want?
The conflict involves a web of state and non-state actors with overlapping and often conflicting interests. Here are the main players you'll see referenced in daily coverage.
Why the Strait of Hormuz changes everything
The Persian Gulf is one of the most strategically important bodies of water on Earth. At its mouth sits the Strait of Hormuz — a narrow channel just 33 kilometres wide at its narrowest point, bordered by Iran to the north and Oman and the UAE to the south.
Approximately 20% of the world's oil supply passes through the Strait of Hormuz every day, along with significant quantities of liquefied natural gas (LNG). There is no viable alternative route — tankers carrying Gulf oil to Asia, Europe, and the Americas must pass through it.
This geography gives Iran enormous leverage. Any Iranian action to disrupt, mine, or close the strait — even partially — would immediately spike global oil prices and send shockwaves through every economy on earth, including Australia's.
The Red Sea is a secondary chokepoint. Yemen's Houthi rebels, backed by Iran, have been attacking commercial ships there since late 2023. Many shipping companies have rerouted around the Cape of Good Hope, adding weeks and thousands of dollars to each voyage — costs that flow through to consumers globally.
Australia sits on the other side of the Indian Ocean from the Persian Gulf. Almost all oil imported by Australia's Asian trading partners — Japan, South Korea, China — transits the Strait of Hormuz. Any disruption affects demand for Australian LNG as a substitute or complement.
Australian naval vessels periodically operate in the region as part of multinational coalitions protecting shipping. The RAAF has conducted surveillance missions over the Middle East. Australia has both an alliance commitment (ANZUS) and a direct economic stake in regional stability.
How we got here
The current crisis has roots going back decades. Here are the key moments that shaped the situation today.
Why this matters to Australians specifically
Australia is geographically distant from the Middle East but deeply connected to it through alliances, energy markets, and trade relationships.
Energy prices. Australia imports most of its liquid fuel. When Persian Gulf tensions spike oil prices globally, Australians pay more at the petrol bowser and for everything that gets transported by truck or ship — which is nearly everything.
LNG exports. Australia is one of the world's largest LNG exporters. When Middle Eastern supply is threatened, Asian buyers look to Australia as an alternative. This can push Australian domestic gas prices higher but also boosts export revenue. It's a double-edged sword.
Alliance obligations. Australia is a formal US ally under ANZUS. When the US deploys forces to the Persian Gulf region, Australia is often asked to contribute — with ships, aircraft, or intelligence assets. Australian governments must navigate between alliance loyalty and independent foreign policy.
Trade routes. A significant portion of Australian exports to Europe and the Middle East pass through or near the conflict zone. Red Sea disruption adds costs and delays to Australian shipping.
Iranian-Australian community. Australia has a substantial Iranian diaspora, particularly in Melbourne and Sydney. Many have family in Iran and are personally affected by the conflict, sanctions, and any potential escalation.
Government position. Australia has consistently supported a diplomatic solution to Iran's nuclear programme, backed international sanctions, and maintained the Iran-Saudi Arabia diplomatic normalisation. Australia designates Hezbollah as a terrorist organisation.
