Australia will join an international mission to ensure shipping from the Middle East continues as world leaders cautiously welcome the reopening of the Strait of Hormuz.
Anthony Albanese on Saturday acknowledged re-entry to the vital waterway was a "fragile arrangement" following an overnight summit of about 50 countries to support an ongoing ceasefire in the region.
The prime minister called for a full reopening "for all countries permanently" to ensure shipping resumes under the banner of the Strait of Hormuz Maritime Freedom of Navigation Initiative following the US-Israeli war with Iran.
