CANBERRA, Australia— Australia has joined Britain and Bahrain in signing onto a U.S.-led maritime security mission to protect international shipping in the Strait of Hormuz amid tensions with Iran, the prime minister said Wednesday.
Australia will contribute troops, a surveillance plane and a frigate to protect the shipping lanes from Iran, Prime Minister Scott Morrison said.
The “modest, meaningful and time-limited” contribution was in Australia’s national and economic interests, he said. At least 15 percent of crude oil and up to 30 percent of refined oil destined for Australia transits through the Persian Gulf.
The British Defense Ministry announced this month that Royal Navy vessels will work alongside the U.S. Navy to escort vessels through the busy strait off Iran's coast, which has become a flashpoint for tensions between Tehran and the West.
The U.S. has been asking its allies to take part in a naval mission to protect shipping in the strait, though other European nations have expressed reservations.
This geostrategic significance came into fresh focus when Iran’s President Hassan Rouhani recently threatened to close the Strait of Hormuz following the Trump administration’s decision to leave the Iran nuclear deal.
Britain has been giving U.K.-flagged vessels a naval escort since Iran’s Revolutionary Guard seized a British oil tanker last month.
Morrison said the Australian warship will be redirected from an anti-piracy operation in the Middle East, while the troops will be based in the headquarters that are coordinating the U.S.-led maritime security mission.
Initially, Australia will be involved for at least six months, but Morrison said the mission could be extended.
