Prime Minister Scott Morrison said Wednesday that Australia will contribute troops, a surveillance plane and a Navy frigate to protect shipping lanes off the coast of Iran. He says it’s a “modest, meaningful and time-limited” contribution in Australia’s national and economic interests. At least 15 percent of crude oil and up to 30 percent of refined oil destined for Australia transits through the Arabian Gulf. The warship will be redirected from an anti-piracy operation in the Middle East, while the Australian troops will be based in the headquarters that are coordinating the US-led maritime security mission. Initially, Australia will be involved for at least six months.
