Australia’s biggest defence export deal ever Story flow and key facts
Australia has secured its largest-ever defence export deal, finalizing a $2.5 billion agreement to sell its advanced over-the-horizon radar technology to Canada. The system, modeled on Australia’s decades-old Jindalee Operational Radar Network (JORN), will help Canada monitor vast stretches of the Arctic with surveillance coverage extending thousands of kilometers. This marks the first time Australia has exported this sensitive technology, reflecting a growing ambition in defence industry outreach under its current government. The deal was confirmed after Canadian Defence Procurement Secretary Stephen Fuhr announced the signing during a visit to Australia, highlighting a strategic shift in bilateral defence ties.
