Australian police searched the home of a British former test pilot for documents related to China's J-16 strike fighter, Australia's intelligence partners, and China's biggest aviation company, a court judgment shows.
The search in November was part of an investigation into Western military pilots training China's military at a time of growing tension between China and the United States and its allies.
Britain and Australia have announced crackdowns on former military pilots working to train Chinese fliers, and Britain vowed to change its national security law to stop them working for intermediaries including a South African flying school, which was alleged to be helping China's People's Liberation Army (PLA) recruit pilots.
