An Australian Army reservist could face 20 years in jail after allegedly fighting in Ukraine last year without authorisation.
Vincent Tran, 25, was arrested at a home in Felixstow, in Adelaide’s north-east on Thursday, where Australian Federal Police officers seized several electronic devices, including a mobile phone and laptop.
He has been charged with one count of foreign work restricted individual working for a Foreign Military Organisation or Government Body, which has a maximum penalty of 20 years’ imprisonment.
This is the first time the AFP has charged someone with this offence.
Police allege Tran travelled to Ukraine in May 2025 to serve as a drone operator for the Armed Forces of Ukraine in the war with Russia without authorisation.
He is believed to have returned to Australia in January.
Defence legislation regulates the work certain individuals can perform for a foreign military, government or company without authorisation.
AFP officers began investigating the man after receiving a referral from Defence alleging Tran had worked for a foreign military without authorisation.
