An Australian Army reservist faces up to 20 years in prison after authorities charged him with serving in Ukraine’s military without approval.
Arrest and Charges
Vincent Tran, 25, underwent arrest at a residence in Flexistow, northeast Adelaide, on Thursday. Federal police officers confiscated multiple electronic items, including a mobile phone and laptop, during the operation.
Officials charged Tran with one count of a restricted individual engaging in work for a foreign military organization or government body. This marks the initial instance of such a charge by Australian Federal Police.
Alleged Activities in Ukraine
Investigators claim Tran traveled to Ukraine in May 2025 and operated drones for the Armed Forces of Ukraine amid the conflict with Russia. He reportedly remained overseas for eight months before returning to Australia in January.
Defence regulations prohibit certain personnel from undertaking roles with foreign militaries, governments, or firms absent proper authorization. The probe originated from a Defence referral highlighting Tran’s unauthorized involvement.
Forensic analysis of the seized devices uncovered images tying Tran to participation in a foreign conflict, with additional examinations ongoing.
Court Appearance and Official Statement
Tran appears in Adelaide Magistrates Court on Tuesday.
AFP Counter Terrorism Commander Paula Hudson stated that the agency collaborated closely with local, Commonwealth, and international partners to protect Australia’s interests. She encouraged anyone aware of individuals possessing sensitive Defence information who plan or have worked for foreign militaries or governments without permission to call the National Security Hotline at 1800 123 400.
