The AFP began an investigation after receiving a referral from Defence alleging the South Australian man, 25, a member of the ADF Reserves, had worked for a foreign military without authorisation.
Defence legislation regulates the work certain individuals can perform for a foreign military, government or company without authorisation.
It is alleged the Felixstow man 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. In January 2026, he returned to Australia.
AFP investigators executed a search warrant at a home in Flexistow on Thursday (2 April, 2026) and seized several electronic devices, including a mobile phone and laptop. Forensic examination of the electronic devices allegedly identified images linking the man to participation in a foreign conflict.
The electric devices will be subject to further AFP forensic analysis.
The man was charged with one count of foreign work restricted individual working for a Foreign Military Organisation or Government Body, contrary to section 115A of the Defence Act 1903 (Cth).
The maximum penalty for this offence is 20 years' imprisonment.
AFP Counter Terrorism Commander Paula Hudson said the AFP worked closely with its local, Commonwealth and international partners to protect Australia's interests.
Anyone with information about individuals with sensitive Defence knowledge intending to work for a foreign military or government body, or who have done so without authorisation, should contact the National Security Hotline (1800 123 400).
