Vladimir Teslov, a 27-year-old from Victoria, appeared via video link in a Brisbane court on Friday. He was arrested in August by the Counter Foreign Interference Taskforce.
Teslov is charged with attempting to engage in intentional foreign interference. According to the AFP, he travelled to Russia in October 2024 for military-style training before returning to Australia. In May 2025, he allegedly travelled to Ukraine and joined the Armed Forces of Ukraine.
AFP Commissioner Krissy Barrett previously said the case is the first time a person with links to Russia has been charged with attempting foreign interference since the laws were introduced in 2018.
In court, Teslov sat with his arms crossed and his head down. When magistrate Ross Mack asked if he had any questions, Teslov replied: "No, your honour."
The prosecution alleges Teslov intentionally collected information from Ukraine's armed forces believing he was acting on behalf of, or at the direction of, the Russian Federation, and that it would support Russian intelligence activities. The offences are alleged to have occurred in Victoria, Ukraine and Russia.
The AFP said Teslov's actions risked the safety and security of Ukrainian military personnel. The case continues.
