Russian-Australian man charged over alleged operation to gather Ukrainian military secrets

Australian police have charged a 27-year-old Russian-Australian man with foreign interference after alleging he joined Ukraine's armed forces to obtain military information for Russian intelligence, the ABC reported.

Russia has repeatedly sought to obtain information about Ukraine's military through espionage and intelligence operations as it continues its full-scale invasion. The alleged operation also shows how Moscow can use individuals in third countries to gain access to Ukrainian military information and attempt to pass it to Russian intelligence.

The Australian Federal Police (AFP) arrested Vladimir Teslov on 20 August in Sumner, a suburb of Brisbane. He appeared in Brisbane Magistrates Court on 21 August, where his case was adjourned until 2 October, according to the ABC.

Alleged operation inside Ukraine

According to the AFP, Teslov traveled to Russia in October 2024 and underwent military-style training before returning to Australia in December.

Teslov allegedly maintained contact after his return with individuals he believed were connected to Russian intelligence services, the AFP said in a press release.

Police allege he traveled to Ukraine in May 2025 and joined the Ukrainian Armed Forces, where he gained access to information about Ukrainian military personnel, units, and locations.

The AFP alleges Teslov subsequently provided, or attempted to provide, information obtained in Ukraine to people he believed were acting on behalf of Russian intelligence.

The agency said he sought to collect and communicate information about Ukrainian military personnel, locations, and operations for the benefit of Russia.

AFP Commissioner Krissy Barrett said the alleged activity could have endangered Ukrainian troops.

“It is alleged that this conduct created a risk to the safety and security of Ukrainian military personnel,” Barrett said, according to ABC.

The allegations have not been tested in court.

Australia has been a major supporter of Ukraine since Russia launched its full-scale invasion in February 2022, providing about A$1.8 billion in military, economic, and humanitarian assistance.

Investigation into alleged Russian intelligence links

The AFP said its Counter Foreign Interference Task Force began Operation Woodcreeper in June 2026, following an extensive investigation by Australia's domestic intelligence agency, ASIO.

Australian authorities carried out searches at five properties in Queensland on 20 and 21 August, according to the AFP press release. Police seized electronic devices and other items relevant to the investigation, which will undergo forensic examination.

The AFP said further arrests are possible.

Barrett said there was no indication that Teslov posed a threat to Australia itself, although investigators allege parts of the activity took place both in Australia and overseas.

The foreign interference charge carries a maximum penalty of 20 years in prison.

The Russian Embassy in Canberra told ABC it learned of the case through media reports and had not received an official notification from Australian authorities or Teslov. It said it was using available channels to establish the circumstances of the case.

Russian espionage cases in Australia

Australian authorities have previously warned of Russian intelligence activity in the country.

ABC noted a separate case involving Russian-born Australian citizens Kira and Igor Korolev, who were arrested in 2024 and accused of attempting to gather and send sensitive information to Russia. Their charges were upgraded to conspiracy to commit espionage in June.

In 2022, Australian Security Intelligence Organisation (ASIO) Director-General Mike Burgess said the agency had disrupted a “hive of spies” from an unnamed country seeking to recruit Australians and obtain sensitive information. Multiple media reports later identified Russia as the country involved, although ASIO has not publicly confirmed this.

Last month, the Australian Signals Directorate and nearly two dozen international partner agencies warned that Russian-linked hackers were targeting Australian defense, communications, energy, and financial sectors.
