A District Court jury found Csergo guilty in March after hearing evidence about his communications with two people he knew as "Ken" and "Evelyn" between 2021 and 2023. The prosecution argued Csergo believed they worked for China's Ministry of State Security and was reckless as to whether his conduct would support foreign intelligence activities.
Judge Craig Smith found the offending effectively took place between May or June 2022 and December 2022. He said Csergo's subjective awareness shifted around May 2022 when he was asked to prepare a defence report "materially different" from his previous work. WeChat messages showed the men requested topics including "China spy" and "anything about China in ASIO".
Csergo warned Ken they needed to be "careful" and said "we don't want to find ourselves being questioned by any governments". The judge found there was "clearly a persistence in his conduct" as he "extensively researched, downloaded and prepared materials". He described a "degree of sophistication" but said it was not "overly sophisticated in the criminal sense".
The defence argued Csergo handed over worthless information from open-source material and fictitious interviews, and never revealed any national security secrets. The judge handed a backdated sentence of three years and six months with a non-parole period of one year and ten months, meaning Csergo becomes eligible for parole consideration on 24 October 2026.
