Sydney man jailed for 3.5 years over fake defence reports prepared for Chinese spies

Alexander Csergo, a Sydney man, was sentenced to three years and six months in prison for producing fabricated defence reports to assist Chinese intelligence agents. Although the reports were deemed worthless by authorities, the case highlights concerns over covert foreign influence and the need to deter others from engaging in activities that threaten Australia’s national security.

A Sydney man was sentenced to three years and six months in prison on Thursday for preparing fabricated defence reports intended for Chinese intelligence operatives. Alexander Csergo, 58, was found guilty in March of knowingly assisting agents believed to be working for China’s Ministry of State Security.

The New South Wales District Court heard that between May and December 2022, Csergo produced a series of plagiarized and misleading reports concerning Australia’s defence arrangements and other sensitive topics. These included details about Australia’s involvement in the Quad security group and the Aukus alliance. The reports, compiled from open-source material, also covered areas such as lithium mining, German politics, and security issues.

Csergo’s interaction with the Chinese agents—identified only as Ken and Evelyn—originated from a LinkedIn message in November 2021, when a woman claiming to represent a Chinese thinktank contacted him. At the time, Csergo was residing and working in China as an IT consultant. The court was told he should have been aware that his contacts were intelligence operatives, but Judge Craig Smith ruled there was insufficient evidence to prove that Csergo was immediately reckless about offering assistance.

“Spotting Chinese intelligence operatives on that program requires training on what to look for,” Judge Smith remarked, noting that Csergo’s lack of experience made it difficult to determine his state of mind at the outset of the relationship.

Throughout the period in question, Csergo handed over the reports in person during private meetings at restaurants and cafes. In exchange, he received envelopes containing thousands of dollars in cash. The defendant also falsely claimed to have interviewed high-profile figures, including former Australian Prime Minister Kevin Rudd.

While the information provided by Csergo was ultimately deemed worthless by the authorities, the jury accepted that his collaboration held value for the Chinese operatives. Judge Smith described the operation as lacking in sophistication, though acknowledging the extensive nature of Csergo’s activities.

After returning to Australia in early 2023, Ken gave Csergo a list of sensitive subjects to research, but the judge found no evidence that Csergo engaged in espionage related to those requests.

In sentencing, Judge Smith emphasized the importance of deterring others in the community from becoming involved in activities that could undermine Australia’s national security. With time already served taken into account, Csergo will be eligible for parole in October.
