Australia’s top intelligence official has warned that state-backed Chinese hackers have been probing the country’s telecommunications systems and critical infrastructure, heightening fears of potential cyber sabotage that could disrupt essential services and economic stability.
Speaking at a business conference in Melbourne, Mike Burgess, Director-General of the Australian Security Intelligence Organisation (ASIO), said espionage and cyber intrusions cost Australia an estimated A$12.5 billion (US$8.1 billion) last year — including A$2 billion in stolen trade secrets and intellectual property.
Chinese State-Linked Groups Under Scrutiny
Burgess identified two prominent threat actors, Salt Typhoon and Volt Typhoon, as hackers “working for Chinese government intelligence and the military.” He said both groups have engaged in long-term espionage targeting U.S. and Australian networks, focusing on telecom, energy, and logistics infrastructure.
While Volt Typhoon is believed to have the capability to disrupt U.S. critical infrastructure, Burgess revealed that similar network reconnaissance activities have been detected within Australia. “We have seen Chinese hackers probing our critical infrastructure as well,” he said, warning that the same tactics could be used for sabotage or pre-positioning for future disruption.
China’s embassy in Canberra did not comment on the accusations, though Beijing routinely denies involvement in cyber espionage.
Economic and National Security Implications
Burgess cautioned that a successful cyberattack on core infrastructure — from telecommunications and financial systems to water and power grids — could cripple the economy and affect daily life across the country. “These are not hypotheticals — foreign governments have elite teams investigating these possibilities right now,” he said.
Beyond critical infrastructure, Burgess also highlighted risks of data manipulation and election interference, saying adversaries could use cyber intrusions to destabilize companies, influence public sentiment, or cause panic.
Despite repeated diplomatic pushback from China, ASIO maintains that cyber espionage and sabotage remain the most immediate threats to Australia’s national security.
