Australia at Risk of Major Cyber Sabotage from China-Linked Hackers, Warns ASIO Chief
Australia is facing an escalating threat of “high-impact cyber sabotage” from state-backed hackers tied to the Chinese government and military, the head of the Australian Security Intelligence Organisation (ASIO) has warned.
Speaking at a business forum in Melbourne, ASIO Director-General Mike Burgess described “unprecedented levels of espionage” targeting Australia and cautioned that the next five years could bring cyberattacks capable of crippling vital national infrastructure.
Sensitive National Systems Under Persistent Probing
Burgess pointed to a single adversarial nation—understood to be China—as repeatedly attempting to infiltrate Australia’s most sensitive networks. These include water systems, transportation, telecommunications networks, and energy grids. He noted that allied countries are also being targeted in similar campaigns.
The Chinese embassy has been contacted for comment.
Salt Typhoon and Volt Typhoon Highlight Growing Threat
The ASIO chief identified two Chinese hacking groups as particularly concerning:
Salt Typhoon – primarily focused on espionage, infiltrating telecommunications networks to steal confidential information.
Volt Typhoon – more destructive in intent, targeting critical infrastructure with the capacity to enable future acts of sabotage.
Both groups, he said, have actively probed Australian systems and possess highly advanced capabilities.
“These groups use sophisticated tradecraft to locate networks, test vulnerabilities, and maintain long-term undetected access,” Burgess said. “Once inside, they meticulously map systems—preparing for sabotage at a time and place that suits them.”
Potential for Catastrophic Disruption
Burgess warned that authoritarian regimes are increasingly prepared to disable or destroy critical systems to obstruct government decision-making, undermine military readiness, damage the economy, and fuel societal division.
He emphasized how even brief network outages have demonstrated the fragility of modern communication and digital infrastructure.
“Imagine if a hostile nation disabled networks nationwide, cut power during a heatwave, contaminated water supplies, or collapsed financial systems,” he said. “The consequences would be catastrophic.”
Economic Costs Already Mounting
ASIO estimates that espionage drained A$12.5 billion (US$8.2 billion; £6.2 billion) from the Australian economy in 2023–24. Roughly A$2 billion of this stemmed from stolen trade secrets and intellectual property.
Burgess said Australian companies are increasingly targeted, with foreign competitors seeking access to sensitive commercial projects, negotiations, investment plans, and customer data.
A Call for Stronger Cyber Defences
Burgess urged immediate action to bolster cybersecurity across government and the private sector, stressing that hackers are not merely stealing information—they are actively preparing the ground for potential sabotage.
“Australia must strengthen the defences protecting its critical infrastructure and private-sector networks,” he said. “The threat is evolving quickly, and our response must evolve just as fast.”
Australia now finds itself on the front lines of a fast-intensifying cyber conflict, where espionage, disruption, and sabotage have become powerful instruments of statecraft.
As adversaries grow more sophisticated and aggressive, protecting national security and economic stability will require unprecedented vigilance.
