Australia’s domestic intelligence agency has issued a stark warning about the growing risk of “high-impact sabotage” from Chinese-linked hackers targeting the nation’s critical infrastructure. According to Mike Burgess, Director-General of the Australian Security Intelligence Organisation (ASIO), cyberattacks from groups linked to the Chinese government and military pose an unprecedented threat to Australia’s national security and economic stability.
Speaking at a business forum in Melbourne, Burgess described the current cyber landscape as one of “unprecedented levels of espionage and interference”, warning that the next five years could see cyber-enabled attacks designed to cripple key sectors such as energy, water, telecommunications, and transport.
China-Linked Hacker Groups Identified
While Burgess refrained from directly naming China, he made it clear that one nation-state actor was repeatedly attempting to infiltrate Australia’s most sensitive networks — a reference widely interpreted to mean Beijing. He also confirmed that Australia’s allies, including the United States and the United Kingdom, are facing similar cyber threats.
Among the most active hacker groups are Salt Typhoon and Volt Typhoon, both alleged to have direct or indirect ties to the Chinese military cyber units. Burgess explained that Salt Typhoon focuses primarily on espionage, infiltrating telecommunications networks to steal sensitive data, while Volt Typhoon is more disruptive, mapping out and compromising infrastructure systems for potential future sabotage.
“These groups are highly sophisticated, using advanced tradecraft to find vulnerabilities, maintain undetected access, and prepare for possible disruption,” Burgess warned.
“Once inside, they don’t just steal data — they map entire networks, positioning themselves to launch sabotage operations when it suits them.”
Preparing for Potential Sabotage
Burgess warned that the growing aggression of authoritarian regimes in cyberspace poses a new form of warfare that could directly harm civilians. Even limited interference, he said, could paralyze essential systems, impede government response, and trigger national panic.
“Imagine if a hostile nation could disable power grids during a heatwave, contaminate water supplies, or bring down financial systems,” he said. “The resulting chaos would be catastrophic for public safety and national confidence.”
The ASIO chief explained that cyber sabotage is not a distant threat but an emerging reality, with hackers already probing Australia’s energy networks, water treatment plants, and telecom infrastructure. These incursions, he said, are often disguised as espionage operations but serve a dual purpose: gathering intelligence while quietly preparing for potential attacks.
The Economic Toll of Espionage
Beyond sabotage, espionage itself has become a major economic liability. Burgess revealed that espionage cost Australia an estimated A$12.5 billion ($8.2 billion) in 2023–24, including roughly $2 billion in stolen intellectual property and trade secrets from private Australian companies.
He warned that cyber espionage has expanded beyond defense and government sectors to target private sector projects, investment negotiations, and critical supply chains, giving foreign corporations and state entities unfair commercial advantages.
“Every stolen file, trade secret, and business plan represents lost Australian innovation and prosperity,” Burgess said. “This is not just about national security — it’s about protecting our economy and our future.”
A Call for Stronger Cyber Defenses
Burgess urged both government and private organizations to take urgent and coordinated action to strengthen cyber defenses. He emphasized that hackers linked to state actors are persistent and patient, often maintaining undetected access to networks for months or even years before activating their attacks.
“Hackers don’t just steal information; they actively prepare for potential sabotage,” he said. “Australia must fortify its critical infrastructure and private sector networks to prevent catastrophic disruption.”
His remarks follow a series of high-profile international cyber incidents, including breaches of the US Treasury Department and Microsoft systems by China-based hackers. In response, Microsoft has restricted several Chinese firms from accessing its cybersecurity threat-sharing programs, citing national security concerns.
A Shifting Global Cyber Landscape
The warning from ASIO underscores a broader global shift in how nations view cyberspace as a battlefield. Espionage, sabotage, and data theft are increasingly being used as tools of statecraft, allowing governments to project power and influence without traditional military engagement.
Experts warn that as artificial intelligence and quantum computing continue to advance, cyber threats could become even more covert, complex, and destructive. The Australian government has already announced plans to expand its cybersecurity strategy, strengthen collaboration with private industries, and enhance its offensive cyber capabilities to deter hostile actors.
The ASIO chief also encouraged Australian businesses to prioritize cybersecurity at the executive level, noting that even minor system vulnerabilities can expose entire industries. He emphasized the importance of public-private partnerships, real-time threat intelligence sharing, and rapid incident response frameworks to safeguard national interests.
A Wake-Up Call for Australia
Burgess’s address comes at a time of heightened geopolitical tension between Australia and China, following a series of diplomatic disputes over trade, defense cooperation, and foreign interference. The intelligence chief’s warning serves as both a national security alert and a call to action for Australian institutions to prepare for the digital conflicts of the future.
As cyber threats evolve in scale and sophistication, experts agree that Australia must balance openness and technological innovation with robust protection against espionage and sabotage. The cost of complacency, Burgess warned, could be devastating.
“We are entering an era where cyber warfare can cripple economies, disrupt societies, and threaten lives,” he concluded. “Our best defense is vigilance, preparedness, and unity across government, industry, and the public.”
