Australia could be cut off from the internet in a matter of hours if a regional conflict erupts, warns a top defence expert.
The nation’s digital infrastructure is vulnerable to cyberattacks, which could cripple Australia’s internet, communications, banking, emergency services, and more.
Mike Pezzullo, former Deputy Secretary of Defence, explains that any future conflict wouldn’t begin with missiles or bombs, but with cyberattacks designed to disable Australia’s digital backbone.
Australia’s Weaknesses Exposed
With 99% of the nation’s internet traffic flowing through just 15 undersea cables, enemy submarines could easily sever these critical lines, leaving Australia digitally isolated.
Beyond the cyber threat, Australia faces multiple vulnerabilities, including targeted missile strikes on key infrastructure, such as air bases, radar facilities, and defence logistics.
The nation’s fuel supplies are also a concern, with 90% of Australia’s oil and petrol flowing through the South China Sea – a region where any Taiwan conflict would likely unfold.
Defence Assets Visible on Google Maps
Billions of dollars’ worth of defence aircraft are sitting exposed on tarmacs, visible to anyone with access to Google Maps satellite imagery, making them vulnerable to low-cost drone strikes.
Australia’s fleet of P-8A Poseidon maritime surveillance jets and C-17A transport aircraft are clearly visible on public satellite imagery, with no protective cover.
Playing Catch-Up
While Australia has major defence projects underway, including AUKUS nuclear submarines, new frigates, cruise missiles, and underwater drones, these efforts are still years from completion.
Mr Pezzullo believes Australia’s defence budget will need to rise from its current level to three or even three-and-a-half per cent of GDP to adequately deter adversaries and defend the nation.
Counter-Drone Defence Underway
Defence officials are taking the drone threat seriously, with Project Land 156 launched to develop counter-drone systems, and Mission Syracuse focusing on advanced drone intercepting technology.
Modern counter-drone systems use various methods to detect and neutralise threats, including signal disruption and physical destruction.
Australia’s Strategic Priorities
Despite the challenges, Mr Pezzullo remains clear about Australia’s strategic priorities: “Plan A is always peace through diplomacy. But if you want peace, prepare for war.”
