A new report by Infrastructure Victoria warns that more than $57 billion worth of public infrastructure across Victoria is at risk from extreme weather by 2030, with bushfires, flooding and heat posing the greatest threats. The independent adviser assessed risks to $318 billion in government-owned or regulated assets, finding that transport, energy and health assets were the most exposed to climate hazards. By 2070, the value at risk could increase to more than $71 billion, the report forecasts.

The report, titled "Warning Signs," is described by its authors as a first of its kind in Australia, showing how extreme weather events will impact infrastructure across Victoria in 2030 and projecting a "worst case" scenario for 2070.

Coverage Comparison

ABC Australia reported that $57 billion worth of infrastructure in Victoria is at risk from natural disasters, echoing the Guardian's report of more than $57 billion in public infrastructure at risk due to climate hazards. Both outlets highlighted the role of climate change as the primary driver of increasing risk, with ABC noting the report's forecast that costs could blow out beyond $71 billion in the coming decades. The Guardian similarly stated that the value at risk could increase to more than $71 billion by 2070.

While both outlets focused on the economic costs of natural disasters on infrastructure, ABC provided additional detail on the report's scope, noting that it looked at $318 billion worth of state-owned or regulated public networks and assets. The Guardian's coverage emphasized the sectors most exposed, naming transport, energy, and health assets.

Key Claims

  • At least $57 billion worth of infrastructure in Victoria is at risk from natural disasters, as reported by ABC Australia and The Guardian.
  • The report published by Infrastructure Victoria looked at $318 billion worth of state-owned or regulated public networks and assets, according to ABC Australia.
  • The value at risk could increase to more than $71 billion by 2070, as reported by both ABC Australia and The Guardian.
  • Melbourne's road and rail networks will incur the greatest costs in infrastructural damage from natural disasters, as reported by ABC Australia.
  • The report identifies roads, rail, energy infrastructure, and health assets as the most vulnerable sectors, according to ABC Australia.
  • The climate hazards with the highest potential costs are bushfires, followed by floods and extreme heat, as reported by ABC Australia.
  • Bushfires, flooding, and heat pose the greatest threat to infrastructure, as reported by The Guardian.
  • Transport, energy, and health assets are the most exposed to climate hazards, according to The Guardian.

Perspectives

Infrastructure Victoria

The report's authors, led by CEO Jonathan Spear, stress the urgency of adapting infrastructure to climate change. Spear said the research highlights which assets are most exposed, which climate risks matter most, and where risks are concentrated across the state. He added that it shows where the Victorian government should act now to reduce future damage, service disruption, and millions in recovery costs. The report emphasizes that the financial fallout from these hazards could be mitigated by cost-effective actions and funding measures to safeguard infrastructure now.

Climateworks Centre

Erwin Jackson, head of Australia programs at Climateworks Centre, who was not involved in the research, commented on the need for high-level policy integration. He said policies need to start integrating both reducing emissions and adaptation, while focusing on key risks such as heat, bushfire, and coastal inundation. Jackson noted that the scale of investment required to make infrastructure more resilient is a challenge, so governments need to identify the most vulnerable communities and assets and work with the private sector to unlock investment in adaptation and resilience building.
