Australia's Victoria State warns of rising climate risk to infrastructure
Melbourne, May 19
More than 57 billion Australian dollars worth of infrastructure in the Australian state of Victoria is at risk from climate-related extreme weather, said a report released Tuesday.
The amount of infrastructure at risk is projected to rise by nearly 25 per cent over the next four decades, said the report by Infrastructure Victoria, the Australian state's independent infrastructure adviser.
The report examined 318 billion Australian dollars' worth of assets across Victoria and identified bushfires, floods and extreme heat as the greatest risks.
It estimates that more than 23 billion Australian dollars in infrastructure is currently exposed to bushfire risk, rising to over 30 billion Australian dollars by 2070, while flood risk already affects assets worth over 22 billion Australian dollars, Xinhua news agency reported.
Infrastructure exposed to extreme heat is projected to more than double between 2030 and 2070, the report showed.
Road and rail networks are expected to bear the highest damage costs, particularly in the state capital Melbourne and key regional corridors, it said, adding that energy infrastructure and health assets are also at risk from floods, bushfires and extreme heat.
Extreme weather cost Victoria an average of 2.7 billion Australian dollars a year in the decade to 2016, with the 2022 floods alone triggering 3.5 billion Australian dollars in government spending on relief and recovery, the report said.
Victoria has already experienced rising climate impacts, with average temperatures increasing by 1.2 degrees Celsius since 1910, the Australian Broadcasting Corporation reported.
Infrastructure Victoria said targeted adaptation measures, such as improved drainage maintenance and climate-resilient road materials, could significantly reduce future damage, noting that every dollar invested in resilience can yield multiple economic benefits.
Australia spans multiple climate zones, with the northern third featuring a tropical climate (wet and dry seasons) and the southern two-thirds experiencing temperate conditions. About 70 per cent of the continent is arid or semi-arid desert. The seasons are the reverse of the Northern Hemisphere: summer runs from December to February, and winter from June to August.

As someone from Australia, I can vouch for the reality of these numbers. The 2022 floods in Victoria were devastating, and we saw how unprepared our infrastructure was. The report's suggestion about climate-resilient road materials makes sense—our roads buckle under extreme heat. But 57 billion AUD is a huge number; I hope the government follows through on adaptation instead of just talking.
The report mentions that every dollar invested in resilience yields multiple economic benefits. That's a powerful message for India too, where we often prioritize immediate spending over long-term planning. It's good to see Victoria taking a proactive approach, but I wonder if they'll actually implement the recommendations or if it'll just be another report gathering dust 🤔
I'm an infrastructure engineer in Melbourne, and I can tell you firsthand that our rail networks are struggling with heat-related track buckling. The projected 25% increase in at-risk assets by 2070 is alarming because it's not that far away—our kids will be dealing with this. The report is spot-on about targeted measures like improved drainage, but we also need to think about relocating some critical assets away from floodplains.
Seeing these numbers makes me think about our own cities like Mumbai and Chennai, where infrastructure is already stressed by monsoons and heatwaves. The difference is that Victoria has the resources to plan ahead, while we often react after disasters. Still, it's reassuring to see a state government taking climate risk seriously—wish our state governments did the same! 😅
