A staggering half a billion dollars worth of infrastructure in Geelong is under threat from the impacts of climate change, according to a new report. The analysis, conducted by the City of Greater Geelong, identifies roads, drainage systems, and coastal assets as the most vulnerable to rising sea levels, extreme weather events, and increased flooding.
Infrastructure at Risk
The report highlights that over $500 million of public and private infrastructure is exposed to climate-related hazards. This includes major road networks, stormwater drains, and key community facilities located in low-lying areas. The Barwon River and Corio Bay foreshore are particularly susceptible to erosion and inundation.
Coastal Assets Most Vulnerable
Coastal infrastructure, such as seawalls, piers, and boat ramps, faces the greatest risk. With sea levels predicted to rise by up to 0.8 metres by 2100, these assets require significant investment to withstand future conditions. The report estimates that adaptation measures could cost tens of millions of dollars over the next few decades.
Drainage Systems Under Pressure
Stormwater drainage networks are also under increasing strain due to more intense rainfall events. Many existing systems are not designed to handle the volume of water expected in a changing climate, leading to flash flooding in urban areas. Upgrades to drainage infrastructure are urgently needed to protect homes and businesses.
Economic Implications
The financial burden of climate adaptation falls on both local government and private property owners. The report warns that without proactive investment, damage costs could escalate dramatically. For example, a single major flood event could cost tens of millions of dollars in repairs and lost productivity.
Community and Environmental Impact
Beyond economics, the report underscores the social and environmental consequences. Disruption to transport networks can isolate communities, while damage to natural habitats affects biodiversity. The City of Greater Geelong is working on a climate adaptation plan to address these challenges, but funding remains a critical issue.
Next Steps
The council is calling on state and federal governments to contribute to adaptation funding. Community consultation is underway to prioritise projects and ensure resilience measures align with local needs. The report serves as a stark reminder that climate change is not a future problem—it is already affecting Geelong's infrastructure and way of life.
