About Fremantle's Climate Risk Profile

Fremantle, a coastal suburb of Perth, is increasingly vulnerable to the impacts of climate change. Rising sea levels pose a significant threat to low-lying areas, increasing the risk of coastal inundation and erosion. The frequency and intensity of heatwaves are also projected to increase, placing stress on infrastructure and public health.

Flooding from heavy rainfall and storm surges is another concern for Fremantle. The Swan River and the suburb's proximity to the coast make it susceptible to both riverine and coastal flooding. Climate change is expected to exacerbate these risks, with more intense rainfall events and higher sea levels.

While bushfire risk is relatively lower compared to other areas in Western Australia, nearby bushland areas could still pose a threat under extreme conditions. It's important to maintain vegetation management practices to minimize this risk.

Addressing these challenges requires a coordinated effort from local government, residents, and businesses. Implementing adaptation measures such as coastal protection, improved drainage systems, and heatwave preparedness plans is crucial to building resilience in Fremantle.
