About South Fremantle's Climate Risk Profile

South Fremantle is a coastal suburb that is increasingly vulnerable to the impacts of climate change. The primary risks include coastal inundation from sea level rise and storm surges, as well as increasing heatwave frequency and intensity.

The suburb's low-lying coastal areas are particularly susceptible to flooding. Sea level rise is expected to exacerbate this risk, with potential for significant property damage and displacement of residents. Coastal erosion is also a concern, threatening infrastructure and recreational areas.

Heatwaves are becoming more frequent and intense, posing a health risk to vulnerable populations, such as the elderly and those with chronic health conditions. The urban heat island effect can further amplify these risks.

While bushfire risk is relatively low compared to other areas in Western Australia, nearby bushland areas still pose a potential threat, especially during dry and windy conditions.

Addressing these climate risks requires a combination of adaptation and mitigation strategies, including coastal protection measures, urban greening initiatives, and community awareness programs.
