About Wolli Creek's Climate Risk Profile

Wolli Creek, located in the inner-south of Sydney, is increasingly vulnerable to the impacts of climate change. The suburb's low-lying geography and proximity to the Cooks River and Botany Bay make it particularly susceptible to flooding and coastal inundation. Rising sea levels and more intense rainfall events are expected to exacerbate these risks in the coming decades.

Heatwaves are also a growing concern for Wolli Creek residents. The urban environment contributes to the urban heat island effect, which can amplify temperatures during hot summer days. This poses a significant health risk, especially for vulnerable populations such as the elderly and those with pre-existing medical conditions.

While the risk of bushfire is relatively low due to the suburb's urban density, the potential for coastal erosion and inundation remains a significant threat. Sea level rise could lead to the loss of valuable coastal land and infrastructure, impacting property values and community amenities.

Addressing these climate risks will require a coordinated effort from local government, residents, and businesses. Implementing adaptation measures such as improved drainage systems, green infrastructure, and community awareness programs can help to build resilience and protect Wolli Creek from the worst impacts of climate change.
