Learn moreAbout Bankstown's Climate Risk Profile
Bankstown, located in the Canterbury-Bankstown region of New South Wales, is a diverse and densely populated suburb. Its proximity to the Georges River and other waterways makes it susceptible to flooding, particularly during periods of heavy rainfall. Climate change is projected to increase the intensity of rainfall events, potentially exacerbating flood risks in the area.
Heatwaves are another significant concern for Bankstown. As temperatures rise due to climate change, the suburb is likely to experience more frequent and intense heatwaves, posing a threat to public health, especially for vulnerable populations. The urban heat island effect, caused by the concentration of buildings and paved surfaces, can further amplify the impact of heatwaves.
While the risk of bushfire is lower compared to other parts of NSW, some areas of Bankstown near bushland reserves are still at risk. Drier conditions and higher temperatures can increase the likelihood of bushfires, potentially threatening homes and infrastructure.
Due to its inland location, Bankstown is not directly exposed to coastal hazards such as sea level rise or coastal erosion. However, the suburb may still be indirectly affected by climate change impacts, such as disruptions to supply chains or increased demand for resources.
