About Sunnybank's Climate Risk Profile

Sunnybank, a suburb of Brisbane, Queensland, is increasingly vulnerable to the impacts of climate change. The primary risks stem from increased rainfall intensity leading to flooding, and rising average temperatures exacerbating heatwave events.

Flooding is a significant concern due to the suburb's proximity to creeks and low-lying areas. Urban development has reduced natural drainage, increasing the risk of flash flooding during intense rainfall. Climate projections indicate that rainfall intensity will continue to increase, further elevating flood risk.

Heatwaves are another growing threat. Rising average temperatures, combined with the urban heat island effect, will lead to more frequent and intense heatwaves. This poses a particular risk to elderly residents and those with pre-existing health conditions.

While bushfire risk is relatively low due to the urban nature of the suburb, it is not entirely absent. Areas bordering green spaces may experience some risk, particularly during dry periods. Coastal risks are minimal due to Sunnybank's distance from the coastline.

Addressing these climate risks requires a multi-faceted approach, including improved drainage infrastructure, heatwave preparedness plans, and community awareness campaigns.
