About Woronora's Climate Risk Profile

Woronora, located in New South Wales, is susceptible to a range of climate-related hazards. The suburb's proximity to the Woronora River increases its vulnerability to flooding, particularly during periods of heavy rainfall. Climate change is expected to exacerbate this risk, with projections indicating more intense rainfall events in the future.

The surrounding bushland also poses a significant bushfire threat to Woronora. Hotter, drier conditions increase the likelihood of bushfires, which can spread rapidly and threaten homes and infrastructure. Residents need to be vigilant and prepared for bushfire season.

Rising temperatures and more frequent heatwaves are another concern for Woronora. Vulnerable populations, such as the elderly and those with chronic health conditions, are particularly at risk during extreme heat events. Access to cooling and adequate hydration are essential for mitigating the health impacts of heatwaves.

Finally, sea level rise and storm surges pose a coastal risk to Woronora, potentially impacting properties along the Woronora River. While the immediate coastline is further away, the river acts as a conduit for coastal impacts. Long-term planning and adaptation measures are necessary to address this risk.
