About Quandary's Climate Risk Profile

Quandary, NSW, is a suburb that will likely experience increased climate-related challenges in the coming decades. The primary concerns are flooding due to more intense rainfall, and heatwaves becoming more frequent and severe. Bushfire risk is also a factor, particularly during dry periods.

The risk of flooding is driven by increased rainfall intensity and potential riverine overflow. Inadequate drainage infrastructure could exacerbate the problem. Residents should be aware of flood warnings and have evacuation plans in place.

Heatwaves pose a significant threat to vulnerable populations, such as the elderly and those with chronic health conditions. Rising average temperatures and the urban heat island effect will contribute to this risk. Access to cooling centers and community support networks will be crucial.

While the coastal risk is low due to its inland location, the suburb should still consider broader regional impacts of climate change. This includes potential disruptions to supply chains and increased demand on emergency services.

Adaptation measures, such as improved drainage, urban greening, and community awareness programs, are essential to mitigate the impacts of climate change in Quandary.
