Learn moreAbout Kellyville's Climate Risk Profile
Kellyville, located in the Hills District of Sydney, is increasingly vulnerable to climate change impacts. The primary risks are associated with flooding due to increased rainfall intensity and urban development that reduces natural drainage. Properties near Cattai Creek are particularly susceptible.
Bushfire risk is moderate, especially in areas bordering bushland. Hot, dry summers increase the likelihood of bushfires, posing a threat to homes and infrastructure. Residents should maintain firebreaks and be prepared to evacuate if necessary.
Heatwaves are becoming more frequent and intense, posing health risks to vulnerable populations, especially the elderly and those with chronic conditions. The urban heat island effect exacerbates these risks.
While coastal risks are minimal due to Kellyville's inland location, the suburb is still indirectly affected by broader climate change impacts on the region. Preparing for these challenges is essential to ensure the community's long-term resilience.
