About Killara's Climate Risk Profile

Killara, a suburb in northern Sydney, is increasingly vulnerable to the impacts of climate change. The primary risks include flooding from intense rainfall, heatwaves during the summer months, and bushfire risk due to surrounding bushland.

Flooding is a significant concern, with potential for property damage and disruption to daily life. Climate change is projected to increase rainfall intensity, leading to more frequent and severe flood events. Properties in low-lying areas near creeks are particularly at risk.

Heatwaves are becoming more common and intense, posing health risks to vulnerable populations such as the elderly and those with chronic illnesses. The urban heat island effect can further exacerbate temperatures in built-up areas.

Bushfire risk is present due to the suburb's proximity to bushland. Hot, dry conditions and strong winds can create a high fire danger, threatening homes and property.

While Killara is not directly exposed to coastal hazards, the broader impacts of climate change, such as disruptions to supply chains and infrastructure, can still affect the suburb.
