Learn moreAbout Sunbury's Climate Risk Profile
Sunbury, located in Victoria, is susceptible to several climate-related risks. The primary concerns are flooding due to its proximity to Jackson's Creek, and the increasing frequency and intensity of heatwaves. Bushfire risk is also a factor, given the surrounding grasslands and bushland.
Flooding events are expected to become more severe as climate change leads to increased rainfall intensity. This could impact residential areas and infrastructure near the creek. Heatwaves pose a significant threat to vulnerable populations, especially the elderly and those with pre-existing health conditions.
The bushfire risk is influenced by dry vegetation and high temperatures during the summer months. While not as immediate a threat as flooding or heatwaves, it remains a concern that requires ongoing vigilance and mitigation efforts.
Overall, Sunbury needs to focus on adaptation strategies to mitigate the impacts of climate change. This includes improving flood defenses, implementing heatwave management plans, and managing bushfire risks through controlled burns and community education.
