About Eltham's Climate Risk Profile

Eltham, located in the Nillumbik Shire, is a suburb characterized by its leafy environment and proximity to natural bushland. This environment, while aesthetically pleasing, also presents significant climate-related challenges.

The primary risks facing Eltham are flooding, bushfires, and heatwaves. Flooding is a concern due to the presence of Diamond Creek and other waterways, which can overflow during periods of heavy rainfall. Bushfires pose a threat due to the surrounding bushland, which can become dry and highly flammable during the summer months. Heatwaves are also becoming more frequent and intense, impacting the health and well-being of residents.

Climate change is expected to exacerbate these risks. Rising temperatures, changes in rainfall patterns, and more frequent extreme weather events will increase the likelihood and severity of floods, bushfires, and heatwaves. This will have significant implications for the community, including damage to property, disruption to services, and increased health risks.

To mitigate these risks, it is essential that residents take proactive steps to prepare for climate change. This includes developing emergency plans, maintaining properties to reduce fire risk, and taking steps to stay cool during heatwaves. The local council also has a role to play in implementing climate adaptation strategies, such as improving drainage infrastructure, managing bushland, and providing support to vulnerable residents.
