About Moonan Brook's Climate Risk Profile

Moonan Brook, located in the Upper Hunter region of New South Wales, is increasingly vulnerable to the impacts of climate change. The primary concerns are rising temperatures, increased bushfire risk, and more intense flooding events.

The risk of flooding is significant due to the proximity of the Hunter River and local creeks. Climate change is expected to increase rainfall intensity, leading to more frequent and severe flooding. Residents should stay informed about flood warnings and have evacuation plans in place.

Bushfire risk is also a major concern, with the surrounding bushland creating a high fuel load. Drier conditions and higher temperatures are expected to exacerbate bushfire risk, potentially threatening homes and livelihoods. Regular property maintenance and awareness of fire danger ratings are crucial.

Heatwaves are projected to become more frequent and intense, posing health risks, especially for the elderly and those with pre-existing conditions. Ensuring access to cooling and staying hydrated during heatwaves are essential adaptation measures.

While Moonan Brook is not directly exposed to coastal risks, the broader impacts of climate change, such as disruptions to supply chains and increased insurance costs, may still affect the community.
