About Millers Forest's Climate Risk Profile

Millers Forest, located in the Hunter region of New South Wales, is increasingly vulnerable to the impacts of climate change. The primary risks are associated with flooding from the Hunter River and more frequent and intense heatwaves. Bushfire risk is also a concern due to surrounding bushland.

Climate projections indicate that rainfall intensity will increase, leading to a higher risk of flooding. The low-lying areas of Millers Forest are particularly susceptible. Residents should be aware of flood warnings and have evacuation plans in place.

Heatwaves are expected to become more common and severe, posing a threat to public health, especially for vulnerable populations. Ensuring access to cooling centers and implementing heat-health action plans are crucial adaptation measures.

While coastal risks are relatively low, the broader region will experience sea level rise, which could indirectly affect Millers Forest through economic and social disruptions. Monitoring and planning for these potential impacts are important.

Addressing climate change in Millers Forest requires a combination of mitigation and adaptation strategies. Reducing greenhouse gas emissions and implementing local adaptation measures will help protect the community from the worst impacts of climate change.
