About Mullaway's Climate Risk Profile

Mullaway, located in the Clarence Valley of New South Wales, is a suburb that is increasingly vulnerable to the impacts of climate change. The region is susceptible to a range of hazards, including flooding from heavy rainfall and coastal inundation, bushfires due to dry vegetation and rising temperatures, and heatwaves that can strain infrastructure and public health.

The risk of flooding in Mullaway is heightened by its proximity to waterways and low-lying areas. Climate change projections indicate an increase in rainfall intensity, which could lead to more frequent and severe flood events. This poses a threat to residential and commercial properties, as well as critical infrastructure.

Bushfire risk is also a significant concern for Mullaway. The surrounding bushland and grasslands create a potential fuel load, and hotter, drier conditions are expected to increase the frequency and intensity of bushfires. This could have devastating consequences for the community and the environment.

Heatwaves are becoming more common and intense in Mullaway, posing a risk to vulnerable populations such as the elderly and those with chronic health conditions. The increased demand for cooling during heatwaves can also strain the electricity grid, leading to power outages.

Coastal erosion and sea level rise are also threats to Mullaway, particularly for properties located near the coastline. These hazards could lead to property damage, loss of recreational areas, and displacement of residents.
