About Dorrigo's Climate Risk Profile

Dorrigo, located in the Northern Tablelands of New South Wales, is increasingly vulnerable to the impacts of climate change. The primary risks are associated with flooding and bushfires, both of which are projected to become more frequent and intense in the coming decades.

Increased rainfall intensity is expected to worsen flood risks, particularly in low-lying areas and near waterways. The town's infrastructure may struggle to cope with more extreme rainfall events, leading to property damage and disruption to essential services.

The risk of bushfires is also significant, given the town's proximity to extensive bushland. Drier conditions and higher temperatures create a more conducive environment for bushfires to ignite and spread rapidly, threatening homes and livelihoods.

Rising average temperatures and more frequent heatwaves will pose a growing threat to public health, especially for vulnerable populations such as the elderly and those with pre-existing medical conditions. Heat stress can lead to a range of health problems, including heatstroke and dehydration.

While Dorrigo is not directly exposed to coastal risks, the broader impacts of climate change, such as disruptions to supply chains and increased migration from coastal areas, could indirectly affect the town.
