About Katherine's Climate Risk Profile

Katherine is located in the Northern Territory, approximately 320 kilometers southeast of Darwin. The town is situated on the banks of the Katherine River and is a major service center for the surrounding pastoral and agricultural industries.

The primary climate risks for Katherine are flooding, heatwaves, and bushfires. The Katherine River is prone to flooding during the wet season, and the town has experienced several major flood events in the past. Rising temperatures are increasing the frequency and intensity of heatwaves, posing a threat to public health, especially for vulnerable populations.

The surrounding savanna grasslands and woodlands are susceptible to bushfires during the dry season. Prolonged dry periods and high temperatures increase the risk of fire ignition and spread. Changes in rainfall patterns and increased fuel loads are also contributing to the bushfire risk.

While Katherine is not directly exposed to coastal risks, the broader Northern Territory coastline is vulnerable to sea level rise and coastal erosion. These changes could indirectly impact Katherine through disruptions to supply chains and infrastructure.
