About Collie's Climate Risk Profile

Collie is situated in the south-west of Western Australia, an area known for its diverse landscapes and natural resources. The town's climate is typically Mediterranean, with warm, dry summers and mild, wet winters. However, climate change is expected to alter these patterns, leading to more extreme weather events.

Flooding is a concern due to the presence of the Collie River and other waterways. Increased rainfall intensity could lead to more frequent and severe flooding, impacting homes, businesses, and infrastructure. Bushfires also pose a threat, particularly during the dry summer months. Higher temperatures and drier conditions can create a more conducive environment for bushfires to ignite and spread rapidly.

Heatwaves are projected to become more frequent and intense, posing risks to vulnerable populations, such as the elderly and those with chronic health conditions. The town's infrastructure may also be affected, with increased demand for electricity and potential disruptions to transportation networks.

While Collie is not directly exposed to coastal hazards, the broader region could experience impacts from sea level rise and coastal erosion. These changes could indirectly affect Collie through economic and social disruptions.
