About Gosnells's Climate Risk Profile

Gosnells, located in Western Australia, is subject to several climate-related risks. The primary concerns are flooding due to its proximity to the Canning River, and increasing heatwave frequency and intensity during the summer months. Bushfire risk is also present, particularly in areas adjacent to bushland.

Flooding in Gosnells can occur due to heavy rainfall events, leading to both riverine and flash flooding. Climate change is projected to increase rainfall intensity, potentially worsening flood events. The urban environment can also exacerbate flooding due to increased runoff.

Heatwaves are becoming more frequent and intense in Western Australia, posing a significant risk to the health of residents, especially the elderly and those with pre-existing conditions. The urban heat island effect can further amplify temperatures in built-up areas.

Bushfire risk is a concern during the dry summer months. While Gosnells is not directly adjacent to large areas of dense forest, the presence of bushland nearby means that the risk of bushfires impacting the suburb is present. Residents should be prepared and aware of bushfire safety measures.

Coastal risks are minimal in Gosnells due to its inland location, mitigating concerns about sea level rise and coastal erosion.
