Learn moreAbout Augusta-Margaret River's Climate Risk Profile
Augusta-Margaret River, located in the southwest of Western Australia, is known for its stunning coastline, vineyards, and forests. However, the region is increasingly vulnerable to the impacts of climate change.
Bushfire risk is a major concern, with hot, dry summers creating ideal conditions for wildfires. Changes in rainfall patterns and increased temperatures are exacerbating this risk. Flooding is also a significant threat, particularly in low-lying areas near rivers and the coast. Intense rainfall events can lead to flash flooding and riverine flooding.
Sea level rise poses a long-term threat to coastal communities, with potential for erosion and inundation. Rising temperatures are also impacting the region's ecosystems and agricultural industries. The local council is working to develop strategies to mitigate and adapt to these challenges.
Residents and property owners should take steps to prepare for extreme weather events, including developing emergency plans and ensuring adequate insurance coverage. Investing in climate-resilient infrastructure and promoting sustainable land management practices are also crucial for protecting the region's future.
