Historical Climate Events
Major flooding along the Murray River impacted Goolwa North, inundating low-lying areas and causing property damage.
SourceA prolonged heatwave in January 2013 resulted in record-breaking temperatures and increased heat stress in Goolwa North.
SourceAnother significant heatwave event in January 2019 caused widespread discomfort and placed strain on local resources.
SourceHigh river flows in the Murray River caused minor flooding in low-lying areas of Goolwa North.

Learn moreAbout Goolwa North's Climate Risk Profile
Goolwa North, located near the mouth of the Murray River, is vulnerable to a range of climate-related hazards. The primary risks include heatwaves, flooding (both riverine and stormwater), coastal erosion, and bushfire.
Heatwaves pose a significant threat, particularly to elderly and vulnerable populations. The region is projected to experience more frequent, intense, and longer-lasting heatwaves in the future. Flooding is also a concern, with the potential for both riverine flooding from the Murray River and stormwater flooding during heavy rainfall events.
Coastal erosion is a growing risk due to sea level rise and increased storm surge. The low-lying areas near the coast are particularly vulnerable. While not immediately surrounded by dense bushland, Goolwa North is susceptible to grassfires and ember attacks during hot, dry conditions.
Addressing these climate risks requires a combination of adaptation and mitigation strategies. Residents and businesses should take steps to prepare for extreme weather events, such as developing emergency plans and investing in property-level adaptation measures. Local and state governments need to implement policies to reduce greenhouse gas emissions and build resilience to climate change impacts.
