About Cowes's Climate Risk Profile

Cowes, located on Phillip Island, is a popular tourist destination known for its beaches and wildlife. However, the suburb faces several climate-related risks that are expected to worsen in the coming decades.

Flooding is a significant concern due to the low-lying coastal areas and proximity to waterways. Increased rainfall intensity and sea level rise will likely lead to more frequent and severe flooding events. Bushfire risk is also present due to surrounding vegetation, with hotter and drier conditions increasing the likelihood of fires.

Heatwaves are becoming more frequent and intense, posing a risk to vulnerable populations. Coastal hazards, including sea level rise and coastal erosion, threaten low-lying areas and infrastructure.

Adapting to these changes will require a combination of mitigation and adaptation strategies. Residents and businesses should take steps to prepare for extreme weather events, and local authorities should invest in infrastructure improvements to reduce climate risks.
