About Mosman Park's Climate Risk Profile

Mosman Park, a suburb of Perth, Western Australia, is increasingly vulnerable to the impacts of climate change. Rising sea levels pose a significant threat to properties along the Swan River and the coastline. Coastal erosion is also a growing concern, potentially damaging infrastructure and natural habitats.

Heatwaves are becoming more frequent and intense, impacting the health of vulnerable residents, particularly the elderly and those with pre-existing conditions. The urban heat island effect exacerbates this issue, with built-up areas retaining more heat than surrounding areas.

While the risk of bushfire is relatively low compared to other parts of Western Australia, nearby reserves and parks still pose a potential threat, especially during dry periods. Residents should maintain their properties to reduce the risk of fire spreading.

Flooding is a moderate risk, primarily from heavy rainfall events and riverine overflow. Aging drainage infrastructure can exacerbate flooding issues, requiring ongoing maintenance and upgrades. The Town of Mosman Park is working to address these challenges through various adaptation strategies.

Addressing these climate risks requires a coordinated effort from residents, local government, and state agencies. Implementing adaptation measures, such as improving drainage infrastructure, protecting coastal areas, and promoting energy efficiency, is crucial to building resilience and ensuring a sustainable future for Mosman Park.
