Learn moreAbout Devonport's Climate Risk Profile
Devonport, located on the north coast of Tasmania, is increasingly vulnerable to the impacts of climate change. The primary risks stem from its coastal location and proximity to the Mersey River, making it susceptible to flooding and coastal erosion.
Rising sea levels pose a significant threat to low-lying areas, potentially inundating properties and infrastructure. Increased storm surge events could further exacerbate coastal flooding, causing damage and disruption to the community. The Mersey River also presents a flood risk, with more intense rainfall events leading to increased riverine flooding.
While bushfire risk is relatively lower compared to other parts of Tasmania, it is still a concern, especially during drier periods. Increased temperatures and changes in vegetation patterns could elevate the risk of bushfires in the surrounding areas.
Heatwaves are also expected to become more frequent and intense, potentially impacting vulnerable populations and placing strain on infrastructure. Adapting to these changes will require proactive measures to protect the community and its assets.
Addressing these climate risks will require a coordinated effort involving local government, residents, and other stakeholders. Implementing adaptation strategies, such as improving drainage infrastructure, protecting coastal areas, and promoting community awareness, will be crucial in building resilience to climate change.
