Hazard Breakdown
Climate Hazard Breakdown for Wynnum
Flood
Wynnum faces a moderate risk of flooding due to its proximity to waterways and low-lying areas. Climate change is expected to increase rainfall intensity, potentially worsening flood events.
Key drivers:
- ·Increased rainfall intensity
- ·Sea level rise
Bushfire
The bushfire risk in Wynnum is relatively low compared to other regions in Tasmania, but it's still present due to nearby bushland. Drier conditions and higher temperatures could elevate this risk in the future.
Key drivers:
- ·Increased temperatures
- ·Drier conditions
Heat
Wynnum experiences moderate heat risk, with increasing average temperatures during summer. Heatwaves are expected to become more frequent and intense, impacting vulnerable populations.
Key drivers:
- ·Rising average temperatures
- ·Increased frequency of heatwaves
Coastal
Wynnum faces a high coastal risk due to its location near the coastline. Sea level rise and increased storm surges threaten coastal erosion and inundation of low-lying areas.
Key drivers:
- ·Sea level rise
- ·Increased storm surge
Wind
Notable wind risk — westerly wind storms
Storm
Moderate storm risk — occasional severe weather
Social
Lower social stability — regional isolation
Energy
Moderate energy costs — winter heating

Learn moreAbout Wynnum's Climate Risk Profile
Wynnum is a suburb in Tasmania that is increasingly vulnerable to the impacts of climate change. The primary risks include coastal inundation due to sea level rise, increased flooding from more intense rainfall events, and a higher frequency of heatwaves. These changes pose significant challenges to the local community and infrastructure.
The coastal risk is particularly concerning, as Wynnum's proximity to the coastline makes it susceptible to erosion and inundation. Sea level rise is projected to worsen over the coming decades, potentially impacting properties and infrastructure located near the shore. Storm surges could also become more frequent and intense, further exacerbating coastal hazards.
Flooding is another significant risk, with climate change expected to increase rainfall intensity. This could lead to more frequent and severe flood events, particularly in low-lying areas. Inadequate drainage infrastructure may also contribute to the problem, increasing the vulnerability of the suburb to flooding.
Rising temperatures and more frequent heatwaves pose a threat to public health, especially for vulnerable populations such as the elderly and those with chronic health conditions. The urban heat island effect could further amplify these risks, making it even hotter in built-up areas. Residents should take steps to prepare for extreme heat events, such as staying hydrated and seeking shelter in air-conditioned environments.
Addressing these climate risks will require a coordinated effort from local government, residents, and other stakeholders. Adaptation measures such as improving drainage infrastructure, protecting coastal areas, and implementing heatwave early warning systems can help to reduce the vulnerability of Wynnum to climate change. It is also important to reduce greenhouse gas emissions to mitigate the long-term impacts of climate change.
