The risk of bushfire in Trevallyn is moderate, influenced by nearby bushland and dry conditions during summer. Climate change may lead to longer fire seasons.
Key drivers:
- ·Longer fire seasons
- ·Increased dry spells
Heat
Trevallyn is likely to experience more frequent and intense heatwaves. This poses a risk to vulnerable populations and infrastructure.
Key drivers:
- ·Rising average temperatures
- ·Increased frequency of heatwaves
Coastal
Coastal risks are low in Trevallyn due to its inland location. Sea level rise and coastal erosion are not significant concerns.
Key drivers:
- ·Inland location
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 Trevallyn's Climate Risk Profile
Trevallyn, a suburb of Launceston, Tasmania, is increasingly vulnerable to the impacts of climate change. The primary concerns are flooding due to its proximity to the Tamar River, and the increasing frequency and intensity of heatwaves.
The risk of flooding is exacerbated by increased rainfall intensity and potential urban development that reduces natural drainage. Bushfire risk is also a concern, particularly during dry summer months, due to the presence of nearby bushland.
Heatwaves are becoming more frequent and intense, posing a threat to vulnerable populations, such as the elderly and those with pre-existing health conditions. Infrastructure may also be affected by extreme heat.
While coastal risks are minimal due to Trevallyn's inland location, the suburb is not immune to the broader impacts of climate change affecting the region. Adaptation measures are crucial to mitigate these risks and protect the community.
