How the region's climate is projected to change
Regional projections, not a forecast for this street. Figures are from the WA Department of Water and Environmental Regulation's climate projections for the South Western Flatlands region, which draws on CSIRO and Bureau of Meteorology modelling.
Temperature
+0.5 to 1.1°C by 2030
Above the 1986–2005 climate, on all emissions scenarios. By 2090, 1.2 to 2.0°C under intermediate emissions or 2.6 to 4.0°C under high emissions.
Rainfall
Winter rain down up to 15% by 2030
The South West has been drying since 1970, and the decline has been larger than anywhere else in Australia. Heavy rainfall events are projected to become more intense even as totals fall.
Fire weather
Harsher, magnitude uncertain
High confidence that fire weather becomes harsher, low confidence in the size of the change, because it depends heavily on summer rainfall.
Sea level
+0.12 m by 2030
At the Fremantle gauge, range 0.07 to 0.16 m. Very high confidence that sea levels continue to rise through the century.

Learn moreAbout Triabunna's Climate Risk Profile
Triabunna, located on the east coast of Tasmania, is increasingly vulnerable to the impacts of climate change. The primary risks include flooding from heavy rainfall and storm surges, as well as coastal erosion and inundation due to sea level rise. Bushfire risk is also a concern, particularly during dry periods. Heatwaves are becoming more frequent and intense, posing a threat to vulnerable populations.
The town's proximity to the coast makes it particularly susceptible to sea level rise and storm surges. Low-lying areas are at risk of permanent inundation, while coastal erosion threatens infrastructure and property. Changes in rainfall patterns are leading to more frequent and intense flooding events, impacting homes, businesses, and transportation networks.
Rising temperatures are exacerbating the risk of bushfires, particularly in areas with dense vegetation. Heatwaves are becoming more common, placing stress on the elderly and those with pre-existing health conditions. These climate-related risks require a coordinated response from local government, emergency services, and the community.
Adaptation measures are essential to protect Triabunna from the worst impacts of climate change. These include upgrading flood defenses, implementing coastal protection measures, improving bushfire preparedness, and developing heatwave response plans. Community engagement and education are also crucial to ensure that residents are aware of the risks and prepared to take action.
