Climate Hazard Breakdown for Orbost
Flood
Orbost faces a moderate risk of flooding due to its proximity to the Snowy River and other waterways. Climate change is expected to increase rainfall intensity, potentially leading to more frequent and severe flood events.
Key drivers:
- ·Increased rainfall intensity
- ·Riverine flooding
Bushfire
Orbost has a moderate risk of bushfire due to the surrounding forests and dry conditions during summer. Climate change is projected to increase the frequency and intensity of bushfires in the region.
Key drivers:
- ·Increased temperatures
- ·Drier conditions
Heat
Orbost is likely to experience more frequent and intense heatwaves due to climate change. This can pose a risk to vulnerable populations, such as the elderly and those with chronic health conditions.
Key drivers:
- ·Rising average temperatures
- ·Increased frequency of heatwaves
Coastal
Orbost is located inland and has a low risk of coastal hazards such as sea level rise and coastal erosion.
Key drivers:
- ·Distance from the coast

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 Orbost's Climate Risk Profile
Orbost is situated in a region that is increasingly vulnerable to the impacts of climate change. The primary concerns for Orbost are flooding from the Snowy River and surrounding waterways, as well as the increasing threat of bushfires due to hotter, drier conditions.
The risk of flooding is exacerbated by the potential for more intense rainfall events. The town's proximity to the Snowy River means that any increase in river levels can quickly impact residential and commercial areas. Improved drainage and flood mitigation strategies are essential to protect the community.
Bushfire risk is also a significant concern, with the surrounding forests providing ample fuel for fires. The combination of higher temperatures and lower rainfall increases the likelihood of severe bushfire seasons. Residents need to be prepared and aware of bushfire safety measures.
While coastal hazards are not a major concern for Orbost due to its inland location, the town will still experience the effects of climate change through more frequent and intense heatwaves. This can put a strain on the community's resources and pose health risks to vulnerable individuals.
Addressing these climate risks requires a coordinated effort from local government, emergency services, and the community. Investing in infrastructure improvements, implementing effective bushfire management strategies, and raising awareness about climate change impacts are crucial steps to ensure the long-term resilience of Orbost.
