Hazard Breakdown
Climate Hazard Breakdown for Manjimup
Flood
Manjimup faces a moderate risk of flooding, primarily from heavy rainfall events and riverine flooding along the Lefroy Brook and other local waterways. The risk is expected to increase with climate change due to more intense rainfall.
Key drivers:
- ·Increased rainfall intensity
- ·Riverine flooding
Bushfire
Manjimup has a high bushfire risk due to its proximity to extensive forests and bushland. Hot, dry summers and strong winds exacerbate the risk. Climate change is projected to increase the frequency and intensity of bushfires.
Key drivers:
- ·Dry vegetation
- ·Hot summers
Heat
Manjimup experiences moderate heat risk, with increasing average temperatures and more frequent heatwaves. This poses a risk to vulnerable populations and infrastructure.
Key drivers:
- ·Rising average temperatures
- ·Increased frequency of heatwaves
Coastal
Manjimup has a very low coastal risk due to its inland location. Sea level rise and coastal erosion are not direct threats to the suburb.
Key drivers:
- ·Inland location
Wind
Moderate wind risk — winter storms
Storm
Moderate storm risk — occasional severe thunderstorms
Social
Moderate social stability
Energy
Moderate energy costs — cooling demand in summer

Learn moreAbout Manjimup's Climate Risk Profile
Manjimup, located in the heart of the Southern Forests region of Western Australia, is increasingly vulnerable to the impacts of climate change. The primary risks include bushfires, flooding, and heatwaves, all of which are projected to worsen in the coming decades.
Bushfire risk is particularly high due to the extensive forests surrounding the town. Hot, dry summers and strong winds create ideal conditions for bushfires to ignite and spread rapidly. Climate change is expected to increase the frequency and intensity of these fires, posing a significant threat to lives and property.
Flooding is another concern, with the Lefroy Brook and other waterways prone to overflowing during heavy rainfall events. Inadequate drainage infrastructure in some areas exacerbates the problem. More intense rainfall, driven by climate change, will likely lead to more frequent and severe flooding.
Heatwaves are also becoming more common and intense, posing a risk to vulnerable populations, such as the elderly and those with chronic health conditions. Rising average temperatures will further exacerbate the heat risk, making it more difficult to cope with extreme heat events.
While Manjimup is not directly exposed to coastal risks, the broader region is affected by climate change impacts, such as changes in rainfall patterns and increased evaporation, which can affect water availability and agricultural productivity.
