Is Cassilis, VIC Climate Safe? 2026 Assessment
Climate Safety Score
5.5/10Moderate climate risk — address-specific
Key Facts
- Climate Safety
- Medium
- Flood
- Cassilis faces a moderate risk of flooding due to its proximity to the Munmurra River and associated creeks. Intense rainfall events can cause these waterways to overflow, impacting low-lying areas within the suburb.
- Bushfire
- Cassilis is located in a region with a high bushfire risk. The surrounding bushland creates a significant fuel load, and dry conditions coupled with strong winds can lead to rapid fire spread.
- Heat
- Cassilis experiences moderately high temperatures during summer, with the potential for heatwaves. Climate change is expected to increase the frequency and intensity of heat events, posing a risk to vulnerable populations.
- Storm
- Moderate storm risk — severe thunderstorms with hail and damaging winds
- Postcode
- 3898
- Highest high-risk exposure
- 16.7% of land (bushfire)
Climate Safety Analysis
Cassilis in Victoria has an overall climate safety rating of Medium. This multi-hazard assessment combines flood, bushfire, heat, coastal, and storm risk data with climate projections to 2050 from CSIRO and the Bureau of Meteorology.
Key factors affecting Cassilis's climate safety include flood, bushfire. Each hazard is assessed independently and combined for an overall picture. Australia has warmed by approximately 1.5 °C since 1910, with flow-on effects to fire weather, extreme rainfall, and heatwave frequency.
Climate safety for property in Cassilis is not uniform — it varies by address. Factors such as elevation, distance to waterways, proximity to bushland, and local drainage all influence actual risk at a specific property. Two nearby properties can have materially different risk profiles.

Which climate hazard poses the biggest risk in Cassilis?
The dominant hazard for Cassilis depends on geography and local environment. Proximity to waterways elevates flood risk, while proximity to bushland increases bushfire risk. ClimateNest's multi-hazard analysis identifies the highest-risk hazards for any specific address.
How does Cassilis compare to nearby suburbs for climate safety?
Nearby suburbs may have different climate risk profiles depending on elevation, vegetation cover, drainage patterns, and land use. ClimateNest allows comparison of climate safety scores across Victoria suburbs.
Should I be concerned about buying property in Cassilis?
Climate risk should be one factor in your decision, alongside price, location, and amenity. An informed buyer understands the specific risks at a property address and factors insurance costs and climate projections into their assessment of long-term value.
What climate projections should I know for Cassilis?
Key projections for Victoria from CSIRO include increased average temperatures, more frequent hot days, changes in rainfall seasonality, longer fire seasons, and potential increases in extreme rainfall intensity. These trends inform the long-term outlook for Cassilis.
