Is Fremantle, WA Climate Safe? 2026 Assessment
Climate Safety Score
5.2/10Moderate climate risk — address-specific
Key Facts
- Climate Safety
- Medium
- Flood
- Fremantle faces a moderate risk of flooding, primarily from heavy rainfall and storm surges. The low-lying areas near the coast and the Swan River are particularly vulnerable.
- Bushfire
- Bushfire risk in Fremantle is relatively low due to its urban environment and coastal location. However, areas bordering parks and reserves may experience some risk.
- Heat
- Fremantle is experiencing increasing heatwave frequency and intensity. The urban heat island effect exacerbates the impact, particularly in densely built areas.
- Storm
- Moderate storm risk — winter storms and occasional severe thunderstorms
- Postcode
- 6160
- Highest high-risk exposure
- 14.9% of land (bushfire)
Climate Safety Analysis
Fremantle in Western Australia 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 Fremantle's climate safety include heat, coastal. 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 Fremantle 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.

Fremantle (postcode 6160) is tracked in ClimateNest's suburb hazard model, which maps the share of the suburb's land exposed to each hazard at high and moderate levels. The suburb's highest high-risk exposures are bushfire (14.9% of land in high-risk zones), riverine flood (9.2% of land in high-risk zones), surface flood (4.9% of land in high-risk zones). Exposure is not uniform across Fremantle — individual properties can sit well above or below these averages, so an address-level check is recommended before buying, selling or insuring.

Which climate hazard poses the biggest risk in Fremantle?
The dominant hazard for Fremantle 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 Fremantle 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 Western Australia suburbs.
Should I be concerned about buying property in Fremantle?
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 Fremantle?
Key projections for Western Australia 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 Fremantle.
What share of Fremantle is exposed to high bushfire risk?
ClimateNest's hazard overlay maps 14.9% of Fremantle in high-risk zones for bushfire, with a further 73.2% in moderate-risk zones. Suburb-level exposure is not uniform — individual properties can differ from these averages, so an address-level check is recommended.
