Hazard Breakdown
Climate Hazard Breakdown for Fremantle
Flood
Fremantle faces a moderate risk of flooding due to its proximity to waterways and low-lying areas. Climate change is expected to increase rainfall intensity, potentially exacerbating flood events.
Key drivers:
- ·Increased rainfall intensity
- ·Sea level rise
Bushfire
The risk of bushfires in Fremantle is relatively low compared to other regions in Tasmania, but it's not negligible. Drier conditions and higher temperatures could increase the likelihood of bushfires.
Key drivers:
- ·Increased temperatures
- ·Drier conditions
Heat
Fremantle is likely to experience more frequent and intense heatwaves in the future. This could pose a risk to vulnerable populations, such as the elderly and those with pre-existing health conditions.
Key drivers:
- ·Increased greenhouse gas emissions
- ·Urban heat island effect
Coastal
As a coastal suburb, Fremantle is vulnerable to the impacts of sea level rise and coastal erosion. This could lead to inundation of low-lying areas and damage to infrastructure.
Key drivers:
- ·Sea level rise
- ·Increased storm surge
Wind
Notable wind risk — westerly wind storms
Storm
Moderate storm risk — occasional severe weather
Social
Lower social stability — regional isolation
Energy
Moderate energy costs — winter heating

Learn moreAbout Fremantle's Climate Risk Profile
Fremantle, located in Tasmania, is a suburb that will be increasingly affected by climate change. The primary risks include coastal inundation due to sea level rise, increased flooding from more intense rainfall events, and the potential for more frequent and severe heatwaves. While bushfire risk is relatively lower compared to other regions, it is still a concern that could increase with drier conditions.
The coastal location of Fremantle makes it particularly vulnerable to sea level rise. Low-lying areas are at risk of permanent inundation, and storm surges could cause significant damage to infrastructure and property. The increasing intensity of rainfall events is also a major concern, as it could overwhelm existing drainage systems and lead to widespread flooding.
Rising temperatures will likely lead to more frequent and intense heatwaves, posing a health risk to vulnerable populations. It is crucial for residents to take precautions during these events, such as staying hydrated and seeking shelter in air-conditioned environments. The changing climate may also impact local ecosystems and biodiversity.
To mitigate these risks, it is essential for the community to implement adaptation measures. This includes investing in improved drainage infrastructure, protecting coastal areas with seawalls or other barriers, and developing heatwave response plans. Individual property owners can also take steps to reduce their vulnerability, such as raising the elevation of their homes and installing flood-resistant materials.
