Hazard Breakdown
Climate Hazard Breakdown for Battery Point
Flood
Battery Point faces a moderate risk of flooding, primarily from heavy rainfall and potential coastal inundation. The area's proximity to the Derwent River increases its vulnerability.
Key drivers:
- ·Increased rainfall intensity
- ·Sea level rise
Bushfire
Bushfire risk in Battery Point is relatively low due to its urban setting and limited vegetation. However, ember attack from distant fires remains a potential concern.
Key drivers:
- ·Proximity to bushland
- ·Dry vegetation
Heat
Battery Point experiences moderate heat risk, with increasing average temperatures and potential for heatwaves. Urban heat island effect can exacerbate conditions.
Key drivers:
- ·Rising average temperatures
- ·Increased frequency of heatwaves
Coastal
Battery Point is exposed to coastal risks, including sea level rise and erosion. Low-lying areas are particularly vulnerable to inundation during storm events.
Key drivers:
- ·Sea level rise
- ·Increased storm intensity
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

Historical Climate Events
The 1967 Tasmanian bushfires impacted areas near Hobart, causing significant damage and loss of life. While Battery Point was not directly affected, smoke and ash impacted the suburb.
SourceA severe storm caused flash flooding and power outages in Hobart, including Battery Point. Heavy rainfall overwhelmed drainage systems, leading to localized flooding.
SourceHobart experienced a prolonged heatwave in January 2020, with temperatures exceeding 35°C for several days. This put strain on infrastructure and increased demand for cooling.
SourceHeavy rainfall caused minor flooding in low-lying areas of Battery Point. Some roads were temporarily closed, and some properties experienced water damage.

Learn moreAbout Battery Point's Climate Risk Profile
Battery Point, a historic suburb of Hobart, Tasmania, is increasingly vulnerable to the impacts of climate change. The suburb's coastal location and low-lying areas make it particularly susceptible to flooding and sea level rise.
Rising average temperatures and more frequent heatwaves pose a growing threat to public health, especially for vulnerable populations. The urban heat island effect can exacerbate these conditions, leading to increased energy consumption and strain on infrastructure.
Changes in rainfall patterns, including more intense rainfall events, can lead to increased flooding risk. This can damage property, disrupt transportation, and pose a threat to public safety. Coastal erosion is also a concern, as rising sea levels and storm surges can erode shorelines and damage coastal infrastructure.
Addressing these climate risks requires a coordinated effort from government, businesses, and residents. Implementing adaptation measures, such as improving drainage infrastructure, protecting coastal areas, and promoting energy efficiency, can help reduce the suburb's vulnerability to climate change. Mitigation efforts, such as reducing greenhouse gas emissions, are also essential to slow the pace of climate change and protect Battery Point for future generations.
