Hazard Breakdown
Climate Hazard Breakdown for Porepunkah
Flood
Porepunkah faces a moderate risk of flooding due to its proximity to the Ovens River and other waterways. Heavy rainfall events can lead to riverine flooding, impacting low-lying areas and properties near the riverbanks.
Key drivers:
- ·Increased rainfall intensity
- ·Climate change
Bushfire
Porepunkah is located in a bushfire-prone region. The surrounding forests and grasslands pose a significant bushfire risk during the dry summer months. Hot, dry, and windy conditions can exacerbate the risk.
Key drivers:
- ·Increased temperatures
- ·Drier conditions
Heat
Porepunkah experiences moderate heat risk, with increasing average temperatures and more frequent heatwaves projected. This can impact vulnerable populations and increase energy demand for cooling.
Key drivers:
- ·Climate change
- ·Urban heat island effect
Coastal
Porepunkah is not located near the coast and therefore has a negligible risk associated with coastal hazards such as sea level rise and coastal erosion.
Wind
Moderate wind risk — cold fronts and gusty winds
Storm
Moderate storm risk — severe thunderstorms
Social
Moderate social stability
Energy
Moderate energy costs — heating and cooling needs

Learn moreAbout Porepunkah's Climate Risk Profile
Porepunkah, located in northeastern Victoria, is susceptible to a range of climate-related risks. The most significant threats are flooding from the Ovens River and bushfires due to the surrounding forested areas. Climate change is expected to exacerbate these risks, leading to more frequent and intense extreme weather events.
The risk of flooding in Porepunkah is primarily driven by heavy rainfall events that cause the Ovens River to overflow its banks. The low-lying areas near the river are particularly vulnerable. Climate change projections indicate an increase in rainfall intensity, which will likely increase the frequency and severity of flooding events.
Bushfire risk is also a major concern for Porepunkah. The surrounding forests provide ample fuel for bushfires, and hot, dry, and windy conditions can quickly escalate the risk. Climate change is expected to increase the frequency and severity of bushfires in the region, posing a significant threat to life and property.
Heatwaves are becoming more frequent and intense in Porepunkah, posing a risk to vulnerable populations such as the elderly and those with chronic health conditions. Climate change is driving this trend, and residents should take steps to prepare for extreme heat events.
While Porepunkah is not directly exposed to coastal risks, the broader impacts of climate change, such as disruptions to supply chains and increased migration, could indirectly affect the community.
