Hazard Breakdown
Climate Hazard Breakdown for Milsons Passage
Flood
Milsons Passage faces a moderate risk of flooding due to its proximity to waterways and low-lying areas. Increased rainfall intensity and sea-level rise are expected to exacerbate this risk.
Key drivers:
- ·Increased rainfall intensity
- ·Sea-level rise
Bushfire
The bushfire risk in Milsons Passage is moderate due to surrounding vegetation. Hotter, drier conditions are expected to increase the frequency and intensity of bushfires.
Key drivers:
- ·Hotter, drier conditions
- ·Increased fuel load
Heat
Milsons Passage is likely to experience more frequent and intense heatwaves. This poses a risk to vulnerable populations, particularly the elderly and those with pre-existing health conditions.
Key drivers:
- ·Rising average temperatures
- ·Increased frequency of heatwaves
Coastal
Milsons Passage faces a moderate risk from coastal hazards due to sea level rise. This includes potential inundation of low-lying areas and increased erosion.
Key drivers:
- ·Sea-level rise
- ·Increased storm surge
Wind
Moderate wind risk — East Coast Lows and gust fronts
Storm
Moderate storm risk — severe thunderstorms and hail
Social
Moderate social stability — mixed urban density
Energy
Moderate energy costs — climate-driven cooling demand

Learn moreAbout Milsons Passage's Climate Risk Profile
Milsons Passage, located in New South Wales, is susceptible to a range of climate-related hazards. The primary risks include flooding due to its proximity to waterways, bushfires due to surrounding vegetation, and heatwaves during the summer months. Sea-level rise also poses a threat to coastal areas within the suburb.
The risk of flooding is expected to increase with more intense rainfall events and rising sea levels. This could lead to inundation of low-lying areas, damage to property, and disruption to infrastructure. Bushfire risk is also projected to increase due to hotter, drier conditions, which could lead to more frequent and intense fires.
Heatwaves are becoming more common and severe, posing a significant risk to vulnerable populations. The elderly, children, and those with pre-existing health conditions are particularly at risk during extreme heat events. Coastal erosion and inundation are also concerns, especially in areas close to the shoreline.
Addressing these climate risks requires a combination of mitigation and adaptation measures. Mitigation efforts focus on reducing greenhouse gas emissions to slow down the rate of climate change. Adaptation measures focus on preparing for the impacts of climate change that are already locked in, such as building flood defenses, managing vegetation to reduce bushfire risk, and implementing heatwave early warning systems.
