Climate Hazard Breakdown for Kiama Downs
Flood
Kiama Downs faces a moderate risk of flooding due to its proximity to Minnamurra River and low-lying areas. Intense rainfall events can lead to riverine and flash flooding.
Key drivers:
- ·Increased rainfall intensity
- ·Sea level rise
Bushfire
The risk of bushfire in Kiama Downs is moderate, with some areas bordering bushland. Hot, dry conditions and strong winds can increase the likelihood of fire.
Key drivers:
- ·Increased frequency of heatwaves
- ·Drier vegetation
Heat
Kiama Downs is likely to experience more frequent and intense heatwaves. This poses a risk to vulnerable populations, such as the elderly and those with chronic health conditions.
Key drivers:
- ·Rising global temperatures
- ·Urban heat island effect
Coastal
Kiama Downs faces a moderate risk from coastal hazards, including sea level rise and coastal erosion. Low-lying areas are particularly vulnerable.
Key drivers:
- ·Sea level rise
- ·Increased storm intensity

What This Means for Property Owners
Insurance Outlook
Insurance premiums are likely to increase in the future due to the increased risk of flooding, bushfire, and coastal erosion.
Price Impact
Properties in high-risk areas may experience a decrease in value due to climate change impacts.
Buyer Checklist
- 1.Check flood maps and bushfire prone land maps.
- 2.Assess the property's vulnerability to coastal erosion.
- 3.Inquire about the property's insurance history.
- 4.Consider the long-term climate change risks.
How the region's climate is projected to change
Regional projections, not a forecast for this street. Figures are from the WA Department of Water and Environmental Regulation's climate projections for the South Western Flatlands region, which draws on CSIRO and Bureau of Meteorology modelling.
Temperature
+0.5 to 1.1°C by 2030
Above the 1986–2005 climate, on all emissions scenarios. By 2090, 1.2 to 2.0°C under intermediate emissions or 2.6 to 4.0°C under high emissions.
Rainfall
Winter rain down up to 15% by 2030
The South West has been drying since 1970, and the decline has been larger than anywhere else in Australia. Heavy rainfall events are projected to become more intense even as totals fall.
Fire weather
Harsher, magnitude uncertain
High confidence that fire weather becomes harsher, low confidence in the size of the change, because it depends heavily on summer rainfall.
Sea level
+0.12 m by 2030
At the Fremantle gauge, range 0.07 to 0.16 m. Very high confidence that sea levels continue to rise through the century.

Learn moreAbout Kiama Downs's Climate Risk Profile
Kiama Downs, located on the NSW South Coast, is increasingly vulnerable to the impacts of climate change. The suburb's proximity to the coast and the Minnamurra River makes it susceptible to flooding and coastal erosion. Rising temperatures are also a significant concern, with more frequent and intense heatwaves expected in the future.
The risk of flooding is driven by increased rainfall intensity and sea level rise. Intense rainfall events can cause the Minnamurra River to overflow, inundating low-lying areas. Sea level rise exacerbates the problem by reducing the capacity of the river to drain and increasing the risk of coastal inundation.
Bushfire risk is also a concern, particularly in areas bordering bushland. Hot, dry conditions and strong winds can create ideal conditions for bushfires to spread rapidly. Residents should be aware of the risks and take steps to prepare their properties.
Heatwaves are becoming more frequent and intense, posing a significant risk to vulnerable populations. The elderly, those with chronic health conditions, and those who work outdoors are particularly at risk. Residents should take steps to stay cool during heatwaves, such as drinking plenty of water, staying indoors, and using air conditioning.
Coastal erosion is another significant threat, with sea level rise and increased storm intensity contributing to the problem. Low-lying areas are particularly vulnerable, and residents should be aware of the risks and take steps to protect their properties.
