Australia Climate Risk Map
The Climate Council Australia Climate Risk Map is an interactive map of climate-vulnerable places in Australia. Enter your suburb or postcode in the search bar in the upper right corner of the map below to understand the risks in your area.
How to use the climate risk map [click here to expand]
This map allows you to visualize the percentage of properties in your suburb, local government area, or federal electorate that are at medium to high risk* of climate impacts. To start:
- Enter your suburb or postal code in the search bar in the upper right corner of the map.
- Click on your suburb, or surrounding suburbs, to see how they will be affected by climate change and the number of at-risk properties in your area.
- Scroll down and switch between low, medium, and high emissions scenarios, as well as different time frames, geographies, and hazards to understand how climate action, or lack thereof, will impact the number of homes in your community at risk of climatic impacts.

FAQ – Answers to your questions
*What is a medium or high risk house?
High risk houses have annual damage costs from climate change and extreme weather equivalent to 1% or more of the replacement cost of the property. These properties are effectively uninsurable, because – although policies may still be offered by some insurance companies – insurance premiums are expected to become too expensive for people, making insurance inaccessible.
Medium risk properties have annual damage costs equivalent to 0.2-1% of the replacement cost of the property. These properties are at risk of being underinsured.
What do the different emission scenarios mean?
The map allows you to explore extreme weather impacts under three different emission scenarios. These scenarios are based on the “Representative Concentration Pathways” or “RCPs” used by the Intergovernmental Panel on Climate Change. The low, medium and high scenarios correspond respectively to RCPs 2.6, 4.5 and 8.5.
Low: This scenario shows extreme weather impacts in a scenario where global emissions are significantly reduced. This scenario would likely limit global average temperature rise to about 1.8ºC in 2100. (Available data did not allow us to model a scenario that would see global average temperature rise limited to 1.5ºC.)
Medium: This scenario shows extreme weather impacts in a scenario in which all countries implement their existing emission reduction policies, resulting in a likely increase in global average temperature of about 2.7ºC by 2100.
High: This scenario shows extreme weather impacts in a high emissions scenario, in which the world flatly fails to address the climate crisis. This corresponds to a likely temperature range of about 4.4°C by 2100.
How are the different hazards defined?
The map covers five hazards exacerbated by climate change: riverine flooding, surface water flooding, coastal flooding, bush fires and extreme winds. Definitions of each of these hazards are provided below:
- River floods it is when a river exceeds its capacity, flooding nearby areas.
- Coastal flooding occurs when seawater temporarily or permanently inundates an area due to a combination of sea level rise, high tides, wind, low atmospheric pressure and/or waves. This definition does not include coastal erosion. In a high emissions scenario, these data assume a sea level rise of 1.5 m by 2100.
- extreme wind are strong wind conditions that can exceed a building’s design specifications (due to expected changes in sea surface temperature, wind regimes and speeds).
- Bush fires are destructive fires that spread through trees and forest. This definition does not include grass fires.
- Surface water flooding (sometimes called storm floods or flash floods) are surface floods. This occurs when sustained rains or heavy rainfall of short duration cause the soil to reach saturation point and drainage systems to overflow, causing excess water to accumulate.
