Overall Risk Score
Hazard Breakdown
Flood, bushfire, heat, coastal and storm exposure are all assessed in this area. The score that matters is the property's own: a ClimateNest report scores the address across eight hazards, with insurance and value projections to 2050.
Climate Hazard Breakdown for Brightwaters
Flood
Brightwaters faces a moderate risk of flooding due to its proximity to waterways and low-lying areas. Climate change is expected to increase rainfall intensity, exacerbating flood risk.
Key drivers:
- ·Increased rainfall intensity
- ·Sea level rise
Bushfire
The bushfire risk in Brightwaters is moderate. While not immediately adjacent to dense bushland, the surrounding areas are susceptible to bushfires, and embers can travel long distances.
Key drivers:
- ·Dry vegetation
- ·High temperatures
Heat
Brightwaters 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
Brightwaters faces a moderate risk from coastal hazards due to sea level rise. This includes potential inundation of low-lying areas and increased coastal erosion.
Key drivers:
- ·Sea level rise
- ·Increased storm intensity

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 Brightwaters's Climate Risk Profile
Brightwaters, NSW, is a suburb that will be increasingly affected by climate change. The primary risks are flooding due to increased rainfall intensity and sea level rise, more frequent and intense heatwaves, and a moderate risk of bushfires.
The risk of flooding is driven by the suburb's proximity to waterways and low-lying areas. Climate change is projected to increase rainfall intensity, leading to more frequent and severe flooding events. Sea level rise will also exacerbate the risk of coastal inundation.
Heatwaves are expected to become more frequent and intense, posing a significant risk to vulnerable populations. The urban heat island effect may further amplify temperatures in built-up areas.
While the bushfire risk is moderate, it is important to remain vigilant, especially during dry periods. Embers can travel long distances, and even areas not directly adjacent to bushland can be at risk.
Residents should take steps to prepare for these challenges, such as developing emergency plans, maintaining their properties, and staying informed about weather conditions and warnings.
