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 Collaroy Plateau
Flood
Collaroy Plateau faces a moderate risk of flooding, primarily from heavy rainfall events and localised stormwater runoff. The risk is influenced by the suburb's topography and proximity to drainage systems.
Key drivers:
- ·Increased rainfall intensity
- ·Urban development
Bushfire
Collaroy Plateau has a high bushfire risk due to its proximity to Garigal National Park and other areas of dense vegetation. Hot, dry summers and strong winds exacerbate the risk.
Key drivers:
- ·Dry vegetation
- ·High temperatures
Heat
Collaroy Plateau experiences moderate heat risk, with increasing average temperatures and more frequent heatwaves projected. This poses a risk to vulnerable populations.
Key drivers:
- ·Rising global temperatures
- ·Urban heat island effect
Coastal
Collaroy Plateau faces a moderate coastal risk due to potential sea level rise and storm surges impacting nearby coastal areas. While the suburb itself is elevated, access routes and infrastructure could be affected.
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 Collaroy Plateau's Climate Risk Profile
Collaroy Plateau, located on the Northern Beaches of Sydney, is exposed to a range of climate-related risks. The suburb's proximity to bushland increases its vulnerability to bushfires, particularly during hot and dry summer months. Climate change is projected to increase the frequency and intensity of bushfire events, posing a significant threat to properties and residents.
Flooding is another concern for Collaroy Plateau, with heavy rainfall events leading to localised flooding and stormwater runoff. The suburb's topography and drainage systems contribute to the flood risk, which is expected to worsen with climate change due to increased rainfall intensity.
Heatwaves are becoming more frequent and intense in Collaroy Plateau, posing a risk to vulnerable populations such as the elderly and those with pre-existing health conditions. Rising average temperatures and the urban heat island effect contribute to the heat risk, which is projected to increase further with climate change.
While Collaroy Plateau is elevated, sea level rise and storm surges could impact nearby coastal areas and infrastructure, potentially affecting access routes and services. Coastal erosion is also a concern for the broader Northern Beaches region, which could indirectly impact Collaroy Plateau.
Addressing these climate risks requires a combination of mitigation and adaptation measures. Reducing greenhouse gas emissions is crucial to slow down the pace of climate change, while adaptation strategies such as improving drainage infrastructure, managing bushfire risk, and implementing heatwave response plans are essential to protect the community.
Suburb pages describe the local picture. The address-level assessment, with its data sources and its dollar projections, is in the ClimateNest report.
