Key Facts

Climate Safety
Medium
Flood
Collaroy faces a moderate risk of flooding, primarily from heavy rainfall and coastal inundation. The area has a history of flooding events, and climate change is expected to increase the frequency and intensity of these events.
Bushfire
Collaroy has a relatively low bushfire risk due to its coastal location and urban development. However, areas adjacent to bushland reserves are still susceptible to ember attack and potential fire spread during extreme conditions.
Heat
Collaroy is experiencing increasing heatwave intensity and frequency. Rising average temperatures pose health risks, especially for vulnerable populations. Urban areas within Collaroy are prone to the urban heat island effect.
Storm
Notable storm risk — tropical cyclones and severe thunderstorms in summer months
Postcode
4707
Highest high-risk exposure
15.6% of land (tropical cyclone)

Climate Safety Analysis

Collaroy in Queensland has an overall climate safety rating of Medium. This multi-hazard assessment combines flood, bushfire, heat, coastal, and storm risk data with climate projections to 2050 from CSIRO and the Bureau of Meteorology.

Key factors affecting Collaroy's climate safety include heat, flood, coastal. Each hazard is assessed independently and combined for an overall picture. Australia has warmed by approximately 1.5 °C since 1910, with flow-on effects to fire weather, extreme rainfall, and heatwave frequency.

Climate safety for property in Collaroy is not uniform — it varies by address. Factors such as elevation, distance to waterways, proximity to bushland, and local drainage all influence actual risk at a specific property. Two nearby properties can have materially different risk profiles.

For a complete property-specific climate safety report for Collaroy including address-level hazard mapping, insurance outlook, and adaptation recommendations, use the ClimateNest full analysis tool.

Collaroy (postcode 4707) is tracked in ClimateNest's suburb hazard model, which maps the share of the suburb's land exposed to each hazard at high and moderate levels. The suburb's highest high-risk exposures are tropical cyclone (15.6% of land in high-risk zones), riverine flood (14.7% of land in high-risk zones), bushfire (13.3% of land in high-risk zones). Exposure is not uniform across Collaroy — individual properties can sit well above or below these averages, so an address-level check is recommended before buying, selling or insuring.
