Canley Heights sits within ClimateNest's suburb-level hazard model for flood risk. 8.1% of the suburb's land area is mapped in high-risk flood zones and 68% in moderate-risk zones, based on the national hazard overlay. Exposure at this scale varies street by street, which is why an address-level check matters before you buy or insure a specific property in Canley Heights.

On ClimateNest's 0–10 suburb hazard index, Canley Heights scores 3 for flood risk — a lower exposure relative to the Australian suburb range. For comparison, properties in Canley Heights can still sit well above or below this suburb average depending on elevation, distance to waterways or vegetation, and local drainage.
