Kununurra sits within ClimateNest's suburb-level hazard model for flood risk. 6.5% of the suburb's land area is mapped in high-risk flood zones and 74.3% 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 Kununurra.
Kununurra (postcode 6743) 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 bushfire (21.5% of land in high-risk zones), riverine flood (6.5% of land in high-risk zones), surface flood (6.4% of land in high-risk zones). Exposure is not uniform across Kununurra โ individual properties can sit well above or below these averages, so an address-level check is recommended before buying, selling or insuring.
