Flood Risk in Kyeemagh, NSW: 2026 Assessment

Kyeemagh, located in New South Wales, has a notable flood risk profile based on available data including proximity to waterways, elevation, and historical flood events. The Bureau of Meteorology (BOM) maintains river height and flood warning data for catchments across New South Wales.

Kyeemagh has experienced several flooding events in the past, particularly along the Cooks River. The council has implemented some flood mitigation measures, but further upgrades may be necessary to address increasing risks.

Kyeemagh is located near Botany Bay and Cooks River, making it susceptible to flooding from heavy rainfall and storm surges. Climate change is expected to increase the frequency and intensity of extreme rainfall events, exacerbating flood risk.

For a comprehensive property-specific flood assessment including address-level elevation data, flood overlay mapping, and insurance cost estimates, use the ClimateNest full analysis tool. General suburb data cannot replace a site-specific evaluation.

Kyeemagh sits within ClimateNest's suburb-level hazard model for flood risk. 6.4% of the suburb's land area is mapped in high-risk flood zones and 66.1% 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 Kyeemagh.

Kyeemagh (postcode 2216) 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 surface flood (12.4% of land in high-risk zones), bushfire (9.9% of land in high-risk zones), riverine flood (6.4% of land in high-risk zones). Exposure is not uniform across Kyeemagh — individual properties can sit well above or below these averages, so an address-level check is recommended before buying, selling or insuring.
