Flood Risk in South Coogee, NSW: 2026 Assessment

South Coogee, 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.

Low-lying areas near the coast are most vulnerable to flooding.

South Coogee faces a moderate risk of flooding, primarily from heavy rainfall events and coastal inundation. The risk is exacerbated by the suburb's proximity to the coast and low-lying areas.

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.

South Coogee sits within ClimateNest's suburb-level hazard model for flood risk. 4.4% of the suburb's land area is mapped in high-risk flood zones and 83.8% 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 South Coogee.

South Coogee (postcode 2034) 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 coastal inundation (9% of land in high-risk zones), bushfire (8.2% of land in high-risk zones), extreme wind (4.7% of land in high-risk zones). Exposure is not uniform across South Coogee — individual properties can sit well above or below these averages, so an address-level check is recommended before buying, selling or insuring.
