Flood Risk Analysis

Rennie, 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.

Rennie's proximity to the Murray River increases its susceptibility to riverine flooding during periods of heavy rainfall and high river levels.

Rennie faces a moderate risk of flooding, primarily from heavy rainfall events and nearby waterways. The risk is expected to increase due to climate change.

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.

Rennie sits within ClimateNest's suburb-level hazard model for flood risk. 11% of the suburb's land area is mapped in high-risk flood zones and 59.8% 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 Rennie.

Rennie (postcode 2646) 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 riverine flood (11% of land in high-risk zones), surface flood (6.5% of land in high-risk zones), bushfire (5% of land in high-risk zones). Exposure is not uniform across Rennie — individual properties can sit well above or below these averages, so an address-level check is recommended before buying, selling or insuring.

Based on available data, Rennie has a notable flood risk profile. Flood risk varies by address — check your specific property for precise flood zone mapping and elevation data with ClimateNest.

What flood insurance costs can I expect in Rennie?

Insurance costs for flood cover in Rennie depend on the property's flood zone classification, elevation, and proximity to waterways. ClimateNest provides address-level insurance cost estimates based on your property's specific hazard exposure.

Does flood risk affect property values in Rennie?
