Flood Risk in Cadgee, SA: 2026 Assessment

Cadgee, located in South Australia, has a moderate 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 South Australia.

Flood risk in Cadgee is shaped by local topography and catchment characteristics. Even within a single suburb, elevation differences can significantly change flood exposure. Properties near waterways or in low-lying areas warrant closer assessment.

Lower flood risk — localised flooding during heavy rain events

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.

Cadgee sits within ClimateNest's suburb-level hazard model for flood risk. 3.2% of the suburb's land area is mapped in high-risk flood zones and 73.9% 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 Cadgee.

Cadgee (postcode 5271) 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 (11.1% of land in high-risk zones), bushfire (11% of land in high-risk zones), extreme wind (3.8% of land in high-risk zones). Exposure is not uniform across Cadgee — individual properties can sit well above or below these averages, so an address-level check is recommended before buying, selling or insuring.
