Flood Risk in Goolwa South, SA: 2026 Assessment

Goolwa South, located in South Australia, 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 South Australia.

Low-lying areas near the river and coast are most vulnerable.

Goolwa South faces a moderate risk of flooding due to its proximity to the coast and the Murray River estuary. Sea level rise and increased rainfall intensity could exacerbate this 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.

Goolwa South sits within ClimateNest's suburb-level hazard model for flood risk. 3.6% 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 Goolwa South.

Goolwa South (postcode 5214) 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 (11.6% of land in high-risk zones), bushfire (6.1% of land in high-risk zones), riverine flood (3.6% of land in high-risk zones). Exposure is not uniform across Goolwa South — individual properties can sit well above or below these averages, so an address-level check is recommended before buying, selling or insuring.
