Flood Risk in Port Pirie, SA: 2026 Assessment

Port Pirie, 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 coast are most vulnerable to flooding.

Port Pirie faces a moderate risk of flooding due to its low-lying coastal location and proximity to waterways. Increased rainfall intensity and sea level rise are expected to 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.

Port Pirie sits within ClimateNest's suburb-level hazard model for flood risk. 1.8% of the suburb's land area is mapped in high-risk flood zones and 76.6% 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 Port Pirie.

Port Pirie (postcode 5540) 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 bushfire (15.2% of land in high-risk zones), extreme wind (5.8% of land in high-risk zones), surface flood (5.1% of land in high-risk zones). Exposure is not uniform across Port Pirie — individual properties can sit well above or below these averages, so an address-level check is recommended before buying, selling or insuring.
