Flood Risk in St Johns Park, SA: 2026 Assessment

St Johns Park, 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 St Johns Park 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.

St Johns Park sits within ClimateNest's suburb-level hazard model for flood risk. 3.4% of the suburb's land area is mapped in high-risk flood zones and 88.1% 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 St Johns Park.

St Johns Park (postcode 5373) 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 (12.6% of land in high-risk zones), surface flood (4.8% of land in high-risk zones), riverine flood (3.4% of land in high-risk zones). Exposure is not uniform across St Johns Park — individual properties can sit well above or below these averages, so an address-level check is recommended before buying, selling or insuring.
