Flood Risk Analysis

Coombell, 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 Coombell 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.

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.

Coombell sits within ClimateNest's suburb-level hazard model for flood risk. 2.9% of the suburb's land area is mapped in high-risk flood zones and 79% 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 Coombell.

On ClimateNest's 0–10 suburb hazard index, Coombell scores 2 for flood risk — a lower exposure relative to the Australian suburb range. For comparison, properties in Coombell can still sit well above or below this suburb average depending on elevation, distance to waterways or vegetation, and local drainage.

Coombell located in Regional SA (postcode 5267), is a South Australia suburb tracked by ClimateNest. The suburb's median property value is $375,000, and understanding climate exposure is becoming a standard part of due diligence for buyers, lenders and insurers pricing property in Coombell.

Across the six hazard axes ClimateNest models, the dominant climate risk in Coombell is extreme heat (score 6/10), with moderate exposure. Insurance signals for the suburb point to premiums rising moderately (+25% by 2030). These suburb-level signals help prioritise which properties need the closest look — the actual risk of any single home can only be confirmed with an address-level report.

Whether you are buying, selling or renovating in Coombell, extreme heat is the hazard to weigh first. Local council planning controls, state hazard mapping and lender climate policies each reference this kind of suburb-level signal, and property decisions in Coombell are increasingly made with an address-level climate report in hand.
