Flood Risk Analysis

Thorpdale South, located in Victoria, 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 Victoria.

The Tarwin River and its tributaries can cause localized flooding, particularly after intense rainfall events. The flatter terrain in some areas increases susceptibility.

Moderate flood risk due to proximity to waterways and historical rainfall patterns.

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.

Thorpdale South sits within ClimateNest's suburb-level hazard model for flood risk. 5.6% of the suburb's land area is mapped in high-risk flood zones and 77.7% 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 Thorpdale South.

Thorpdale South (postcode 3824) 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 (16.9% of land in high-risk zones), riverine flood (5.6% of land in high-risk zones), extreme wind (4% of land in high-risk zones). Exposure is not uniform across Thorpdale South โ€” individual properties can sit well above or below these averages, so an address-level check is recommended before buying, selling or insuring.
