Flood Risk in Blackwall, TAS: 2026 Assessment

Blackwall, located in Tasmania, 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 Tasmania.

Flood risk in Blackwall 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.

Moderate flood risk — riverine flooding in catchment areas

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.

Blackwall sits within ClimateNest's suburb-level hazard model for flood risk. 3.8% of the suburb's land area is mapped in high-risk flood zones and 79.7% 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 Blackwall.

Blackwall (postcode 7275) 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 extreme wind (7.9% of land in high-risk zones), bushfire (7.2% of land in high-risk zones), riverine flood (3.8% of land in high-risk zones). Exposure is not uniform across Blackwall — individual properties can sit well above or below these averages, so an address-level check is recommended before buying, selling or insuring.
