Flood Risk in East Devonport, TAS: 2026 Assessment

East Devonport, located in Tasmania, 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 Tasmania.

The Mersey River has a history of flooding in the Devonport area. Recent infrastructure upgrades have aimed to mitigate some of this risk.

East Devonport faces a moderate risk of flooding due to its proximity to the Mersey River and low-lying areas. Increased rainfall intensity and rising sea levels 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.

East Devonport sits within ClimateNest's suburb-level hazard model for flood risk. 8.8% of the suburb's land area is mapped in high-risk flood zones and 66.1% 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 East Devonport.

East Devonport (postcode 7310) 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 riverine flood (8.8% of land in high-risk zones), extreme wind (6.3% of land in high-risk zones), surface flood (5.4% of land in high-risk zones). Exposure is not uniform across East Devonport — individual properties can sit well above or below these averages, so an address-level check is recommended before buying, selling or insuring.
