Flood Risk Analysis

Bongaree, located in Queensland, 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 Queensland.

Bongaree's low elevation makes it susceptible to tidal inundation and storm surge.

Bongaree faces a moderate risk of flooding due to its low-lying coastal location and proximity to waterways. Intense rainfall events can lead to stormwater and riverine flooding.

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.

Bongaree sits within ClimateNest's suburb-level hazard model for flood risk. 15.4% of the suburb's land area is mapped in high-risk flood zones and 74.5% 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 Bongaree.

On ClimateNest's 0–10 suburb hazard index, Bongaree scores 5 for flood risk — a moderate exposure relative to the Australian suburb range. For comparison, properties in Bongaree can still sit well above or below this suburb average depending on elevation, distance to waterways or vegetation, and local drainage.
