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.
The Gap sits within ClimateNest's suburb-level hazard model for flood risk. 7.7% of the suburb's land area is mapped in high-risk flood zones and 66.7% 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 The Gap.
The Gap (postcode 4061) 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 (12.3% of land in high-risk zones), extreme wind (9.5% of land in high-risk zones), riverine flood (7.7% of land in high-risk zones). Exposure is not uniform across The Gap โ individual properties can sit well above or below these averages, so an address-level check is recommended before buying, selling or insuring.

How does elevation affect flood risk in The Gap?
Elevation is a critical factor in flood risk. Properties at higher elevations within The Gap typically have lower flood exposure than those near waterways or in low-lying areas. Address-level elevation data combined with BOM flood mapping provides the most accurate picture.
What share of The Gap is exposed to high bushfire risk?
ClimateNest's hazard overlay maps 12.3% of The Gap in high-risk zones for bushfire, with a further 82% in moderate-risk zones. Suburb-level exposure is not uniform โ individual properties can differ from these averages, so an address-level check is recommended.
