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 Blackwood.
Blackwood (postcode 3458) 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 surface flood (8.6% of land in high-risk zones), bushfire (6.5% of land in high-risk zones), riverine flood (3.8% of land in high-risk zones).
