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 Middle Swan.

Middle Swan (postcode 6056) 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 (5.9% of land in high-risk zones), bushfire (5.9% of land in high-risk zones), tropical cyclone (5.5% of land in high-risk zones). Exposure is not uniform across Middle Swan — individual properties can sit well above or below these averages, so an address-level check is recommended before buying, selling or insuring.
