Port Pirie West (postcode 5540) 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 (17.6% of land in high-risk zones), extreme wind (4% of land in high-risk zones), surface flood (3.4% of land in high-risk zones). Exposure is not uniform across Port Pirie West — individual properties can sit well above or below these averages, so an address-level check is recommended before buying, selling or insuring.
