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 North Mackay.

North Mackay (postcode 4740) 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 (11.5% of land in high-risk zones), tropical cyclone (11.2% of land in high-risk zones), surface flood (8.3% of land in high-risk zones).
