Brombin sits within ClimateNest's suburb-level hazard model for flood risk. 6.6% of the suburb's land area is mapped in high-risk flood zones and 71% 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 Brombin.

On ClimateNest's 0–10 suburb hazard index, Brombin scores 4 for flood risk — a moderate exposure relative to the Australian suburb range. For comparison, properties in Brombin can still sit well above or below this suburb average depending on elevation, distance to waterways or vegetation, and local drainage.

Brombin located in Coastal NSW (postcode 2446), is a New South Wales suburb tracked by ClimateNest. The suburb's median property value is $925,000, and understanding climate exposure is becoming a standard part of due diligence for buyers, lenders and insurers pricing property in Brombin.

What share of Brombin is exposed to high bushfire risk?

ClimateNest's hazard overlay maps 13.2% of Brombin in high-risk zones for bushfire, with a further 72.4% in moderate-risk zones. Suburb-level exposure is not uniform — individual properties can differ from these averages, so an address-level check is recommended.
