Fernances faces a moderate risk of flooding, primarily from heavy rainfall events and nearby waterways. Properties in low-lying areas are particularly vulnerable.

For a comprehensive property-specific flood assessment including address-level elevation data, flood overlay mapping, and insurance cost estimates, use the ClimateNest full analysis tool. General suburb data cannot replace a site-specific evaluation.

Fernances sits within ClimateNest's suburb-level hazard model for flood risk. 5.4% of the suburb's land area is mapped in high-risk flood zones and 77.4% 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 Fernances.

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

Fernances located in Coastal NSW (postcode 2775), 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 Fernances.

Across the six hazard axes ClimateNest models, the dominant climate risk in Fernances is extreme heat (score 5/10), with moderate exposure. Insurance signals for the suburb point to premiums rising moderately (+30% by 2030).

What share of Fernances is exposed to high bushfire risk?

ClimateNest's hazard overlay maps 14.5% of Fernances in high-risk zones for bushfire, with a further 58.1% in moderate-risk zones. Suburb-level exposure is not uniform — individual properties can differ from these averages, so an address-level check is recommended.
