Flood Risk Analysis

Buttaba, located in New South Wales, has a notable flood risk profile based on available data including proximity to waterways, elevation, and historical flood events. The Bureau of Meteorology (BOM) maintains river height and flood warning data for catchments across New South Wales.

Historical flood data indicates that properties close to the lake are most vulnerable.

Buttaba faces a moderate risk of flooding due to its proximity to waterways and low-lying areas. Climate change is expected to increase rainfall intensity, exacerbating flood risk.

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.

Buttaba sits within ClimateNest's suburb-level hazard model for flood risk. 4.1% of the suburb's land area is mapped in high-risk flood zones and 72.1% 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 Buttaba.

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

Buttaba located in Coastal NSW (postcode 2283), 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 Buttaba.

Across the six hazard axes ClimateNest models, the dominant climate risk in Buttaba is extreme heat (score 5/10), with moderate exposure. Insurance signals for the suburb point to premiums rising moderately (+30% by 2030). These suburb-level signals help prioritise which properties need the closest look — the actual risk of any single home can only be confirmed with an address-level report.

Whether you are buying, selling or renovating in Buttaba, extreme heat is the hazard to weigh first. Local council planning controls, state hazard mapping and lender climate policies each reference this kind of suburb-level signal, and property decisions in Buttaba are increasingly made with an address-level climate report in hand.

Frequently Asked Questions

Is Buttaba at risk of flooding?

Based on available data, Buttaba has a notable flood risk profile. Flood risk varies by address — check your specific property for precise flood zone mapping and elevation data with ClimateNest.

What flood insurance costs can I expect in Buttaba?

Insurance costs for flood cover in Buttaba depend on the property's flood zone classification, elevation, and proximity to waterways. ClimateNest provides address-level insurance cost estimates based on your property's specific hazard exposure.

Does flood risk affect property values in Buttaba?

Yes, flood risk can affect property values in Buttaba. Properties in mapped flood zones may experience lower buyer demand, reduced valuations, and higher insurance costs. Lenders increasingly assess flood exposure as part of mortgage risk evaluation.

How does elevation affect flood risk in Buttaba?

Elevation is a critical factor in flood risk. Properties at higher elevations within Buttaba typically have lower flood exposure than those near waterways or in low-lying areas. Address-level elevation data combined with BOM flood mapping provides the most accurate picture.

What are the main climate risks in Buttaba?

ClimateNest's suburb model rates Buttaba's dominant climate risk as extreme heat at 5/10 on a 0–10 index, followed by damaging wind (5/10) and severe storm (5/10). These are suburb-level averages — an address-level report is needed to confirm the risk of a specific property in Buttaba.

What share of Buttaba is exposed to high bushfire risk?

ClimateNest's hazard overlay maps 11.3% of Buttaba in high-risk zones for bushfire, with a further 74.4% in moderate-risk zones. Suburb-level exposure is not uniform — individual properties can differ from these averages, so an address-level check is recommended.
