Coogee sits within ClimateNest's suburb-level hazard model for flood risk. 6.3% of the suburb's land area is mapped in high-risk flood zones and 78.8% 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 Coogee.
On ClimateNest's 0–10 suburb hazard index, Coogee scores 3 for flood risk — a lower exposure relative to the Australian suburb range. For comparison, properties in Coogee can still sit well above or below this suburb average depending on elevation, distance to waterways or vegetation, and local drainage.
Coogee located in Greater Sydney (postcode 2034), is a New South Wales suburb tracked by ClimateNest. The suburb's median property value is $1.6 million, and understanding climate exposure is becoming a standard part of due diligence for buyers, lenders and insurers pricing property in Coogee.
Across the six hazard axes ClimateNest models, the dominant climate risk in Coogee is extreme heat (score 5/10), with moderate exposure. Insurance signals for the suburb point to premiums rising moderately (+20% by 2030).

Insurance costs for flood cover in Coogee 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 Coogee?
Yes, flood risk can affect property values in Coogee. 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 Coogee?
Elevation is a critical factor in flood risk. Properties at higher elevations within Coogee 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 Coogee?
ClimateNest's suburb model rates Coogee's dominant climate risk as extreme heat at 5/10 on a 0–10 index, followed by damaging wind (4/10) and severe storm (4/10). These are suburb-level averages — an address-level report is needed to confirm the risk of a specific property in Coogee.
What share of Coogee is exposed to high bushfire risk?
ClimateNest's hazard overlay maps 13.7% of Coogee in high-risk zones for bushfire, with a further 62.1% in moderate-risk zones. Suburb-level exposure is not uniform — individual properties can differ from these averages, so an address-level check is recommended.
