- Blackwall has a relatively low bushfire risk due to its location and limited surrounding bushland. However, increased temperatures and drier conditions could elevate the risk in the future.
- Heat
- Blackwall is likely to experience more frequent and intense heatwaves due to climate change. This poses a risk to vulnerable populations, such as the elderly and those with chronic health conditions.
- Storm
- Moderate storm risk — East Coast Lows bring severe weather including hail and damaging winds
- Postcode
- 2256
- Region
- Coastal NSW
- Median property value
- $925,000

Which climate hazard poses the biggest risk in Blackwall?
The dominant hazard for Blackwall depends on geography and local environment. Proximity to waterways elevates flood risk, while proximity to bushland increases bushfire risk. ClimateNest's multi-hazard analysis identifies the highest-risk hazards for any specific address.
How does Blackwall compare to nearby suburbs for climate safety?
Nearby suburbs may have different climate risk profiles depending on elevation, vegetation cover, drainage patterns, and land use. ClimateNest allows comparison of climate safety scores across New South Wales suburbs.
Should I be concerned about buying property in Blackwall?
Climate risk should be one factor in your decision, alongside price, location, and amenity. An informed buyer understands the specific risks at a property address and factors insurance costs and climate projections into their assessment of long-term value.
What climate projections should I know for Blackwall?
Key projections for New South Wales from CSIRO include increased average temperatures, more frequent hot days, changes in rainfall seasonality, longer fire seasons, and potential increases in extreme rainfall intensity. These trends inform the long-term outlook for Blackwall.
What are the main climate risks in Blackwall?
ClimateNest's suburb model rates Blackwall'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 Blackwall.
