Overall Risk Score
Hazard Breakdown
Flood, bushfire, heat, coastal and storm exposure are all assessed in this area. The score that matters is the property's own: a ClimateNest report scores the address across eight hazards, with insurance and value projections to 2050.
Climate Hazard Breakdown for Port Hacking
Flood
Port Hacking faces a moderate risk of flooding due to its proximity to the Port Hacking waterway and low-lying areas. Intense rainfall events can lead to stormwater runoff and riverine flooding.
Key drivers:
- ·Increased rainfall intensity
- ·Sea level rise
Bushfire
The suburb has a moderate bushfire risk due to the presence of surrounding bushland. Hot, dry conditions and strong winds can increase the likelihood of bushfires.
Key drivers:
- ·Dry vegetation
- ·High temperatures
Heat
Port Hacking is susceptible to heatwaves, particularly during the summer months. Rising temperatures can pose health risks to vulnerable populations.
Key drivers:
- ·Rising global temperatures
- ·Urban heat island effect
Coastal
Located near the coast, Port Hacking is exposed to coastal erosion and sea level rise. These factors can impact infrastructure and property values.
Key drivers:
- ·Sea level rise
- ·Storm surges

How the region's climate is projected to change
Regional projections, not a forecast for this street. Figures are from the WA Department of Water and Environmental Regulation's climate projections for the South Western Flatlands region, which draws on CSIRO and Bureau of Meteorology modelling.
Temperature
+0.5 to 1.1°C by 2030
Above the 1986–2005 climate, on all emissions scenarios. By 2090, 1.2 to 2.0°C under intermediate emissions or 2.6 to 4.0°C under high emissions.
Rainfall
Winter rain down up to 15% by 2030
The South West has been drying since 1970, and the decline has been larger than anywhere else in Australia. Heavy rainfall events are projected to become more intense even as totals fall.
Fire weather
Harsher, magnitude uncertain
High confidence that fire weather becomes harsher, low confidence in the size of the change, because it depends heavily on summer rainfall.
Sea level
+0.12 m by 2030
At the Fremantle gauge, range 0.07 to 0.16 m. Very high confidence that sea levels continue to rise through the century.

Learn moreAbout Port Hacking's Climate Risk Profile
Port Hacking, a suburb in southern Sydney, is characterized by its proximity to the Port Hacking waterway and surrounding bushland. This unique geography contributes to the suburb's vulnerability to a range of climate-related hazards.
Flooding is a significant concern, with low-lying areas susceptible to inundation during heavy rainfall events. The increasing intensity of rainfall due to climate change is expected to worsen this risk, potentially impacting homes and infrastructure.
Bushfires also pose a threat, particularly during the dry summer months. The presence of nearby bushland increases the risk of fire spreading to residential areas. Residents need to be vigilant and prepared for bushfire emergencies.
Heatwaves are becoming more frequent and intense, posing health risks to vulnerable populations, especially the elderly and those with pre-existing health conditions. Rising temperatures can also strain energy infrastructure and increase the risk of blackouts.
Finally, coastal erosion and sea level rise threaten properties located near the Port Hacking waterway. These factors can lead to property damage, loss of amenity, and decreased property values.
