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 Oyster Bay
Flood
Oyster Bay has 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.
Key drivers:
- ·Increased rainfall intensity
- ·Sea level rise
Bushfire
Oyster Bay faces a moderate bushfire risk due to its proximity to bushland. Hotter, drier conditions are expected to increase the frequency and intensity of bushfires.
Key drivers:
- ·Increased temperatures
- ·Decreased rainfall
Heat
Oyster Bay is likely to experience more frequent and intense heatwaves. This poses a risk to vulnerable populations, such as the elderly and those with chronic health conditions.
Key drivers:
- ·Increased greenhouse gas emissions
- ·Urban heat island effect
Coastal
Oyster Bay is exposed to coastal risks such as sea level rise and erosion. These risks are expected to worsen with climate change, potentially impacting coastal infrastructure and properties.
Key drivers:
- ·Sea level rise
- ·Increased storm surge

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 Oyster Bay's Climate Risk Profile
Oyster Bay, located in southern Sydney, is vulnerable to a range of climate-related hazards. Its proximity to waterways increases the risk of flooding, while nearby bushland poses a bushfire threat. The suburb is also susceptible to heatwaves and coastal hazards such as sea level rise and erosion.
Climate change is projected to worsen these risks. Increased rainfall intensity is expected to lead to more frequent and severe flooding events. Hotter, drier conditions will increase the likelihood of bushfires. Rising temperatures will result in more frequent and intense heatwaves. Sea level rise will exacerbate coastal erosion and inundation.
These changes could have significant impacts on Oyster Bay. Property values may be affected, and infrastructure could be damaged. The health and well-being of residents, particularly vulnerable populations, could be at risk. It is important for residents and local authorities to take steps to adapt to these challenges.
Adaptation measures could include improving drainage infrastructure to reduce flood risk, implementing bushfire management strategies, and developing heatwave response plans. Protecting and restoring coastal ecosystems can also help to mitigate the impacts of sea level rise. By taking proactive steps, Oyster Bay can build resilience to climate change and protect its community and environment.
