flood Risk
South Perth faces a moderate risk of flooding, primarily from riverine sources and intense rainfall events. The Swan River poses a constant threat, and localized flooding can occur due to inadequate drainage.
Primary Drivers
- ·Increased rainfall intensity
- ·Sea level rise
- ·Urban development reducing permeable surfaces

coastal Risk
South Perth is exposed to coastal risks due to its proximity to the Swan River and the coast. Sea level rise and storm surges can lead to erosion and inundation.
Primary Drivers
- ·Sea level rise
- ·Increased storm surge intensity
- ·Erosion

bushfire Risk
Bushfire risk in South Perth is relatively low due to its urbanized environment and distance from large bushland areas. However, parks and reserves can still pose a localized risk.
Primary Drivers
- ·Proximity to parks and reserves
- ·Dry vegetation in summer

The urban heat island effect contributes to higher temperatures in South Perth compared to surrounding areas. Increased tree canopy cover can help mitigate this effect.
Coastal Evidence
- Distance to Coast
- 2 km
- Sea Level Rise Exposure
- Low-lying areas are vulnerable to sea level rise.
- Erosion Risk
- Some areas along the Swan River are at risk of erosion.

Climate Outlook to 2050
Projections based on CSIRO and BOM climate modelling. Scenario: RCP4.5
| Hazard | Today | 2030 | 2050 |
|---|---|---|---|
| flood | 6.0 | 6.5(+0.5) | 7.0(+1.0) |
| bushfire | 3.0 | 3.1(+0.1) | 3.3(+0.3) |
| heat | 7.0 | 7.4(+0.4) | 8.5(+1.5) |
| coastal | 6.0 | 6.3(+0.3) | 7.2(+1.2) |
Under a moderate emissions scenario, South Perth is projected to experience a slight increase in overall climate risk by 2030. Flooding and heat risks are expected to increase the most.

Learn moreAbout South Perth's Climate Risk Profile
South Perth, located on the Swan River, is vulnerable to a range of climate-related risks. The suburb's low-lying areas are susceptible to flooding from both riverine and rainfall sources. Climate change is projected to increase the intensity and frequency of extreme rainfall events, further elevating the flood risk.
Heatwaves are becoming more common and intense in South Perth, posing a significant threat to public health, especially for vulnerable populations. The urban heat island effect, caused by the concentration of buildings and paved surfaces, exacerbates the heat.
Coastal erosion and inundation are also concerns for South Perth, given its proximity to the Swan River and the coast. Sea level rise is expected to worsen these risks, potentially impacting infrastructure and property values.
While bushfire risk is relatively low compared to other areas in Western Australia, parks and reserves within and around South Perth can still pose a localized threat, particularly during dry summer months. Residents should maintain their properties to reduce fuel loads and be aware of bushfire safety guidelines.
