What This Means for Property Owners
Insurance Outlook
Insurance premiums are likely to increase due to rising climate risks, particularly for properties in flood-prone or coastal areas.
Price Impact
Properties in high-risk areas may experience a decrease in value or slower price growth compared to less vulnerable locations.
Buyer Checklist
- 1.Check flood maps and coastal inundation zones.
- 2.Assess the property's vulnerability to heatwaves.
- 3.Inquire about council plans for climate adaptation.
- 4.Review insurance coverage for climate-related risks.
- 5.Consider the long-term impact of climate change on property value.

Learn moreAbout St Kilda's Climate Risk Profile
St Kilda, a vibrant suburb of Melbourne, is increasingly vulnerable to the impacts of climate change. Rising sea levels pose a significant threat to its coastline, potentially leading to erosion and inundation of low-lying areas. The frequency and intensity of heatwaves are also increasing, exacerbating the urban heat island effect and placing vulnerable populations at risk.
Flooding from heavy rainfall and stormwater runoff is another concern, particularly in areas with poor drainage. While the risk of bushfires is relatively low due to the suburb's urban environment, parks and reserves can still pose a localized threat. It is crucial for residents and businesses to take proactive measures to adapt to these changing conditions.
The City of Port Phillip is actively working to address climate change through various initiatives, including improving drainage infrastructure, promoting green spaces, and implementing coastal protection measures. However, individual actions are also essential to mitigate the risks and build resilience.
Preparing for extreme weather events, such as heatwaves and floods, is crucial. This includes having emergency plans in place, ensuring adequate insurance coverage, and taking steps to reduce energy consumption and water usage. By working together, the community can protect St Kilda's unique character and ensure its long-term sustainability.
Longer term projections indicate that St Kilda will experience more frequent and intense heatwaves, increased coastal inundation, and more intense rainfall events. These changes will require significant investment in infrastructure and adaptation measures to protect the community and its assets.
It is important to stay informed about the latest climate projections and adaptation strategies. By understanding the risks and taking proactive measures, residents and businesses can help to build a more resilient and sustainable future for St Kilda.
