Overall Risk Score

Address-level

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 Outtrim

Flood

Outtrim has a moderate flood risk, primarily due to its proximity to minor waterways and low-lying areas. While major flood events are infrequent, localized inundation can occur during intense rainfall.

Key drivers:

  • ·Intense rainfall events
  • ·Minor waterway overflow

Bushfire

Outtrim is situated in a region with a significant bushfire risk, with surrounding areas of dry sclerophyll forest and grasslands. The risk is elevated during hot, dry, and windy conditions.

Key drivers:

  • ·Proximity to bushland
  • ·Dry vegetation

Heat

The region experiences a moderate risk of heatwaves, with average summer temperatures rising. Increased frequency and intensity of heatwaves pose a risk to vulnerable populations and infrastructure.

Key drivers:

  • ·Rising average temperatures
  • ·Increased frequency of heatwave events

Coastal

Outtrim is located inland and is not directly exposed to coastal erosion or sea-level rise risks.

What This Means for Property Owners

Insurance Outlook

Increasing premiums and potential for higher excess due to bushfire and flood risks.

Price Impact

Potential for negative impact on resale value in higher-risk zones, especially for properties with inadequate mitigation measures.

Buyer Checklist

  • 1.Review current and future flood maps.
  • 2.Assess bushfire attack level (BAL) rating.
  • 3.Check proximity to vegetation and potential fire paths.
  • 4.Investigate local emergency service response times.
  • 5.Understand local council's climate adaptation plans.
  • 6.Inquire about historical weather-related damage.
  • 7.Verify insurance policy coverage and costs.

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.

About Outtrim's Climate Risk Profile

Outtrim, a small rural locality in Victoria, Australia, is subject to a range of climate-related risks that are projected to evolve in the coming decades. The most prominent concern for the area is the risk of bushfires, driven by its location adjacent to significant areas of dry sclerophyll forest and grasslands. These natural landscapes, particularly during prolonged dry spells and hot weather, create conditions conducive to rapid fire spread. The increasing frequency and intensity of extreme weather events, including heatwaves and intense rainfall, further exacerbate these risks.

While Outtrim is not directly on the coast, it is susceptible to localized flooding. This risk is primarily associated with its low-lying topography and the potential for minor waterways to overflow during periods of heavy rainfall. Although major flood events are not a common occurrence, flash flooding can still pose a threat to properties and infrastructure, particularly in low-lying pockets of the suburb.

The region is also experiencing a warming trend, leading to an increased risk of heatwaves. These events, characterized by prolonged periods of extreme heat, can have significant impacts on human health, agriculture, and infrastructure. The projected increase in the intensity and frequency of these heatwaves necessitates careful planning and adaptation measures to protect residents and the local environment.

In terms of property and investment, the increasing awareness of climate risks is likely to influence the property market. Buyers are becoming more conscious of the long-term viability and potential costs associated with properties in climate-vulnerable areas. This can translate into impacts on resale liquidity and potentially affect property values, especially in areas with higher perceived risks.

Adaptation and mitigation strategies are crucial for enhancing the resilience of Outtrim. This includes community-level preparedness for bushfires, improved stormwater management for flood mitigation, and measures to reduce the urban heat island effect where applicable. Individual property owners can also take steps to protect their homes and assets, contributing to the overall resilience of the community.

Frequently Asked Questions

What is the primary bushfire risk for Outtrim residents?

The primary bushfire risk stems from the surrounding dry sclerophyll forests and grasslands, especially during hot, dry, and windy conditions. Residents should have a well-defined Bushfire Survival Plan.

How susceptible is Outtrim to flooding?

Outtrim has a moderate susceptibility to localized flooding due to its low-lying areas and proximity to minor creeks. Intense rainfall events can cause inundation, particularly in lower-lying parts of the suburb.

Are there specific bushfire overlays affecting property development in Outtrim?

Yes, Outtrim is designated as a Bushfire Prone Area. This means that property development is subject to specific building regulations and planning requirements aimed at mitigating bushfire risk, often requiring a Bushfire Attack Level (BAL) assessment.

What are the projected changes in heatwave frequency for Outtrim?

Climate projections indicate an increase in the frequency, intensity, and duration of heatwaves for the Outtrim region. This means more days above 35°C and potentially longer periods of extreme heat.

Does Outtrim face any sea-level rise or coastal erosion risks?

No, Outtrim is located sufficiently inland and does not face direct risks from sea-level rise or coastal erosion. Its climate risks are primarily related to bushfire, flood, and heat.

Where can I find the official flood maps for the South Gippsland Shire?

Official flood information and maps for the South Gippsland Shire can typically be found on the South Gippsland Shire Council's website under their planning and emergency management sections, or via the Victorian State Emergency Service (SES).
