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 Unanderra

Flood

Unanderra faces 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

Unanderra has a moderate bushfire risk due to nearby bushland. Hotter, drier conditions are expected to increase the frequency and intensity of bushfires.

Key drivers:

  • ·Increased temperatures
  • ·Drier conditions

Heat

Unanderra 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

Unanderra faces a moderate risk from coastal hazards due to sea level rise and storm surges. This could lead to erosion and inundation of low-lying areas.

Key drivers:

  • ·Sea level rise
  • ·Increased storm intensity

What This Means for Property Owners

Insurance Outlook

Insurance premiums may increase in the future due to climate risks.

Price Impact

Properties in high-risk areas may experience a decrease in value.

Buyer Checklist

  • 1.Check flood maps and bushfire prone area designations.
  • 2.Assess the property's vulnerability to heatwaves.
  • 3.Consider the potential impact of sea level rise.
  • 4.Obtain a building inspection report.

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 Unanderra's Climate Risk Profile

Unanderra, located in the City of Wollongong, is susceptible to a range of climate-related hazards. Its proximity to waterways and the coast makes it vulnerable to flooding and coastal erosion. The increasing frequency and intensity of heatwaves also pose a significant threat to public health.

The risk of flooding in Unanderra is driven by increased rainfall intensity and sea level rise. Low-lying areas are particularly vulnerable, and infrastructure may be at risk. Bushfire risk is also present due to the presence of nearby bushland, with hotter, drier conditions increasing the likelihood of fires.

Heatwaves are becoming more frequent and intense, posing a risk to vulnerable populations. The urban heat island effect can further exacerbate these conditions. Coastal hazards, such as sea level rise and storm surges, can lead to erosion and inundation of low-lying areas.

Addressing these climate risks requires a combination of mitigation and adaptation measures. Reducing greenhouse gas emissions is essential to slow the pace of climate change. Local adaptation measures, such as improving drainage infrastructure and implementing heatwave early warning systems, can help to reduce the impacts of climate change on the community.

Suburb pages describe the local picture. The address-level assessment, with its data sources and its dollar projections, is in the ClimateNest report.
