Rising Sea Levels Threaten More than 267,000 Properties

The report says 250,000 homes worth $274 billion could be lost, and many damages may be excluded from insurance.

  • On Thursday, the Climate Council released the 'Rising Seas, Rising Bills' report, warning that sea level rise could cost Australia at least $855 billion by 2100 across property and land-use losses based on conservative emissions projections.
  • Researchers from the University of Melbourne, the Australian National University, and Global Environmental and Economic Modelling conducted the first nationwide assessment, projecting total damage costs exceeding $850 billion—$274 billion in property losses and $580 billion in land-use damage.
  • Western Australia faces the highest economic impact at about $230 billion by 2100, while Queensland expects $214 billion in damage affecting 93,000 properties; Victoria stands to lose 17,364 homes across prestigious Melbourne suburbs including Brighton and Elwood.
  • Many coastal losses fall under 'actions of the sea,' excluding them from insurance coverage. The Insurance Council of Australia reported that storm surges from Ex-Tropical Cyclone Alfred generated more than 125,000 claims totalling $1.36 billion last year.
  • The Climate Council recommends designating 'no build' zones to preserve shorelines, though Watkins noted adaptation is becoming 'prohibitively expensive' for some councils, requiring collaborative planning across local, state, and federal levels.
