THE Gold Coast would lose its beaches. Sydneys Opera House would flood every day instead of every 100 years. And 48,000 Victorian homes would be swallowed. All by the end of the century.

Theyre the predictions in the latest report by the Climate Council, which assesses the nations vulnerability to rising sea levels by 2100.

The report Counting the Costs: Climate Change and Coastal Flooding, warns that more than half the Australian coastline is vulnerable to recession from the rising ocean, with 80 per cent of the Victorian coast and 62 per cent of the Queensland coast at risk.

Authors of the report suggest the Gold Coast, which hosts over 11 million visitors a year could be the hardest hit.

The beach is one of the main drawcards for visitors and as sea levels rise, there is no opportunity for the beach to move landward because of the adjacent high-rise developments.

Rising sea levels would also cause headaches for Sydney, with todays one-in-100-year flood to occur every day or so by 2100.
