The report Climate Change Risks to Australia's Coast predicts a sea level rise of 1.1 metres this century and identifies Break O'Day, Central Coast, Waratah-Wynyard and Clarence as the most at risk municipalities.

Minister Assisting the Premier on Climate Change Lisa Singh yesterday said it highlighted the importance of working to combat climate change.

"This does require leadership because we do know there are still some people not taking this seriously enough," she said.

"This is not just government's problem; it's everybody's problem."

Ms Singh said the State Government would be addressing the details of the report and that it may inform the final draft of the state's long awaited coastal policy.

"Tasmania has a strong renewable energy base but that does not make us immune from the effects of climate change, it doesn't make us immune to the effects of sea level rise; they are real and we need to take heed of that," she said.

According to the report, between 87,000 and 11,600 residential buildings in Tasmania may be at risk of inundation from a sea level rise of 1.1 metres and a storm tide associated with a one-in-100 year storm event. The value of the residential buildings at risk is between $2.4 billion and $3.3 billion.

The report also identifies coastal erosion as a key risk associated with climate change and rising sea levels.

It estimates there are about 6100 residential buildings along Tasmania's coastline located within 110 metres of soft, erodible shorelines, of which 1800 are located within 55 metres of soft coast.

Of the coastal local government areas, Clarence, West Tamar and Kingborough have the highest number of such residential buildings, which, according to the report, could be at risk in the absence of coastal protection measures or other adaptation responses.

Ms Singh said she was fully supportive of the Federal Government's response to climate change but she acknowledged there was always more that could be done.

She also urged the Federal Opposition to throw its support behind Prime Minister Kevin Rudd's climate change strategies.
