More than 50 locals attended a council-initiated climate change forum last month at Tidal Waters Resort.

Tasmanian Coastal Adaptation Decision Pathways project manager John Harkin, SGS Economics and Planning general manager Clive Attwater and Pitt and Sherry lead consultant Sven Rand spoke about the challenges facing the region concerning climate change.

Mr Attwater said St Helens was already seeing the effects of climate change and Mr Rand presented his findings from the Break O'Day Coastal Risk Management Plan.

"The rainfall intensity within the municipality is already the highest in the state, with potential increases projected to affect the (region) more than other areas of the state," Mr Rand said.

"This changed rainfall is likely to contribute to greater frequency of flooding events, exacerbating current erosion and inundation.

"When considered in combination with projected changes in sea level as a result of climate change, the potential effects will mean low-lying infrastructure and property will become increasingly vulnerable, prompting likely requirements for adaption in the future."

General manager Des Jennings said public feedback would help the council to provide a local perspective and provide further assistance to workshops in February.

"Adapting to climate change will be a challenge for the council," he said.
