RISING sea levels caused by climate change will adversely affect Fraser Island, a conference has heard.
The Sixth Biennial Fraser Island Conference was held this week on the Sunshine Coast to discuss the WorldHeritage-listed site.
Described by organiser John Sinclair of the Fraser Island Defenders Organisation as the most successful conference ever, the event focussed on the future of the island.
Mr Sinclair said the "most outstanding sand feature in the world" was at risk with climate change, because of its easily eroded surface.
"Fraser Island is probably going to be affected on a size basis by climate change more seriously possibly than the Great Barrier Reef, which is a sad thing for a World Heritage site," he said.
"It's the most 'erodible' surface, it's all sand, it's not rock or anything else."
Mr Sinclair said it was now important for the speakers, who included a botanist, ecologist and dingo experts, to share their knowledge.
"If you don't know the problems then you can't manage them," Mr Sinclair said.
