Queensland's top tourist destinations are under threat from climate change, according to the latest report from the Climate Council.

The "Icons at Risk: Climate Change Threatening Australian Tourism" report released on Thursday claims the state's iconic beaches, wilderness areas and in particular the Great Barrier Reef are under imminent threat due to changes in the Earth's climate.

Ecologist Professor Lesley Hughes said in addition to the environmental concerns surrounding climate change, it was also threatening the state's billion-dollar industry.

"In 2016 alone, more than 2.5 million international visitors arrived in the state, bringing in more than $5.2 billion dollars," Professor Hughes said.
