Queensland Premier Annastacia Palaszczuk has been confronted in India by Australians opposed to Adani's planned central Queensland coal mine.

Ms Palaszczuk arrived to inspect Adani's home port when she was met by businessman and environmentalist Geoffrey Cousins and Whitsundays tourism operator Lindsay Simpson.

Mr Cousins had sent a letter — signed by 90 prominent Australians — to Adani chairman Gautam Adani, urging him to abandon the Carmichael coal project and invest instead in renewables.

"I hope you saw the letter," Mr Cousins said to Ms Palaszczuk.

"Yes we did," the Premier replied, before Ms Simpson accused Ms Palaszczuk of risking tourism jobs and putting the reef at risk by supporting the Adani project.

"Sixty nine thousand jobs in tourism and you are single-handedly, along with the other government, wrecking the reef," Ms Simpson said.

"There is no greater supporter of the Great Barrier Reef than me and my government," the Premier replied.

"All of you have jobs, and there are regional Queenslanders that are fighting for jobs (from coal mining). Ten thousand regional jobs."

"Rubbish, absolute rubbish," Ms Simpson responded, as Ms Palaszczuk got into her car to continue her visit.

The Premier is travelling with regional mayors and will also talk to Mr Adani about a solar farm at Moranbah and Queensland agricultural exports.
