Workers for Adani's mega coal mine will be sourced from regional Queensland, with the Indian giant's chairman agreeing not to use foreign workers on 457 visas.

Gautam Adani met Premier Annastacia Palaszczuk at the Port of Townsville boardroom this morning, with the northern city named yesterday as the regional headquarters for the $22 billion Carmichael mine.

Ms Palaszczuk said she had an "ironclad" guarantee there would be no 457 visas, however there is no written agreement at this stage.

"I secondly have a guarantee of a Queensland-first policy for jobs, and especially for regional Queensland," Ms Palaszczuk said.

"The coal will be mined in regional Queensland by regional Queenslanders.

"Jobs will return to these small regional mining communities."

But Opposition Leader Tim Nicholls said written assurances would be preferable.

"The Premier has said she takes Mr Adani at this word and that's fine, but I would have thought it would have been better to assure Queenslanders that we had some written commitments that jobs from this project will go to Queenslanders," he said.

The project involves construction of a near-400km rail line from the Carmichael mine site to the Adani-owned and operated bulk coal-loading facility at Abbott Point near Bowen.

Adani had originally proposed to base all of its project offices in Brisbane, however it will now spread its workforce throughout the state.

Bowen and Mackay region will be the regional headquarters for Adani's rail and port operations and maintenance.

Furthermore, Townsville and Rockhampton have been shortlisted to by the fly-in, fly-out hub for the operation.

Alongside those commitments, Adani has also proposed to establish a $200 million large-scale solar project near Moranbah.

Adani Australia chief executive Jeyakumar Janakaraj said the project was "back on track" after series of court challenges, some of which are still pending.

The company estimates 10,000 direct and indirect jobs will be created through the mine, which is estimated to be operational for up to 60 years.

"Today marks the start of regaining momentum," Mr Janakaraj said of the project, which was first slated six years ago.

"The time has been quite lengthy, we have gone through a difficult situation, but this has been resolved with unwavered resolve in terms of the Government and the stakeholders involved."

"The Carmichael mine is primarily aimed at bringing electricity to 100 million people in India, to improve their quality of life and indeed provide them with better health, education and employment opportunities."

But Mr Janakaraj dismissed the protesters' concerns.

"This is where people have to clearly understand this project is a net positive impact on climate change in the world," he said.

"India is a large consumer of coal either way.

"If Australia doesn't produce and give India high quality and highly sustainable mining, it is going to rely on coal that comes from less reliable geographies."

While the mine has federal and state environmental approval, it is still awaiting a water licence and has also applied for a loan from the Federal Government for its rail line.

Ms Palaszczuk said the project has gone through 39 assessments and again promising the Great Barrier Reef and the Caley Valley Wetlands will be protected from the disposal of dredge spoil from the Abbot Point expansion.

Construction on the project is due to begin by June next year.
