The announcement came a day after Adani secured the final approval for a permanent rail line for the controversy-hit project despite protests from green groups.
Adani's efforts to build one of the world's largest coal mine project in Australia's Queensland state has been hampered time and again since its launch six years ago.

"There will be early works we plan to start in the quarter of June-July and we would want to start the main works from the last quarter of the year."

Adani group chairman Gautam Adani met Palaszczuk today to discussregional project centres, as well as progress on the mine and associated infrastructure.
Palaszczuk said, "I have got an ironclad guarantee from Mr Adani that there will be no 457 visas as part of the workforce for this major project."
"Adani is committed to remaining engaged in the development of the indigenous and regional communities as demonstrated in today's announcement," Adani said.
"Adani group is committed to nation building projects in the energy and infrastructure space which will create thousands of jobs in regional Queensland and alleviate millions in India of poverty," he added.
Janakaraj said, "This is a significant commitment by Adani
to regional Queensland where the Carmichael mine and associated projects will generate10,000 jobs directly and indirectly, and I ampleased that each of the regional centreswillbenefit from the Carmichael projects."
Meanwhile, anti-mine campaigners continued to protest against Adani's coal and mine project in the state.
The controversial project involves dredging 1.1 million cubic metres of spoil near the Great Barrier Reef Marine Park, which will then be disposed off on land.
A federal court in August last year had revoked the original approval to the project due to environmental concerns. In October last year, the project got a new lease of life after the Australian government gave its re-approval.
In October this year, the Queensland Government announced invoking special powers to help progress the Adani's project by giving it special 'prescribed project status'.
