Australian High Commissioner to India Harinder Sidhu said that all its environmental approvals have been granted to the company a couple of months ago.
"...And so effectively, it has everything it needs now to start its work. As far as I know, the way is clear for Adani at the moment," she said here at a function.
Adani has proposed to build one of the world's largest coal mines in Australia with a proposed investment of about USD 16.5 billion.
The project is located near the fragile Great Barrier Reef.
Environmental groups had contended that the mine would affect groundwater, climate change and biodiversity, including black-throated finches.
