Within the past six months, Adani representatives have had forty meetings with the federal government to discuss the Carmichael coal mine project.

Greens Senator Larissa Waters says the number meetings suggest a cosy relationship between the two, further stating the environment department should be a regulator and protector of the planet, rather than facilitating the development of the coal mine.

Late last month the company announced it would self finance its controversial mine, but still requires approval from state and federal governments for several measures.
