Environmental lawyers have asked Australia's consumer watchdog to investigate Adani's claims that its controversial Queensland coal mine will create a jobs bonanza.

Environmental Justice Australia this week wrote to the Australian Competition and Consumer Commission asking it to investigate what it says is "misleading or deceptive conduct" by the company relating to the Carmichael mine in the Galilee Basin.

"Plenty of evidence suggests Adani's representations about 10,000 direct and indirect jobs are seriously flawed, yet the company continues to mislead people looking for work," said EJA lawyer David Barnden, who said the Queensland Land Court had already ruled the mine would create just 1464 jobs.

The future of the mine has suffered a number of setbacks this week with project funding from China looking increasingly unlikely.
