Yet another company has announced plans to end ties to Adani's controversial Carmichael coal mine in central Queensland.

Cardno chairman Michael Alscher said the infrastructure firm would be ending work for a subcontractor to Adani in coming weeks and would not seek any future tenders with the Indian mining company.

"Given the project and the controversy around that, it is best if we not participate in the project at all," Cardno's chairman says of the Carmichael mine. Credit:Peter Braig

He said the mine had been a contentious issue with staff and customers.

"As a company, we have decided that we will no longer do any further work with the company," Mr Alscher told the Cardno annual general meeting in Sydney on Thursday.
