Protesters outside Brisbane magistrates court on Thursday. The Adani mining company received a criminal conviction after it pleaded guilty to giving the Queensland government false or misleading information about land clearing at the Carmichael mine site in 2018.

Mining company pleads guilty to offence at Carmichael mine site.

Prosecutors have called for Adani to be fined $25,000 for giving the Queensland government false or misleading information about land clearing.

The Indian mining company pleaded guilty to the offence in Brisbane magistrates court on Thursday, after the state environment department charged it last year with clearing part of its controversial Carmichael mine site in 2018.

The case relates to information in Adani’s 2017-18 annual return for the central Queensland mine, with the department accusing the miner of failing to report a disturbance area of more than 130 hectares.

It is the first criminal conviction against Adani in Australia. The company has blamed an administrative error.

“Importantly, there was no environmental harm, all relevant works were legal, and fully complied with our project conditions,” Adani said in a statement.

The charge carries a maximum penalty of $3m, but prosecutors are seeking a fine of about $25,000.

The offence has prompted calls from the Greens for the federal government to revoke the coalmine’s approval.

“A criminal conviction is a legal trigger for the federal government to review and revoke Adani’s approval,” Greens senator Larissa Waters said. “If the government keeps ignoring Adani’s breaches, it’s just one rule for coal donors and another for ordinary Australians.”

In 2017, Adani’s Abbot Point coal facility was fined more than $12,000 for releasing water during Cyclone Debbie that contained eight times more sediment than allowed.

The mining giant was granted a temporary emissions licence during the cyclone to allow stormwater to be released due to high rainfall. The company self-reported it had breached the strict conditions of the licence.
