Wangan and Jagalingou man Adrian Burragubba has also denied claims from Adani that he was encouraged to pursue the failed legal action by environmental groups.

Mr Burragubba was formally bankrupted in the Federal Court in Brisbane on Thursday.

His property will be held until $600,000 in legal costs are paid to the miner following unsuccessful legal attempts to stop the Galilee Basin project.

Activists who try to delay projects through legal action need to be held to account - and the funds, if paid, will be donated to charity, Adani said in a statement on Friday.

Adani maintains Mr Burragubba represents a minority of W&J people in opposing the mine, with traditional owners voting 294-to-one in favour of a land use agreement that will extinguish their native title.

"Mr Burragubba refuses to accept the voice of his own people," Adani Australia says.

Mr Burragubba said he would keep speaking out against the mine.

"This bankruptcy means nothing to me," he said in a statement.

"My family were removed from the land by governments and everything that was rightfully ours was taken from us."

Adani said environmental groups appear to have abandoned Mr Burragubba.

But Mr Burragubba says his court actions did not involve environmental groups.

"My opposition to the Adani protect was based entirely upon my culture and traditional law and custom," Mr Burragubba says in an court affidavit sent to AAP.

"I have been a focal point of indigenous opposition to the Adani project; however, I am not the only member of my people to oppose it."

He says he will hold the company to account over the current land use agreement.
