The Australian Conservation Foundation (ACF) has lost its latest appeal against the Carmichael coal mine.

The ACF was arguing that the Federal Environment Minister failed in his duty to consider the $16 billion mine's impact on the Great Barrier Reef.

“Today's decision is just another step in the most significant environmental campaign of our generation,” ACF spokesperson Paul Sinclar told reporters after the decision as handed down.

“[It] shows that our national environmental laws are broken and are not protecting the places we love, like the Great Barrier Reef.

“We depend on the passion, commitment and determination of the Australian people to stop the Adani mine.”

Federal Environment Minister Josh Frydenberg welcomed the decision.

“[The decision] is consistent with the Commonwealth's interpretation and application of relevant parts of federal environmental law,” he said.

Adani Australia CEO Jeyakumar Janakaraj welcomed the court's ruling too.

“This is the third time this week that these parties have failed in their appeals against earlier court dismissals,” he said.

“Each of these appeals simply tried to delay a project that will create 10,000 direct and indirect jobs.

“The project will also inject $22 billion in royalties and charges into the state coffers to be reinvested back into the broader community.”
