In November 2015, ACF filed a case to challenge the federal government's approval of Adani Mining's Carmichael coal mine ('Carmichael case') under the Environment Protection and Biodiversity Conservation Act ('EPBC Act). The purpose of the case was to highlight Australia's failed environmental laws, Australia's failure to act on climate change and to stop the Carmichael coal mine – a mine that would be the largest in the Southern Hemisphere. ACF argued that in making his decision, the Environment Minister did not correctly or fully consider the impact or likely impact of pollution on the Great Barrier Reef from the coal burnt in India.
