In December 2016 GPAP published the report 'Off Track: Why NAIF (Northern Australia Infrastructure Facility) can't approve the Carmichael Rail Project' which expressed concerns over NAIF independence and ability to approve a rail line loan while complying with organisational loan eligibility criteria. In late 2017, the Queensland government announced that it would veto any federal NAIF funding for a Galilee Basin rail line, effectively ending the prospect of NAIF subsidising Adani's rail proposal. In February 2018 rail company Aurizon withdrew its NAIF loan application. In July 2019, over 500 protestors gathered at the Brisbane Square with the aim to 'stop the city' demanding the state government to revoke the approval of the mine. The environmental approval for the mine came in June 2019.
