Protesters will rally on William Street at 10am this morning outside the Queensland Cabinet meeting.

Members of the Stop Adani movement will gather to demand that Labor keep their election promise to veto a government loan to Aurizon, one of Australia's largest freight operators.

The proposed loan to Aurizon is speculated to be in aid of building a railway line from a port city to the Adani mine, making it easier and cheaper for the project to go ahead.
