Protesters in opposition to Adani say Brisbane peak hour march was only a minor inconvenience compared to if the mine goes ahead.
Rally organiser Catherine Robertson says the protest was angry, loud and occupied major intersections for quite some time with some activists wearing hazmat suits to display the "crime scene" which would unfold in the Galilee Basin and Great Barrier Reef if the mine was not stopped.
The protest was organised by the same groups behind a similar protest on June 21 which occupied the Victoria Bridge.
