Senior environmental specialist Simone Marsh, a former Queensland bureaucrat, has blown the whistle on the way major coal seam gas projects were approved in the state in 2010.
Ms Marsh told the ABC's Four Corners program she did not have any of the basic site information, baseline studies and details about infrastructure placement which were necessary to properly assess the environmental impact of the projects.
Ms Marsh told the ABC she repeatedly raised concerns about the lack of information supplied by the energy firms.
The program said 900 pages of documents obtained through a freedom of information request supported Ms Marsh's claims.
"I'm confident, from what I've seen, that the right processes were followed," industry spokesman Rick Wilkinson, the chief operating officer of the Australian Petroleum Production and Exploration Association, told the program.
