The investigation found the two departments in charge of regulating the industry were not sharing data, making it difficult to pinpoint how many coal seam gas activity leases had been handed out.

"Neither we nor the regulators could be sure of identifying all authorities to prospect, petroleum leases, and environmental authorities for coal seam gas activities," the report states.

"Consequently, we and the regulators were unable to verify the complete authorities and leases for coal seam gas activities with any degree of confidence."

Lock the Gate national coordinator Namoi Hogan said the report showed the industry had been allowed to run rampant across the state without adequate regulation.

"In their mad rush to exploit the state's gas resources, successive Queensland governments permitted the proliferation of the risky CSG industry without a safe, reliable regulatory framework in place," Ms Hogan said.

"The lack of consistent regulation is particularly worrying given governments have allowed polluting gasfields to pockmark some of the state's most valuable agricultural land.

"The report reveals a litany of serious ongoing concerns from landholders about consultation failure, failure to compensate for negative impacts, and failure to protect agricultural interests."

The two regulating departments, the Department of Natural Resources, Mines and Energy (DNRME) and the Department of Environment and Science (DES), have accepted the report's recommendation to improve their data sharing.

The report also found coal seam gas activities were not identified separately from the departments' other regulatory activities, nor did they coordinate their planning activities.

"These limitations make it difficult to assess the overall effectiveness of the regulatory framework specific to coal seam gas activities," the report stated.

"Concerns from landholders and other stakeholders persist regarding the effectiveness of the framework in managing issues such as priority agricultural areas, offsite impacts, and the long-term environmental effects of coal seam gas activities."

DNRME will transition to a new online application system within the next two years, which will allow them to specifically identify coal seam gas exploration and production application.
