NOPSEMA is Australia’s independent regulator for health and safety, well integrity and environmental management for offshore petroleum and greenhouse gas storage activities in Commonwealth waters (comprising the first three nautical miles of the territorial sea) and coastal waters where regulatory powers and functions have been conferred.

NOPSEMA assesses key permissioning documents, such as an environment plan, against strict criteria as set out in the Act and its regulations; inspects an oil and gas company's compliance with the Act, its regulations and accepted permissioning documents; investigates all reports of non-compliance; takes enforcement action to rectify non-compliance and hold parties to account and; provides advice on safety, well integrity and environmental management matters to improve understanding, promote compliance, and encourage continuous improvement.

NOPSEMA does not administer offshore petroleum titles or provide petroleum exploration acreage release. 

The petroleum exploration acreage release is the responsibility of the Department of Industry, Science and Resources. 

The administration of offshore petroleum titles is the responsibility of the National Offshore Petroleum Titles Administrator (NOPTA).
