In order to improve the effectiveness of National Offshore Petroleum Safety and Environmental Management Authority (NOPSEMA), with similar benefits for State or Territory regulators, attention should be given to the following actions.
a) Ministers should consider developing an overarching national understanding under which Commonwealth and State or NT regulators are expected to work cooperatively in respect of a large or complex Offshore Petroleum and Greenhouse Gas Storage (OPGGS) project or activity that requires their regulatory attention in their respective jurisdictions.
b) The aim of that cooperation would be to ensure that, as far as possible:
i. information about such projects is shared,
ii. regulatory actions are co-ordinated under a regulatory plan relating to the project or activity;
iii. approvals and other necessary steps in each jurisdiction occur speedily, 
iv. possible regulatory gaps or inconsistencies arising from the crossjurisdictional nature of the project or activity are identified and addressed; and
v. there is continuous improvement in the cooperative regulatory inter-action.
c) The understanding would provide a framework for MOUs or similar arrangements between regulators and provide accountability by requiring annual reporting to Ministers on:
i. the OPGGS projects or activities that had come within the scope and application of the MOUs or similar arrangement;
ii. how well the MOUs or other arrangements were working;
iii. what action had been taken or should be taken to improve regulatory cooperation;
iv. whether any significant regulatory gaps or inconsistencies had been identified.
d) To allow for a smooth transition to the Ministerial understanding and supporting regulatory cooperation, the understanding should be developed for early consideration by Ministers.
