Offshore project proposals - public comment

Providing the public with opportunities for participation and consultation is an integral part of environmental impact assessment and assists in ensuring responsible offshore petroleum environmental management.

NOPSEMA publishes offshore project proposals (OPP) that are open for public comment following its determination that the OPP is suitable for publication. The public then have an opportunity to review and provide comment on the OPP.

All public comment submissions, including any objections or claims about the project or an activity in the project, are to be made directly to NOPSEMA. A copy of the comments received will be provided to the proponent for their consideration. The proponent must then submit to NOPSEMA a consultation report that includes a summary of the comments received, an assessment of the merits of each objection or claim about the project or any activity within the project, a statement of their response to each comment, and a description of any changes made to the OPP as a result of an objection or claim.

If the OPP meets the criteria set out in the Environment Regulations and the OPP is accepted, NOPSEMA will publish the final OPP in full on its website.

For more information about OPPs see the Offshore Project Proposals page.
