Approved projects and activities

This page contains information about projects and activities that have been approved.

Offshore projects

An offshore project is undertaken to recover oil and/or gas and a number of petroleum activities will be undertaken throughout a projects lifecycle such as development, well construction, facility installation, production operations and decommissioning.

Each project page contains an overview of the project and links to individual activities that are underway for the relevant project. Only development activities that have an ‘in force’ environment plan (EP) are displayed on project pages. Other activities that previously formed part of the project and are no longer underway can be found on the historical activities page.

Offshore projects in Commonwealth waters that were approved prior to NOPSEMA's establishment, and those with an accepted offshore project proposal (OPP) are also displayed on this page. For more information about the OPP assessment process see the OPP page.


Activities listed on this page have an ‘in force’ environment plan accepted by NOPSEMA. Each activity page contains an overview of the activity, an activity location map and titleholder contact details. Related environment plan assessment information can also be accessed for each activity.

Activities have been categorised as exploration (and other related activities) or development, noting only development activities are linked to an offshore project.
