Making a submission to NOPSEMA

For regulatory submissions, NOPSEMA only accepts electronic documents. This reduces the need for printing and managing hard copies and is compatible with NOPSEMA’s electronic document and records management system. If hard copies are received, these will be returned to the sender (particularly for large submissions). 

NOPSEMA requests one electronic consolidated text searchable PDF copy of each submission to be provided. The submission, including any attachments, should be clearly labelled so that the nature of the submission can be easily identified. For public submissions on Offshore Project Proposals please refer to the OPP open for public comments page.   

NOPSEMA will provide submission outcomes via electronic means, where consent been received. See the consent to electronic communications page for more information.

Secure file transfer for all other regulatory submissions

  • provides for an attachment size of at least 250Mb, while email only provides for 10Mb per message.

There are no set limits on the number of documents that may be attached to each message. It is often more convenient to combine a large number of documents into a ZIP archive to be attached to a message, as this reduces the number of steps in preparing a submission. The current size limit for single documents is displayed at the bottom of the submission form. This is set to 250 megabytes.

Submitted documents are limited to a list of accepted file types, which are listed near the bottom of the form. Click on "Accepted File Types" to see the full list.

Acknowledgement of your submission

On sending your submission you should see an immediate response at the top of the submission page indicating 'Files sent successfully'. An email message will later be sent to you once your message and documents have been received. Please note that this acknowledgement of receipt does not signify the adequacy of the submission for any regulatory purpose, only that it has been received. Where the law requires submissions to satisfy specific validity criteria, a separate notice will be given after appropriate checks are completed.

Security and confidentiality of your submission

Secure File Transfer is designed to ensure the confidentiality and reliable delivery of your submission. Care has been taken in the selection and construction of the system to apply good IT security practice and establish appropriate technical and personnel controls. All traffic to the system is encrypted and protected by multiple access control layers. The system is not operating on public cloud infrastructure but on servers operated by NOPSEMA within Australia.
