About the EIS/EES

Marinus Link has prepared a draft Commonwealth Environmental Impact Assessment (EIS) and a Victorian Environment Effects Statement (EES) through a coordinated process, resulting in a combined EIS/EES addressing the requirements of Commonwealth and Victorian legislation.

More information regarding the environmental assessment of the project is provided at the Environmental Assessment page. Information regarding requirements under Tasmanian legislation in respect of the Heybridge Converter Station and Heybridge Shore Crossing will be available at the Tasmania Environmental Assessments page.

The figure below outlines the primary legislation and the relevant jurisdictions that are applicable to this EIS/EES.

Assessment process

EIS/EES public exhibition

From 31 May – 12 July 2024, Marinus Link’s EIS/EES and draft PSA were on public exhibition. During this time, members of the public were invited to read and make submissions on the documents.

Victorian Inquiry and Advisory Committee

The Victorian Minister for Planning will appoint an independent Inquiry and Advisory Committee (IAC) to consider the EIS/EES, public submissions and to conduct a public hearing regarding the EES and draft PSA commencing in the week beginning Monday 16 September 2024. The Hearing is expected to run for up to nine weeks.

The IAC will hold a Directions Hearing on Tuesday 6 August 2024 to consider the arrangements and timetable for the public hearing.

If you want to present to the IAC regarding Victorian matters you will need to make a written submission, and mark on the online submission form that you would like to be heard.

The IAC will review all submissions made on the exhibited EES and draft PSA documentation. It will provide a report at the conclusion of its hearing to the Minister for Planning on the effects of the project on the Victorian environment.

The IAC will be guided by Terms of Reference issued by the Minister for Planning.

The IAC will not be examining impacts to the Tasmanian environment, Commonwealth marine areas, or Matters of National Environmental Significance (whether located in Victoria or elsewhere). That said, there are likely to be interactions, overlaps or combined effects of works in Victoria and works outside of Victoria on the Victorian environment.

Information on the hearing process and timetable will be published as it becomes available at Victorian Government’s Engage Victoria website.

Following public exhibition of the EIS/EES and a subsequent inquiry, the Victorian Minister for Planning will provide an assessment of the environmental effects of the project in Victoria. The Victorian Minister’s assessment will then inform Victorian statutory decision-makers for the project approvals required under Victorian legislation. For more information on the Victorian approvals process visit the environmental assessment page.


Following receipt of public submissions Marinus Link will finalise the EIS and provide the Commonwealth Minister for the Environment and Water with the EIS, submissions received on the draft EIS, and Marinus Link’s response to those comments. The Commonwealth Minister for the Environment and Water will decide whether the project is approved, approved with conditions, or refused under the EPBC Act.

For more information on the Commonwealth approvals process visit the environmental assessment page.
