Environmental assessment
Star of the South is being assessed under both Commonwealth and Victorian environment impact assessments processes.
We prepared a draft Commonwealth Environmental Impact Statement (EIS) to seek approval for the entire project under Australia’s national environmental law, and a Victorian Environment Effects Statement (EES) to assess works in Victoria for the project’s underground transmission cables.
Public review and comment of both assessments was invited between 18 May and 29 June 2026.
About the assessments
Our assessments bring together years of scientific research, consultation and specialist technical studies.
The draft EIS provides information about:
- The project and why it’s proposed
- How it will be constructed, operated and decommissioned
- The environmental studies we’ve completed
- Potential impacts and how we propose to address them.
The EES assesses works in Victoria to construct, operate and decommission underground cables.
Their purpose is to help communities and government understand the project in detail before approval decisions are made.
What was assessed?
The draft EIS and EES were informed by 26 technical studies.
These studies involved field work, consultation, and technical analysis. Study methods and findings are documented in technical reports and summarised, where relevant, in the EIS and/or EES.
These studies were undertaken by technical specialists to ensure the EIS and EES address government requirements.
During the 6-week public review period, all EIS and EES documentation was available online and at local venues.
20 members of our engineering, environment, executive and engagement teams enjoyed speaking with locals at:
- 5 community drop-in sessions
- 4 pop-up information stalls
- 2 commercial fishing sessions
- 2 Traditional Owner sessions
- 1 webinar
Thank you to everyone who engaged with us during this time.
