What we heard from our targeted community consultation

We thank you for your time and input

Our latest round of consultation has come to a close and we want to say a huge thank you to everyone who’s taken the time to be part of the conversation.

Air Quality and Greenhouse Gas Assessments

Independent studies are helping ensure the project meets high environmental standards. Explore how air quality, noise, and emissions are being modelled, monitored, and minimised.

Construction Methodology

From underground tunnels to careful site planning, see how international best practice is guiding construction to minimise disruption, protect the landscape, and respect the community.

Traffic and Roads

Safe, well-planned roads are essential during construction and beyond. Find out how the project is working with councils and transport agencies to manage traffic and leave lasting local benefits.

Continuing to enjoy the recreational use of Lake Lyell is important to the community. Constructed in 1982 to provide cooling water for nearby power stations, Lake Lyell has since become a much-loved spot for boating, fishing, and camping.
