HumeLink is a new 500kV transmission line which will connect Wagga Wagga, Bannaby and Maragle. It is one of the NSW’s largest energy infrastructure projects, with about 365 kilometres of proposed new transmission lines and new or upgraded infrastructure at four locations.

Australia needs to transition to a greater mix of low-emission renewable energy sources, such as wind and solar, to meet our future energy demands. HumeLink will enable a more reliable and more sustainable grid by increasing the amount of renewable energy that can be delivered across the national electricity grid, helping to transition Australia to a low carbon future. 

Critical State Significant Infrastructure (CSSI) projects are deemed to have state significance due to size, economic value or potential impacts.  In 2018, the NSW Minister for Planning and Public Spaces - formerly known as the NSW Minister for Planning - declared Snowy 2.0 and Transmission Project to be a CSSI under the Environmental Planning and Assessment Act 1979 (EP&A Act). Being part of the Transmission Project associated with Snowy 2.0, HumeLink was also declared a Critical State Infrastructure (CSSI) project. 

The project underwent a comprehensive environmental assessment process, including the preparation and public exhibition of an Environmental Impact Statement (EIS), followed by a Submissions Report and an Amendment Report. These assessments considered biodiversity, heritage, social and community impacts.

Planning approval was granted by the NSW Government in November 2024, and Commonwealth environmental approval under the EPBC Act was received in December 2024. The project is subject to conditions set out in both approvals to manage and mitigate environmental impacts.

Transgrid continues to engage proactively with landowners, councils, Indigenous communities and local groups throughout the construction phase.

Engagement activities include:

• Community information sessions and drop-in events
• Participation in local festivals and regional events
• Regular newsletters, project updates and work notifications
• Ongoing consultation through Construction Reference Groups
• A Community Investment and Benefits Program to support local initiatives
• Dedicated Community Engagement Place Managers to support affected landowners across the project footprint.

Main construction works are progressing across both HumeLink East and West. Current activities include tower foundation drilling and concreting, tower erection and assembly, and upgrades or construction at substations including Gugaa, Maragle, Bannaby and Wagga Wagga. Stringing of transmission lines is expected to begin in early 2026.

Laydown areas and access tracks are being progressively established, with several already functional and supporting current works. Worker accommodation facilities at Tarcutta, Yass and Adjungbilly have been completed and are now in use. A worker accommodation facility at Kunama, near Batlow, is expected to start housing workers in November 2026.

Construction will continue to advance through multiple work fronts, with a strong focus on minimising community impacts and maintaining compliance with environmental conditions.
