Narrabri Lateral Pipeline

Narrabri Lateral Pipeline

To connect the Narrabri Gas Project (NGP) to the HGP, Santos is finalising plans for the Narrabri Lateral Pipeline.

The proposed pipeline will provide the ‘missing link’ to allow for the transmission of natural gas to the existing NSW natural gas transmission network near Newcastle.

The project will extend for about 50-60 kilometres from the approved NGP gas processing facility at Leewood to the HGP east of Baan Baa. The final length of the pipeline will be dependent on the selection of the alignment. The pipeline will be primarily located underground, with associated aboveground infrastructure including isolation valves, meters, and regulators.

Santos is committed to minimising the impact on communities, landowners, and the environment. Santos has commenced consultation with directly affected landholders and councils representing the broader communities and encourages landholders to engage with us so that we can understand their feedback and insights about the project.

The project will require approval by the NSW Government.

Environment Protection and Biodiversity Conservation Act 1999 (EPBC Act) assessment

In November 2024, Hunter Gas Pipeline Pty Ltd referred the Narrabri Lateral Pipeline Project to the Australian Government, Department of Climate Change, Energy, the Environment and Water (DCCEEW) in accordance with the Environment Protection and Biodiversity Conservation Act 1999 (EPBC Act). In February 2025, the Australian Government determined the Narrabri Lateral Pipeline to be a ‘controlled action’ requiring assessment and approval under the EPBC Act due to potential impacts on listed threatened species and communities (sections 18 and 18A of the EPBC Act). The Narrabri Lateral Pipeline project will be assessed under the bilateral agreement with the NSW Government, with a single Environmental Impact Statement prepared for public comment addressing both Commonwealth and State matters. The Narrabri Lateral Pipeline EPBC Referral (2024/10050) decision is available on the Commonwealth EPBC Public Portal.
