Narrabri Lateral Pipeline
The proposed Narrabri Lateral Pipeline (NLP) will connect the Narrabri Gas Project (NGP) to the Hunter Gas Pipeline (HGP), transporting 100 per cent of Narrabri gas to the existing NSW gas transmission network. The NLP project is located in the Narrabri Shire local government area in north-west NSW within the traditional Country of the Kamilaroi (Gomeroi) People. The underground pipeline will span approximately 55 kilometres, starting at the Leewood gas processing facility (about 20 kilometres south-west of Narrabri), running south-east via the Bibblewindi facility, and tying into the approved HGP (approximately 5.5 kilometres south-east of Baan Baa). The NLP will bring economic benefits to Narrabri and surrounding regions, supporting up to 200 jobs during the peak of construction. The NLP will be buried underground with limited aboveground infrastructure.
Santos is committed to minimising the impact on communities, landowners, and the environment. Santos continues to consult with directly affected landholders, councils and the broader communities. We encourage people to engage with us so that we can understand their feedback and insights about the project. The project will require approval by the NSW and Australian Governments.
Santos recently submitted the NLP Environmental Impact Statement (EIS) to the Department of Planning, Housing and Infrastructure (DPHI). DPHI has placed the EIS on public exhibition from 20 November to 18 December 2025, inviting the community to review the document and provide feedback.

Environment Protection and Biodiversity Conservation Act 1999 (EPBC Act) assessment
In November 2024, Hunter Gas Pipeline Pty Ltd referred the NLP Project to the federal 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 NLP to be a ‘controlled action’ requiring assessment and approval under the EPBC Act due to potential impacts on listed threatened species and ecological communities (sections 18 and 18A of the EPBC Act). The NLP 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 NLP EPBC Referral (2024/10050) decision is available on the Commonwealth EPBC Public Portal.
