What Hunter Gas Pipeline does
Hunter Gas Pipeline (HGP) is an Australian proprietary limited company (HGP Pty Ltd) operating as a wholly-owned subsidiary of Santos Ltd following Santos's acquisition in August 2022. HGP is developing an 833-kilometre underground natural gas transmission pipeline designed to connect the Wallumbilla Gas Supply Hub in Queensland to NSW southern markets, providing a second competitive route to domestic gas and addressing energy security as coal-fired power stations close. A companion sub-project, the approximately 55-kilometre Narrabri Lateral Pipeline, will connect the Santos-owned Narrabri Gas Project to the HGP main line and is currently progressing through EPBC assessment and public EIS exhibition (November-December 2025).
The pipeline infrastructure is built to the AS2885 standard using epoxy-coated high-strength steel line pipe at nominally 508mm (20 inch) diameter, buried at 750-1800mm depth within a 30-metre easement inside a 200-metre approved corridor. The system is engineered hydrogen-ready, requiring only approval modification to transport hydrogen as energy-transition demand evolves. Stage 1 construction commenced in December 2023, and the asset carries multi-jurisdictional planning approvals (NSW project approval February 2009, Queensland Pipeline Licence PPL124, EPBC referral decision December 2008) plus a portfolio of construction environmental, traffic, noise, and water management plan sign-offs.
HGP's business model centres on usage-based transmission fees for transporting natural gas from Queensland supply to NSW demand, complemented by transaction-fee gas supply to regional commercial customers through designed offtake points at towns along the route. End customers span electricity generators (for baseload and peaking power and to firm variable renewables), industrial and manufacturing users, residential households, and regional commercial businesses. The pipeline is contracted to transport 100% of Narrabri gas to the east coast domestic market and, once fully operational, is sized to supply more than half of NSW daily gas demand. As a Santos subsidiary, HGP does not disclose standalone revenue, with commercial pricing negotiated directly with shippers and offtake partners rather than published.

Hunter Gas Pipeline product offering
Product offeringCore offering
Hunter Gas Pipeline operates a proposed 833-kilometre underground natural gas transmission pipeline connecting the Wallumbilla Gas Supply Hub in Queensland to NSW markets, providing a second supply route for Queensland gas. The system includes the Hunter Gas Pipeline (HGP) mainline plus a ~55-kilometre Narrabri Lateral Pipeline connecting Santos's Narrabri Gas Project to the HGP, with regional offtake points enabling gas supply to local industrial, commercial, and residential customers along the route. The pipeline is engineered to be hydrogen-ready for future energy transition use.
Product overview
Hunter Gas Pipeline operates as a gas transmission infrastructure network consisting of two primary pipeline systems: the Hunter Gas Pipeline (HGP), an 833-kilometre underground pipeline connecting Queensland to NSW, and the Narrabri Lateral Pipeline (NLP), an approximately 55-kilometre pipeline connecting the Narrabri Gas Project to the HGP. Both pipelines use epoxy coated high strength steel line pipe with approximately 508mm diameter and are designed to transport natural gas, with provisions for hydrogen transportation during the energy transition.

Hunter Gas Pipeline competitors and assessment
Company assessmentDirect peers
- APA Group: APA Group is Australia's largest natural gas infrastructure business, operating transmission and distribution pipelines across the country. It is the closest direct comparable to HGP as a long-haul natural gas transmission pipeline operator, and competes for the same NSW/Queensland gas transportation contracts.
- Jemena: Jemena owns and operates the Eastern Gas Pipeline and other gas transmission assets across eastern Australia. It is a directly comparable natural gas transmission operator whose pipeline network serves the same NSW market that HGP targets, and is effectively HGP's primary incumbent competitor on the Queensland-to-NSW corridor.
- ATCO Australia: ATCO Australia operates natural gas transmission, distribution, and storage infrastructure, including pipelines in Queensland that connect to the same Wallumbilla Gas Supply Hub that anchors HGP. It is a directly comparable gas infrastructure peer in the eastern Australian gas network.
- Australian Gas Infrastructure Group (AGIG): AGIG operates multi-state gas transmission and distribution networks across South Australia, Victoria, Queensland, and NSW. It is a directly comparable gas pipeline infrastructure operator with overlapping customer segments in regional gas supply and pipeline transportation services.
- Multinet Gas: Multinet Gas owns and operates gas distribution networks in Victoria, serving residential, commercial, and industrial customers. It is a directly comparable gas pipeline operator within the broader Australian east-coast gas market where HGP supplies wholesale gas.
Broad incumbents
- AGL Energy: AGL Energy is Australia's largest electricity generator and a major gas retailer with significant gas-fired generation exposure. It is a broad incumbent in the Australian gas/electricity market and a key potential offtaker of HGP gas for power generation as coal plants close.
- EnergyAustralia: EnergyAustralia is a major Australian electricity generator and gas retailer, with gas-fired generation assets in NSW. It is a broad incumbent in the Australian energy market and a potential industrial-scale offtake customer for HGP gas in the NSW region.
- Origin Energy: Origin Energy is one of Australia's largest integrated energy companies with upstream gas production, generation, and retail operations. It is a broad incumbent in the Australian gas value chain and a potential offtake customer for HGP-transported gas through its generation and retail businesses.
- Woodside Energy: Woodside Energy is a major Australian energy company with upstream gas and LNG production. While not a pipeline operator, it is a broad incumbent in Australian gas markets and would be a comparable large-cap energy counterparty for HGP's industrial and electricity-generation customers.
Others
- Snowy Hydro: Snowy Hydro is an Australian energy generator and retailer with major firming capacity. It is thematically related to HGP as a provider of firming and energy security in the NEM, and a potential counterpart for gas-fired peaking capacity supplied via HGP, though it does not itself operate gas pipelines.
