Overview
AGIG launched commercial operations of the 440km Tanami Gas Pipeline in February 2019. The 8-inch line delivers 13TJ/day to two power stations servicing Newmont’s Tanami gold mine.
Detailed engineering and design
From late 2017, our in-house engineering team led pipeline design and calculations, covering five key facilities: the inlet meter near the Amadeus Gas Pipeline, two scraper stations, and custody transfer meter stations at Granites and Dead Bullock Soak.
Heritage, environmental and land management approvals
AGIG’s in-house land team secured key agreements with the Central Land Council (CLC), including Indigenous Land Use Agreements (ILUAs) and Section 19 deeds across Aboriginal freehold land, ensuring heritage protection through extensive cultural surveys. Legal and access teams negotiated compensation and land access with pastoralists, minimising disruption and offering income opportunities. Environmental approvals—handled internally with expert support—were completed within 10 months, enabling timely project commencement.
Construction and commissioning
Construction began with easement marking, fence relocation, and right-of-way (ROW) clearing. Line pipe was transported from Darwin. Built under harsh desert conditions, the project was delivered safely on time, and within budget.
Practical completion
Practical completion after commissioning the Tanami Gas Pipeline was achieved by February 2019, and Newmont's power stations are currently taking gas.
