The Dampier to Bunbury Natural Gas Pipeline (DBNGP) is the longest natural gas pipeline in Australia. It is 660mm in diameter, which also makes it one of Australia's largest in terms of transmission capacity. At the time of its commissioning in 1984,[2] it was one of the longest gas pipelines in the world.[3]
The pipeline runs within Western Australia from a point near Withnell Bay, on the Burrup Peninsula near Dampier, to Bunbury in the south-west of the state. It carries natural gas, most of which enters the pipeline at the domestic gas plant associated with the North West Shelf Venture project. The other main inlet point is approximately 135 km south of Dampier, where one of the sales gas pipelines from Varanus Island Processing Hub connects with the DBNGP. In June 2008, following a pipeline rupture and explosion at the Varanus Island facility, the DBNGP carried additional volumes of gas from the North West Shelf plant to the south-west of the state, for a period of several months.

As a single trunkline it is 1530 km long,[4] extending from the Burrup Peninsula in the Pilbara region, to Bunbury in the south west of Western Australia. It supplies gas to industrial, commercial and residential customers in Perth and major regional centres along the pipeline route. It is covered by Western Australian pipeline licence PL-40. A number of lateral pipelines are connected to this pipeline, most of which are covered by separate licences, although PL-40 itself covers the main trunkline and some laterals totalling a length of 1789 km.[2]
