Dampier Bunbury Pipeline | AGIG - Australian Gas Networks
During DBP’s ownership, $1.7bn has been invested into the DBNGP in meeting the energy needs of Western Australia, via separate expansion projects, Stages 4, 5A and 5B. As a result of these projects the pipeline capacity was increased by 60% with the pipeline now being 83% duplicated or “looped”.
Access Arrangement for period 2025-2025 - Economic Regulation
On 1 April 2025, the ERA published its final decisions on the proposed revised access arrangement for the Dampier to Bunbury Natural Gas Pipeline. The ERA did not approve DBP’s proposed changes to the access arrangement and published a revised access arrangement and access arrangement information. ERA revised Access Arrangement Final Decision

About DBP | AGIG - Australian Gas Networks
Dampier Bunbury Pipeline (DBP) is the operator of the privately owned Dampier to Bunbury Natural Gas Pipeline (DBNGP), Western Australia’s most important energy infrastructure asset.
- Who owns Dampier Bunbury Pipeline?
- Epic Energy owned and operated the pipeline for six years, eventually selling the pipeline in October 2004 to Dampier Bunbury Pipeline (DBP) Ltd, which is the trading name of the DBNGP group of companies. DBP had two institutional shareholders: D.U.E.T. (Diversified Utilities and Energy Trusts) (80%) and Alcoa (20%) up until 2017.
- Who uses the DBNGP pipeline?
- The majority of the natural gas transported by the pipeline is consumed by major industrial users in the mining and minerals processing industries, but it also supplies gas to power generators and gas retailers. The DBNGP was constructed in stages between 1982 and 1985 by the State Energy Commission (SECWA).
- Should DBP adopt a pipeline design based on a gas composition?
- Kimber Consultants recommends that DBP should adopt a pipeline design that is based on a gas composition implied in the Recommended Design Gas Composition as shown in Table 4, which has a combination of the lowest expected heating value, a low Wobbe index, no LPG and modest levels of inerts.
- What happens if DBP chooses a high quality gas specification/composition?
- Conversely, if DBP chooses a high quality gas specification/composition and lower quality gas is shipped, then the pipeline’s increased capacity will be “under-designed” and DBP will not have the pipeline capacity to sell as a firm service and will incur penalties; and the incremental tariffs will not result in cost recovery – a double loss.
- What is the longest natural gas pipeline in Australia?
- The Dampier to Bunbury Natural Gas Pipeline (DBNGP) is the longest natural gas pipeline in Australia. It is 660 millimetres (26 in) in diameter, which also makes it one of Australia's largest in terms of transmission capacity. At the time of its commissioning in 1984, it was one of the longest gas pipelines in Australia.
- When was natural gas introduced into the DBNGP?
- Natural gas was introduced into the pipeline in 1984 when the first stage stretching from Dampier to Kwinana Junction was commissioned with throughput of about 240 TJ/d. In 1985 the pipeline was extended to Bunbury. The DBNGP has been in continuous operation ever since.
