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
Dampier Bunbury Pipeline | AGIG - Australian Gas Networks
Dampier Bunbury Pipeline WA’s strong and diverse resource industry has positioned the State front and centre in the economic landscape of Australia. Both natural gas and the pipeline play an important role in the State’s economy, providing the energy many major mining and resources customers need to power their operations.

The Dampier to Bunbury Natural Gas Pipeline (DBNGP) is a transmission pipeline owned and operated by Dampier Bunbury Pipeline (DBP). DBP is part of the portfolio of companies that form Australian Gas Infrastructure Group (AGIG). AGIG is owned by various consortia of Hong Kong-based entities listed on the Hong Kong Stock Exchange.
- Who owns the Dampier to Bunbury Natural Gas Pipeline?
- The Dampier to Bunbury Natural Gas Pipeline (DBNGP) is a transmission pipeline owned and operated by Dampier Bunbury Pipeline (DBP). DBP is part of the portfolio of companies that form Australian Gas Infrastructure Group (AGIG). AGIG is owned by various consortia of Hong Kong-based entities listed on the Hong Kong Stock Exchange.
- 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.
- When was the Bunbury Gas Pipeline built?
- Construction began in 1982 and was completed in 1985 with the pipeline being extended to Bunbury. The SECWA as well as funding the construction of the pipeline also had the foundation contract for the supply of gas. The DBNGP was also developed with the support of Alcoa as its initial cornerstone customer.
- 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 does DBNGP stand for?
