Western Australia - Developing our future plans for the Dampier Bunbury Natural Gas Pipeline (1 January 2026 to 31 December 2030)

Our Final Plan for the Dampier to Bunbury Natural Gas Pipeline has been submitted to the ERA who have now published and it is publicly available on their website.

This Final Plan sets out our business plan for the five year period commencing 1 January 2026 and will enable us to continue to deliver strong safety and reliability performance delivered over AA5.

Our Final Plan proposes a price of $2.45 per GJ (Full Haul Equivalent, $December 2024), which is slightly below the indication of price we provided on 10 December 2024 of $2.48 per GJ. As we have discussed during the course of our engagement, the single largest driver of the price increase from AA5 has been the increase to interest rates. This has seen the rate of return increase from the historic lows in AA5 of 3.54% to 6.93% in AA6.

Our proposed capital expenditure and operating expenditure allowances are $288 million and $652 million respectively, each uplift on current AA5 spend reflecting the higher cost environment and scope of work we plan to undertake in AA6.

We believe we have prepared a Final Plan that has taken into account the feedback you have provided to us over the past 18 months and has been developed consistent with our stated ‘no surprises’ commitment. We consider that our plan has been informed by and delivers for our customers, and as such, is capable of being accepted.

We will continue to engage with you over the course of the ERA review process and look forward to continuing our discussions during 2025. We welcome the opportunity to meet with you directly to discuss the Final Plan and your feedback.

We thank you for contribution to the engagement process resulting in the development of our Final Plan.
