Review of RAB-based irrigation prices 2027–29

On 30 October 2025, the Queensland Government directed us to investigate and report on appropriate prices for the irrigation services provided by Sunwater and Seqwater, derived using the regulatory asset base (RAB) approach. These prices are to be based on allowable costs that are consistent with our positions from the review of irrigation prices for 2025–26 to 2028–29, adjusted to reflect the use of the RAB approach for recovering renewals expenditure.

We have published a stakeholder guidance paper to explain our planned approach to the review and to help Sunwater and Seqwater in preparing their proposals, which are due to us by 27 February 2026.

We will begin our formal consultation process after we receive the businesses’ proposals. We encourage interested parties to subscribe for email updates on this project here.
