Regulated Asset Base (RAB)

Overview

In mid-2025, the Queensland Government set irrigation prices for 2025-26 and 2026-27. However, it postponed setting prices for 2027-28 and 2028-29 while it further considered a regulated asset base (RAB) methodology for renewals recovery. A review into RAB has now begun.

Sunwater will submit a proposal to the QCA in February 2026. This will inform irrigation prices for the period from 1 July 2027 to 30 June 2029.

Information sessions

Sunwater customers are invited to attend online information sessions about the RAB Irrigation Price Review in November 2025. Visit this page for details and to RSVP for one of these sessions.

Sunwater will also provide an update at the Customer Advisory Committee meetings scheduled for the rest of 2025.

If you have questions or feedback about the RAB Irrigation Price Review, please contact us by email on customerengagement@sunwater.com.au or phone 13 15 89.

Survey

Irrigation customers will be sent a short survey in early December seeking views on timeframe options for closing annuity balances if a RAB approach is adopted.

To help customers understand how the RAB approach will impact pricing, and to inform responses to the survey, Sunwater has prepared an Irrigation Customer Invoice Calculator relevant to specific tariff groups in service contracts.
