Murray–Darling Basin Authority (MDBA), Media Release, 1 July 2026

New water trade arrangements under Schedule D of the Murray–Darling Basin Agreement will come into effect from 1 July 2026, following the completion of the Schedule D review and approval by Ministerial Council.

Murray–Darling Basin Authority (MDBA) Executive Director of River Management, Jacqui Hickey, said the updated arrangements are designed to make trade arrangements in the southern Basin clearer and easier to understand.

“These changes improve transparency around how trade decisions are made and give states more flexibility in how trade adjustments are managed,” Ms Hickey said.

“They also support more consistent trade opportunities across state borders and through The Narrows (previously referred to as the Barmah Choke).”

The amended Schedule D has been streamlined to make it more user-friendly and better able to keep pace with evolving market practices. It also includes simpler processes for reviewing and updating the rules when needed.

“The amended Schedule, Protocols and Procedures will commence on 1 July 2026, in line with the start of the new water year,” Ms Hickey said.
