The next Goulburn-to-Murray trade opening is scheduled for Monday 15 December 2025. Based on current estimates, a minimum of 14 gigalitres (GL) of Goulburn-to-Murray trade opportunity will be released.

The estimated minimum 14 GL of trade opportunity is an indicative volume based on the available data to date. It does not include additional opportunity that may be available on 15 December following the Northern Victorian Resource Manager’s seasonal outlook announcement at 10 am. This additional opportunity can arise due to adjustments to the Legacy Trade Reserve set aside to meet historic exchange rate trade commitments.

The Goulburn-to-Murray Trade Limit – which governs allocation trade from the Goulburn, Broken, Campaspe, and Loddon systems to the Victorian Murray system, New South Wales, and South Australia – will open again on Monday 15 December 2025. This is the third of three Goulburn-to-Murray scheduled trade openings for the 2025–26 water year. Estimated volumes will be made public closer to this date.

  • Applications for the Goulburn-to-Murray trade opportunity should be submitted during the submission window, between 7 am and 2 pm on Monday 15 December 2025.
  • During the submission window, water market participants should submit trade applications through My Water or the Broker Portal, and all trade applications during this period will be queued for later processing.
  • After the submission window closes, DEECA will undertake a randomisation process to determine a processing order of the applications, in the presence of an ACCC independent observer.
  • Processing of applications, in the order determined by the randomisation process, will occur as soon as possible after randomisation.

Customers are encouraged to lodge trade applications throughout the 7-hour submission window. Market participants are not required to submit trade applications as soon as the submission window opens. A customer who submits a trade application at the start of the submission window will have the same chance of having their application succeed as a customer who submits at the end of the window.

The Department of Energy, Environment and Climate Action has released the Goulburn-to-Murray Post Trade Opening Report (October 2025). This report summarises the outcomes from the October Goulburn-to-Murray trade opening. It consolidates information available via the Victorian Water Register website with some additional data around the number of unique allocation accounts that traded. It provides insights into the number, volumes, and reason for trade for all applications submitted and the order they were processed.

The October Goulburn-to-Murray trade opportunity opened with a balance of 31,523 ML. A total of 203 eligible trade applications were received, with a total volume of 70,222 ML. Eligible applications were randomised to determine a processing order. Processing resulted in 98 applications being approved.

The Goulburn to Murray trade review Scientific Advisory Panel (the Panel) has prepared three reports, covering detailed results and analysis of the lower Goulburn River Research and Investigations Program undertaken during 2023–24, and interpretation of the outcomes over the combined three years from the start of the program (2021–24).

The program is designed to assess the environmental performance of the long-term Operating Rules for the lower Goulburn River and to determine whether the rules are working as intended to prevent environmental damage from sustained high flows over summer and autumn.

Climatic and flow conditions throughout 2021–24, including record breaking floods in spring 2022 and summer 2024, saw relatively low demand for inter-valley trade (IVT) deliveries from the Goulburn River to the River Murray during the peak irrigation period (December to April).

Earlier this year, the Department of Energy, Environment and Climate Action (DEECA) and WaterNSW developed a draft framework to assess options for improving the efficiency and equity of access to inter-valley trade opportunities. In July–August 2025 we sought feedback on whether the draft framework is appropriate and what options for managing access to trade opportunities should be assessed.

A report, summarising what we heard during the consultation, is available on Engage Victoria.

Help us improve the efficiency and equity of access to inter-valley and inter-zone water allocation trade opportunities in the southern Murray-Darling Basin.

The Department of Energy, Environment and Climate Action (DEECA) and WaterNSW have developed a draft framework to assess options for improving the efficiency and equity of access to inter-valley and inter-zone trade opportunities. We are now seeking community feedback on whether the framework is appropriate for achieving this purpose, as well as your ideas on options for managing access to trade opportunities that should be assessed in the next stage of this project.

You can view the draft framework and submit your feedback to DEECA via a brief questionnaire at EngageVic. Alternatively, you can also submit your feedback to WaterNSW. This joint consultation will be open until 17 August.

From 1 July 2025 there are additional Australian Government obligations on water brokers and exchanges operating in the Murray-Darling Basin, under a new Water Markets Intermediaries Code.

As a water market participant you are encouraged to familiarise yourself with the Code and the new safeguards that have been put in place to ensure your broker acts in your best interests.

The new Code, and complementary trust accounting obligations, place further responsibilities on water market intermediaries. This is in addition to the rules they must follow under Australian Consumer Law.

The Code is designed to give greater protection to users of water brokers and exchanges, aligning standards with those that exist in other similar markets. Some obligations under the Code commence on 1 July 2025, others on 1 October 2025.

On Wednesday 2 July 2025, the Murray-Darling Basin Authority made 38,767.7 megalitres (ML) of allocation trade opportunity available from above to below the Barmah Narrows. As in previous years, there was more demand than supply.

2025 marked the third year that Victoria and New South Wales (NSW) synchronised the timing of the Barmah trade opportunity.

This year, Victoria and NSW implemented a new joint randomisation protocol for the processing of Barmah trade applications. The new protocol meant that differences in each state’s processing approach and systems did not influence traders’ access to the available Barmah trade opportunity. You can learn more about how the protocol worked here.

The Department of Energy, Environment and Climate Action (DEECA) would like to provide an update about the upcoming July 2025 trade openings.

In response to consistently high demand during key trade events, in October 2024, the Victorian Water Register (VWR) temporarily moved to a randomisation approach rather than ‘first in, first served’ for the Goulburn to Murray trade openings. The approach reduces load on the VWR during the trade opening and ensures the opportunity is reliably made available to all market participants.

Following a review of these processes, DEECA will continue to use a randomisation approach for all Goulburn to Murray trade openings of 2025. Additionally, in partnership with WaterNSW, a joint randomisation process will be implemented for the 2025 Barmah trade opening.

Other smaller trade openings, including the Broken trade out limit (made available in July each year), will continue to operate without change. This is because the impact on reliable service delivery from the VWR isn’t as large as Barmah and Goulburn to Murray trade openings.

DEECA thanks users who provided feedback on the randomisation approach. A summary of feedback provided will be included in our next information update.

Read more: July 2025 Trade Openings update

In October 2024, DEECA implemented a new randomisation processing approach for the October and December Goulburn to Murray trade openings. The approach was designed to provide market participants with reliable access to those trade openings as soon as possible.

DEECA is now reviewing how those openings went and seeking feedback from market participants on the trade application process and the randomisation approach. Market participants wanting to provide feedback to DEECA on the new approach can do so using this feedback form.

Submit-feedback

DEECA is now also working with its WaterNSW counterparts to deliver a reliable Barmah trade opening in July 2025. We are currently considering using a combined ‘single queue’ and randomisation process for applications for the 1 July Barmah trade opportunity. This would leverage the approach that Victoria used in the Goulburn to Murray trade openings last year and extend this so that it applies to applications received by both WaterNSW and the Victorian Water Register.

Both DEECA and WaterNSW are committed to working together to ensure reliable access to this year’s opening Barmah trade opportunity and a unified experience for customers from both Victoria and NSW.
