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.

Find out more about how the Goulburn-to-Murray trade opportunity is calculated. DEECA have also produced frequently asked questions about the limit and worked examples. 

• 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, through My Water or the Broker Portal. An application submitted at the start of the window has the same chance of success as one submitted at the end.
• After the submission window closes, DEECA will undertake a randomisation process to determine a processing order of the applications, in the presence of an Australian Competition and Consumer Commission (ACCC) independent observer.
• All Victorian trade applications will be referred to manual processing from 7 am Monday 15 December until the completion of randomisation.
• Goulburn to Murray trade applications will be referred to manual processing from 7 am Monday 15 December until the conclusion of processing on Tuesday 16 December 2025.
• The My Water and Broker Portal will be briefly offline on Tuesday 16 December once manual processing is complete (approximately half an hour). Normal Register operations will then resume. The timing of this outage, once known, will be announced on the Victorian Water Register news.

Please note the following important application eligibility criteria:

• For any one seller ABA, the total volume submitted (whether singly or via multiple trade applications) for consideration into the randomisation process cannot exceed the volume of tradable allocation available in that ABA at the start of the submission window (7 am, 15 December 2025).
• If an increase in seasonal allocation is announced on 15 December after 7am, this will not increase the total volume eligible for inclusion in the randomisation pool for this trade opening.
• Applications to ‘trade remaining balance’ will be deemed ineligible for the randomisation pool.
