The next release of seasonal trade opportunity from the Goulburn to the Murray system is 10.00 am on 15 December 2022. This follows the previous 17 October trade opportunity that was cancelled due to the emergency response to flooding across northern Victoria. It will also be the final Goulburn to Murray trade opening of the water year.

It is estimated that approximately 58 GL of Goulburn to Murray trade opportunity will become available at this time. This total includes the volume of trade opportunity that would have been released in October.

The Goulburn to Murray trade rule applies to allocation trade from the Goulburn, Loddon, Campaspe and Broken systems to the Victorian Murray and interstate.

This trade opportunity is highly competitive. To manage expected demand for the 15 December 2022 opening, there will be some changes to how allocation trade applications are processed.

The key change is that, on 15 December 2022, allocation trade applications will be processed manually by each relevant water corporation. Automatic processing will not take place.

This will be implemented as follows:

  • All applications submitted via the MyWater and Broker Portals from 9:00 am to 10:30 am on 15 December 2022 will be manually processed after 11:00 am. This includes within-zone trade.
  • The Goulburn to Murray trade opportunity balance will be updated at 10.00am on 15 December 2022.
  • Between 10.00 am and 10.30 am, water market participants should submit all allocation trade applications through the MyWater and Broker Portals as usual. Each trade application will continue to be queued in the order received by our online interface in the Victorian Water Register.
  • After 10.30 am, the MyWater and Broker Portals will be offline until 5:00 pm 15 December 2022 while manual processing of applications takes place.
  • Applicants will receive notification on the outcomes of trade applications as they are manually processed, and no later than 5:00 pm 15 December 2022.
  • The system will return to normal operation at 5:00 pm 15 December 2022.

Due to these changes, during the 30-minute application submission window (10.00 am – 10.30 am), the available Goulburn to Murray trade opportunity balance on the where can I trade map and Water Market Watch App will not change, as applications will not be automatically processed and assessed in real time. The balance displayed during the 30-minute submission window will remain at the total opening volume. This should be taken into consideration when you submit your application.

Once manual processing begins at 11.00 am, trade application notification emails will be sent as each application is completed in turn, and the remaining Goulburn to Murray trade balance on the where can I trade map and Water Market Watch App will update accordingly.

The volume of trade opportunity released on 15 December is based on the following:

  • Observed water use in the Torrumbarry Irrigation Area from 1 July 2022 to 30 November 2022 relative to the long-term historic average water use from 1 July to 30 November.
  • Any reduction in the Goulburn reserves, due to spill, that were quarantined at the start of the water year.

Torrumbarry Irrigation Area water use up to 30 November 2022 is around 10 GL, which is around 12% of the long-term average up to 30 November. These are indicative volumes based on the best available data to date. The trade opportunity on 15 December 2022 may differ slightly from these estimates.
