What is a water announcement?

A water announcement is information that is reasonably likely to have a material effect on the price or value of a Murray-Darling Basin water access right. Water announcements are defined in section 12.49 of the Basin Plan 2012 water trading rules and include:

  • allocation announcements
  • private carryover  announcements
  • any other public announcement from the Minister that may have a material effect on the price or value of a water access right.

The South Australian Minister publishes water announcements in the South Australian Government Gazette and in media releases.
