Scheduled to be held on Tuesday and Wednesday, respectively, early morning fog prevented inquiry members from flying into the region to attend.
The Legislative Assembly Committee on Investment, Industry and Regional Development has suggested the hearing would now be held in either July or August.
The inquiry will look at the impacts of Federal Government imposed water reforms on regional NSW.
In particular, it will look at the Water Amendment (Restoring Our Rivers) Act 2023 which includes further water buybacks as a form of recovering water for the environment.
The inquiry is being chaired by Independent Member for Barwon Roy Butler.
Other inquiry panel members are Liberal Party member and Member for Albury Justin Clancy, Richie Williams from The Nationals and Labor members Stephen Bali (deputy chair), Charishma Kaliyanda, Warren Kirby and Maryanne Stuart.
The inquiry received 101 submissions earlier this year.
Some of the groups who submitted submissions were invited to speak at the Deniliquin and Griffith meetings, along with others who did not make a formal submission.
Those on the Deni schedule included Murray River Council, Edward River Council, Western Murray Land Improvement Group, Yanco Creek and Tributaries Advisory Council, Southern Riverina Irrigators, Murray Irrigation Limited, NSW Irrigators’ Council, Deniliquin Business Chamber, Murray Regional Strategy Group, NSW South-West Water Users Association and Sefton & Associates Pty Ltd.
