Federal Labor has announced it will withdraw support for a major part of Murray-Darling Basin Plan, if elected.
Opposition spokesperson Tony Burke has announced that Labor would change the way in which 450 gigalitres of water is recovered by restoring the socio-economic definition for delivering water.
It comes less than a year after the Government and basin states agreed on a way to measure the socio-economic impact of recovering water.
Making the announcement with the South Australian state Labor Opposition in Adelaide, Mr Burke said Labor would also call an urgent review of the impact of climate change across the Basin.
