Putting water buybacks back on the table during the current flood crisis is a highly cynical move by the federal government, says Nationals Mallee MP Anne Webster.
The federal Water Minister Tanya Plibersek has again raised the issue of buybacks, to recover the 450 gigalitres of environmental water, under the Murray Darling Basin Plan.
But Ms Webster said the detail was hidden behind a veil of "commercial sensitivity".
"Mallee growers deserve more transparency and respect from their federal government," Dr Webster said.
"With so much water around currently the average person isn't necessarily worried about the potential lack of it, but that doesn't mean we can allow Labor to quietly push through these measures that will break the local horticulture industry."

Australian Table Grape Association chief executive Jeff Scott said he feared the economic impact of buybacks returning to the water market.
"As soon as you take water off the market, it affects the market value," Mr Scott said.
"With a reduction in supply but the same or higher demand, the price goes up - which hurts our growers."
Robinvale grower Tony Natale said buybacks would be devastating to the market, driving up prices.
"There is already insufficient water to supply all the licenses ... it's going to make it even scarcer," he said.
Sunraysia Table Grape Growers Association secretary-treasurer Domenic Sergi, Red Cliffs, said the prospect of buybacks being introduced came at a difficult time for growers and did nothing but shift the problem.
"It's kicking the can down the road, in any other industry if there's a problem they'd manage the environmental issues and find an engineering solution for it," Mr Sergi said.
"This is basically an easy way of saying I'm not going to take responsibility for it I'm just going to reduce the size of the industry.
"It's like saying if we were running out of electricity, rather than finding solutions around that you just start telling businesses to shut down - it's no different."
Dr Webster said the government had been warned previously about the impacts of buybacks on regional communities.
'That's why the Nationals introduced the socio-economic test for any buybacks and as expected, no additional water could be purchased for environmental purposes because communities would be negatively impacted," Dr Webster said.
"The government needs to learn from history, last time water buybacks were instituted it resulted in a Swiss cheese of horticultural properties when farmers sold off their water and left dry paddocks.
"The burden for water infrastructure for remaining properties to pass those dry paddocks fell to farmers - this is not something we want to revisit."
