Scientists are urging major dam projects in NSW and Queensland be abandoned, warning of significant environmental and agricultural consequences.
ANU Professor Jamie Pittock, a member of the Wentworth group of concerned scientists, said he Wyangala dam proposal in NSW is expected to cost more than $2 billion dollars, with alternatives not properly explored.
"There are many alternatives to increase water security for all ... it can't be full to supply water and empty to catch a flood," Professor Pittock told a conference on Wednesday.
