Senator ROBERTS (Queensland) (14:31): The Murray-Darling Basin Plan has driven farmers to a class-action lawsuit against the Murray-Darling Basin Authority, seeking damages of $750 million. Last Thursday, 4,000 farmers protested on the banks of the Murray at Tocumwal against their water being sent to South Australia for, as some people say, recreational flows. They even threw an effigy of Minister Littleproud into the river. How much stronger does the opposition need to be before the minister pauses or kills the plan?
