Evidence given at last week's Senate Inquiry into the Murray Darling Basin has proved the futility of South Australian Premier Mike Rann's High Court challenge to unblock Victoria's 4pc cap on water trade, says South Australian Liberal Senator, Mary Jo Fisher.
"Expert witness, Professor Mike Young, told us that water brokers know how to trade around the 4pc cap," Senator Fisher said.
"Does Mike Rann know what's happening in the water market?
"What's the point spending 18 months and taxpayers' money trying to circumvent a trading cap that traders are already circumventing?"
She said High Court action would do more harm than good and that COAG needed to resolve the issue another way.
