So in a nutshell - PM Turnbull initially said Snowy 2.0 would cost $2Bn - then in dribs n drabs over years the price doubled, trebled, quadrupled - now it is said to cost $12Bn yes Twelve Billion $Kangaroos
I expect the final cost could be north of $20Bn.
And then it will still be an unproductive dog of a waste of taxpayers money.
