99% of the snowy water goes down the Murray so u will have to fight those ppl for that water ,Lake Eucumbene the biggest snowy hyrdo lake it is under 30% it hasn`t been full for 15 years , we do not have enuff power to run a desalinisation unless we build a nuke plant , RAIN is the only answer
It dosen`t matter if it rains in Wollongong or Sydney as all that water goes down the storm water into the ocean , it needs to rain inland
