Some ideas.
1 Water harvesting from air, depending on viability.
Welcome back, Zarkov.
Lights pipe, Im not Zarkov.
Neutrino isn’t. I am.
Easy solution. Get water for the Murray-Darling from the Warragamba Dam. The Hunter River water is extremely under-utilised so use the Hunter River water as an extra water supply for the Sydney-Newcastle-Wollongong conurbation freeing the water from Warragamba Dam for diversion into the Murray-Darling basin.
Further north, the Clarence River is also extremely underutilised so transfer some of that into the Murray-Darling.

we are harvesting water form the icecaps.. we just have to wait.
Yes. Wait for climate change.
Climate change is a double plus for Murray-Darling water supply.
Firstly, climate change in Australia is that the SW of the country (including Adelaide) gets drier. And the SE of the country including the Murray-Darling gets wetter.
Secondly, increrasing atmospheric CO2 means that in order for plants to grow through photosynthesis they need to keep their stoma open for a smaller fraction of the time. Lower stoma opening time means that transpiration is reduced and as a result there is less water loss and the plants grow just as well or better on a lower water supply. This has already been observed on the Murray-Darling basin with irrigated crops requiring less water than they used to, of order 35% less water.
The water problem with the Murray-Darling is actually due to houshold water use. Household water use because of increased population has increased enormously since the 1970s, use of water in irrigation has decreased over the same period, and water for unirrigated crops has pretty well held steady. So fix that by slowing the growth of cities on the Murray-Darling, or insist on greywater recycling in those cities.
