Also what are you going to do to stop the salt water contaminating the underground fresh water, there is already a problem around Perth.

Some highlight costs and how much water it takes to be useful
Surely the costs today balanced against future benefits are quite small.
In fact job creation and decentralization are benefits that alone make it worth while
The future if we wait ,costs will be far more
But the changes in just our lifetimes should remind us turning water inland one day should be very easy

Philip S,
Fyi, freshwater floats on saltwater so it is a no-brainer that flooding Lake Eyre with seawater which will cause precipitation which in turn will collect & store from the surface down.
Also, once the lake is flooded for some time & a new local weather pattern has established it may even be possible to shut off the link to the sea.
This needs to be looked at with a long-term view not from an investor mentality view of invest this morning & expect a profit in the afternoon. The whole project would literally pay for itself by the infrastructure itself. Housing, roads & industry requirements will in no time create a huge boost to the economy at no environmental damage.

There is zero chance of any scheme happening, so there's no point in getting worked up about it. The last big one was the Snowy Mountains and there is absolutely no chance that anything like that will be seen again. Those were the days when immigration of people who actually wanted to work occurred, and there was no fixation with environmental issues. Money was cheaply available. Now, money is not available, and the type of immigrants we get are not coming here to work - or not very hard, anyway. It's non-productive jobs or, for to many, welfare. There is no work ethic, no pride and values left in Australia. We are more interested in the gender of politicians than we are in in the quality of politicians. Globalisation has made us too soft and weak to do anything not approved by the corrupt United Nations, or by some fly-bitten country because it is the-largest-Muslim-country-in-the-world. Our educational standard 39th out of 41. Australia is rooted.

I grabbed a globe and placed a drop of water on the Northern Territory. It quickly ran down hill toward NSW.

We just need to scale it up.

This whole country is screwed;
Nothing but incompetence and a total failure to develop policies beneficial to the nation.
The whole system needs to be completely overhauled and re-evaluated.
The system isn't built to benefit the people anymore.
