Thanks Hasbeen for your feedback. Especially from what I understand about your engineering background. I get the idea that pushing the water back to the coast when that is where the water is being dumped is problematic along with the dynamics of the coastline. Usually I find that the storms don't hit Brisbane directly because of the topology around Brisbane- it's based in between mountains- so it tends to go north and south. Gympie does get cut off and split in half on major events. This is why I thought that pushing the water inland might be a better solution- the GDR seems to be a bit spotty and might offer an option similar to what Individual is suggesting- though I'm not sure of the cost of the pipe idea. St George can be particularly dry and also relatively flat til Toowoomba. Thanks again Hasbeen.

Woke up to an early morning thunderstorm in Brisbane. Only light rain, so all's good.

Something funny; watching the TV coverage of the floods when the studio anchor girl, asked the reporter on the spot. " Are they still expecting high tide at 8.30 tonight?"

What did she think ssomeone has control over the time of the tide.

Anchor girl; Jason are they still expecting high tide at 8.30 tonight?

Reporter; Nah Catrina, King Canute has been down and he's moved it to midnight.

Anchor girl; All those poor wet souls bobbing about in the water, our hearts go out to them.

Hasbeen,
The water over your property is simply insane ! 4 metres on flat ground. No amount of engineering can be of use in such conditions.
Looking at Lismore & all the other flooding around Brisbane on TV left me speechless.
Those poor people who lost everything must be helped at once. A national emergency levy must be introduced immediately & any insurance company baulking should have their assets impounded

Indy,

How do you propose a "national emergency levy" should work? Through taxation, who pays, and who don't? How is it operated, given Morrison's track record, money for marginal Coalition seats, bugger the battlers.

Individual,
So the solution to the millions of hectares of land affected by rising salt is to irrigate with fresh waster?
I’m sure that the CSIRO will be happy to know that.

Is Mise,
of course it can't be done if people who don't want it done put up every hurdle they can think of.
I'm totally confident inland Australia can be made as fertile as it once was with the help of people who want to better things not revel in status quo !
