On TV coverage of the floods we can sebe tempory levees being built, surely the time has come for more permanent levees and associated infrastructure, to protect our towns and people.
Australia is a rich country, richer than Holland and look what that country has achieved with levees (dykes).

Tamworth, NSW, has fine examples of levees.

I'm ambivalent about levees...

"If it keeps on raining, levee's going to break
If it keeps on raining, the levee's going to break
When the levee breaks, have no place to stay"

OTOH during the last drought...
"Drove my Chevy to the levee but the levee was dry". But, given I and the good ole boys were drinking whiskey and rye, I could be mistaken.

We should build not only levees but dredge the main
river systems to restore the depth of flow. All floods
contain silt in the water system which clogs up the
river systems. As an example - Port Philip Bay in
Victoria has the main shipping channels dredged on a
regular basis to insurance the required depth for
shipping. We need to do the same with our rivers to
insure a continuous large volume flow of water so they
don't flood.

Surely the time has come to replace our moronic politicians and bureaucrats with people who will do what is needed to deal with events that have been occurring regularly for more than two centuries.

"Should we build more levees in flood prone areas?"

Well, who's the we here?

If it's the Australian population as a whole that has to pay for it, then NO.

If it's the Local Community- especially those people who decided to buy/build on a flood plain- then YES.

Why should people who are smart enough not to live in known flood zones have to cough up money for those who choose to buy/build in a such an area?

Thinkabit just think a bit, there’s a good chap.
