Regarding New Dams & Natural Climate Change.
When will Ideology revert to Common Sense?

ONLY ~1% of all Water is as both a liquid & in potable form, there NOT being any guarantee that such will fall into the "lap of Humanity". Humanity does need to show its supposed intellect & process that greater Water Mass to garner that little it does need from the Oceans (0.0014)x(10exp24) kilograms (approx.) of otherwise Saline Water.

(Slide of Surface during Last Ice Age)

HUMANITY has become used to a distribution of Water as seen over the past centuries, but this situation is the rarity, the exception of Nature. The period of the past 15,000 years is presenting the ‘melt’ of the rising Climate after a Global Glacial Event (an “Ice Age”).
SPECIES have been going extinct within these periods well before Humanity even existed in its “Modern form”, & it is entirely possible still that Humanity could suffer if Ideology is given any further treatments preferentially over known Science. Within the platformed 'greenhouse doom & woe' rhetoric there is this danger if such is continued to be heeded.
IT is that Desalination is needed to protect both the Natural Flows of Fresh Liquid Water and those others species reliant on such. Humanity can & must source such requirements form the growing Saline Waters expected for the oncoming Climate Period still within its Natural Expectations of overall behavior. Then perhaps there will not be needed action by Humanity to otherwise meddle with natural flows presented within & to Nature (in a wider sense). It is that the weather patterning alterations (linked to Surface treatment within Human activity) is being noticed & makes further Dams only expensive lobby appeasements...

IT is that now is again ‘that time’ in this Planets “Geo-Bio History” that species have been placed under stress, with now following a ~200 Million year long Climate 'Primary Crest' behavior sequence & now being a period presenting recurring Glaciations.

NOTICE in the slide "Four Periods of Glaciation" (figure 2.) the Permian position within that previous (blocked) Period of recurring glaciations to the "Present" (far right of time line) then notice the extract quotes of readily available Science, extracted from "The Carboniferous Ice Age" (with due thanks to the authors for their wording):-
--
["Following the Carboniferous Period, the Permian Period and Triassic Period witnessed predominantly desert-like conditions, accompanied by one or more major periods of species extinctions."]
--
["Earth's atmosphere today contains about 380 ppm CO2 (0.038%). Compared to former geologic times, our present atmosphere, like the Late Carboniferous atmosphere, is CO2- impoverished! In the last 600 million years of Earth's history only the Carboniferous Period and our present age, the Quaternary Period, have witnessed CO2 levels less than 400 ppm. There has historically been much more CO2 in our atmosphere than exists today. For example, during the Jurassic Period (200 mya), average CO2 concentrations were about 1800 ppm or about 4.7 times higher than today. The highest concentrations of CO2 during all of the Paleozoic Era occurred during the Cambrian Period, nearly 7000 ppm -- about 18 times higher than today. The Carboniferous Period and the Ordovician Period were the only geological periods during the Paleozoic Era when global temperatures were as low as they are today. To the consternation of global warming proponents, the Late Ordovician Period was also an Ice Age while at the same time CO2 concentrations then were nearly 12 times higher than today-- 4400 ppm. According to greenhouse theory, Earth should have been exceedingly hot. Instead, global temperatures were no warmer than today. Clearly, other factors besides atmospheric carbon influence earth temperatures and global warming."]

["Basically, Earth undergoes alternating periods of ice ages and warming whenever a continuous continental landmass extends from one polar region to the other while at the same time there exists a large polar continent capable of supporting thick ice accumulations. These conditions existed 300 million years ago during the Carboniferous Period as they do for the Earth today. However for most of geologic history the distribution of the continents across the globe did not satisfy this criteria. Continental drift continually rearranges the continents, moving at rates of only a few centimeters per year. We are actually in an ice age climate today. However for the last 10,000 years or so we have enjoyed a warm but temporary interglacial vacation. We know from geological records like ocean sediments and ice cores from permanent glaciers that for at least the last 750,000 years interglacial periods happen at 100,000 year intervals, lasting about 15,000 to 20,000 years before returning to an icehouse climate. We are currently about 18,000 years into Earth's present interglacial cycle. These cycles have been occurring for at least the last 2-4 million years, although the Earth has been cooling gradually for the last 30 million years."]
--
["Today the Earth warms up and cools down in 100,000- year cycles. Geologic history reveals similar cycles were operative during the Carboniferous Period. Warming episodes caused by the periodic favorable coincidence of solar maximums and the cyclic variations of Earth's orbit around the sun are responsible for our warm but temporary interglacial vacation from the Pleistocene Ice Age, a cold period in Earth's recent past which began about 2 million years ago and ended (at least temporarily) about 10,000 years ago."]

THERE isn't going to be enough potable water overall (let alone in Australia), even if Humanities “overall Population” does shrink. Certainly there is going to be a further Natural rise is relative Sea Level, whilst naturally melting Ice will not present that melt volume into the Potable category of Liquid Water, the increase will be in Saline Water.
DESALINATION of Water in Australia is no longer disputable as an immediate necessity, needed well before Recycling (you cannot 'recycle' nothing) or any further Dams (you cannot catch what does not fall) projects are built when needed is protection against that declining overall “potable water” percentage.

• It is that Climate Change is real & Natural, still displaying its natural progessions; the falsehoods are within the Greenhouse Rhetoric and its now “attached” lobby platforms.
