Alan Kohler is speaking a very different tune on immigration now that Labor is in power. Under the Coalition, immigration had to be cut. But under Labor, lower immigration is suddenly risky.
Water is an inconvenient truth that population boosters continue to ignore.
"The federal government's Big Australia mass immigration policy poses the greatest threat to Australia's water supply".

It's pretty basic supply and demand analysis, Cameron. Population growth shot up in the mid 2000s when NOM more than doubled, and construction didn't rise to match.
@EricCrampton
Nice strawman. Nobody is calling to "ban immigration". But it needs to be commensurate with housing supply, infrastructure, water supplies, environment, etc. The past 20 years have been way past that level
@FelixTLucas
Seeing as you are so fixated on population growth rates, Australia's 2.5% rate is about five times advanced nations' 0.5% and the highest since 1952.
@EricCrampton
Leaving aside massive upfront costs, the running costs of desalinated water depend on the cost of energy. Energy is expensive down East Coast Australia. So, the cost of desalination will also be expensive.
@FelixTLucas
Why not? Why should immigration forever rise? Do you believe in exponential growth? The natural environment is impacted by population numbers, not growth rates. The same applies to water supply. Growing the nation's population by a Canberra or more every year is batshit crazy.

Why must immigration rise with population growth? That would create a vicious circle of immigration->bigger population->more immigration->bigger population. It would mean exponential growth.
The environment and water supply doesn't care about growth rates. It cares about numbers.
