Opposition Leader Anthony Albanese said a very-fast train should be a no-brainer. He told The Sydney Morning Herald conference on population and settlement that Australians’ quality of life will become worse unless we deal with public transport.

The Coalition virtually junked Federal funding for public transport when it came to power in 2013. It moved it to roads and airports. The only rail it is interested in is the inland rail to move freight to and from their mates’ farms.

State Governments are struggling to deal with the consequences.

The NSW Minister for Planning, Rob Stokes, pointed out that Sydney is at the mercy of the Federal Government’s immigration quotas which are usually determined by Treasury’s desire to ensure GDP growth no matter what.

Stokes wanted population, settlement and planning not to be driven by Treasuries.

He said: “What we should not do is use population as a political football. Nor should we use a population increase as a lazy proxy for economic growth. Ultimately, the growth that matters is expanding the capacity, choice and opportunity for every Australian, wherever they live, rather than a focus on growing our population for its own sake.”

He is misguided here. Governments in Australia have never “focused on growing our population for its own sake”. In the immediate post-war early years of immigration we increased population for security reasons. “Populate or perish” was the mantra.

By about 1980 Australia’s population had a pleasant cultural mix and the economies of scale were such that we had probably reached peak benefit and we really did not any deliberate immigration program.

By then, however, the big businesses that profited most from high immigration, especially those who made windfalls by rezoning land, did not want it stopped. Indeed they wanted it increased and the then Prime Minister John Howard, in the thrall of his big-business benefactors, turned on the tap, and in effect lost control of Australia’s borders.

And now, as this week’s conference and an earlier meeting of planning ministers revealed, politicians and big business will continue to put the cart before the horse. “We must spend more on infrastructure to deal with the congestion and pressure caused by population growth,” they squeal.

What about the more obvious plea: “We must reduce population growth so we do not have to desperately scramble to keep up with infrastructure demands?”

We know why: the profits and power of the donors to the major parties coupled with a fear that anyone who wants to reduce immigration will be branded a racist.

But if that high population growth is the given, several things will flow. First is overall lower living standards. The mantra of Australia having had the longest period of continuous economic growth in history and therefore we are better off is bunkum. The headline figure is misleading propaganda peddled by governments.

The real test for economic well-being is GDP per person (per capital GDP). If you account for Australia’s astonishingly high population growth, we have been in recession for the past year with falling per-capita GDP compounded by growing inequality.

If you take further account for the reduction in quality of life with congestion and environmental damage the reduction in living standards is even worse.

Secondly, we will have to change the way we do transport, as state governments of both complexions well know.

We are going to have to collectivise more. Shock, horror. People will not be able to take their own half a tonne of steel with them on every city journey. Many people will not able to store a car in the big cities. The land cost will be too high. We will have to move to more sharing, electric and even autonomous vehicles.

We will have to develop a fast train network between Melbourne-Canberra-Sydney-Brisbane and even Adelaide and much more light rail in cities. Interest rates are very low. Governments should stop worrying about the surplus and invest while conditions are good: cheap capital and available labour.

Yes, we need roads, but they have to connect to efficient public transport. Roads and tollways on their own will not do it. They are too costly and just get clogged as soon as they are built because of the inherent inefficiency of cars.
