High immigration is changing the Aussie way of life


In between scandalising over the invading hordes of boat people, John Howard greatly increased the immigration intake after the turn of the century, and this has been continued by the later Labor and Coalition governments. “Net overseas migration” accounts for about 60 per cent of our population growth.

In 2000, the Australian Bureau of Statistics projected that our population wouldn’t reach 25.4 million until 2051. We got there this year. Our population is growing much faster than other developed countries’ are.

The growth in our economy has been so weak over the past year that they’ve had to stop saying it, but for years our politicians boasted about how much faster our economy was growing than the other economies.

What they invariably failed to mention was that most of our faster growth was explained by our faster-growing population, not our increasing prosperity. Over the year to June, for instance, real gross domestic product grew by (a pathetic) 1.4 per cent, whereas GDP per person actually fell by 0.2 per cent.

That’s telling us that, despite the growth in the economy, on average our material standard of living is stagnant. All that immigration isn’t making the rest of us any better off in monetary terms.

Of course, that’s just a crude average. You can be sure some people are better off as a result of all the migration. Our business people have always demanded high migration because of their confidence that a bigger market allows them to make bigger profits.

Economists, on the other hand, are supposed to believe in economic growth because it makes all of us better off. They’re not supposed to believe in growth for its own sake.

This week one of the few interest groups devoted to opposing high migration, Sustainable Population Australia, issued a discussion paper that’s worth discussing. It reminds us that many of the problems we complain about are symptoms of migration.

The biggest issue is infrastructure. We need additional public infrastructure – and private business equipment and structures, and housing – to accommodate the needs of every extra person (locally born as well as immigrant) if average living standards aren’t to fall.

Taking just public infrastructure – covering roads, public transport, hospitals, schools, electricity, water and sewage, policing, law and justice, parks and open space and much more – the discussion paper estimates that every extra person requires well over $100,000 of infrastructure spending.

When governments fail to keep up with this need – as they have been, despite a surge in spending lately – congestion on roads and public transport is just the most obvious disruption we suffer.

The International Monetary Fund’s latest report on our economy says we have “a notable infrastructure gap compared to other advanced economies”. Spending is “not keeping up with population and economic growth”. We have a forecast annual gap averaging about 0.35 per cent of GDP for basic infrastructure (roads, rail, water, ports) plus a smaller gap for social infrastructure (schools, hospitals, prisons).

One factor increasing the cost of infrastructure is that about two-thirds of migrants settle in the already crowded cities of Sydney and Melbourne – each of whose populations is projected to reach 10 million in the next 50 years, with Melbourne overtaking Sydney.

According to a Productivity Commission report, “growing populations will place pressure on already strained transport systems. Yet available choices for new investments are constrained by the increasingly limited availability of unutilised land”.

New developments such as Sydney’s WestConnex have required land reclamation, costly compensation arrangements, or otherwise more expensive alternatives such as tunnels. It’s reported to cost $515 million a kilometre, with Melbourne’s West Gate Tunnel costing $1.34 billion a kilometre.

Who pays for all this? We do – one way or another. “Funding will inevitably be borne by the Australian community either through user-pays fees or general taxation,” the commission says.

Combine our growing population with lower rainfall and increased evaporation from climate change and water will become a perennial problem and an ever-rising expense to householders and farmers alike.

The housing industry’s frequent failure to keep up with the demand for new homes adds to the price of housing. And the only way we’ll double the populations of Melbourne and Sydney is by moving to a lot more high-rise living.

High immigration is changing the Aussie way of life. Before long, only the rich will be able to afford a detached house with a backyard.
