Many assertions are being made about Australia’s rates of immigration and population growth, but it’s hard to find a coherent discussion of the issue. There’s not just an elephant but a menagerie of ignored creatures lurking around the living room.
The elephant in the middle of the room is the cost to society of ‘durable assets’ for each new person, imported or home-grown. Durable assets include not just infrastructure like roads, trains, water and electricity but houses, shops and schools. That cost is sensibly estimated by sustainability researcher Jane O’Sullivan to be around $500,000 per person. Some of that cost is public, borne by governments, and some is borne by the private sector.
