Australia's population is now equal to that of the Indian city of Delhi, the where I shall be next month, however we have some 13 million to go to catch up to Tokyo; if that's any consolation.

And very shortly the demographic of Australia will be primarily Chinese. Look at the link below showing a map of Chinese in Sydney in 2011. And I reckon those figures have increased by about 25% since 2011.

Australia now is nothing more than a part of a Chinese mercantile system with China feeling free to dump its excess population and trade its crappy goods for land and resources.

Mr Opinion, are you related to Donald Trump? Nearly everyone else understands that migrants come here of their own accord rather than being sent by their government.

Yuyutsu, why do you consider nation building a threat? And what is it you think quality of live depends on other than standard of living?

Bazz, with solar panels ever cheaper, why do you think our energy production will decline?

When most Australians prefer to live in big cities, why do you equate increasing population with declining standard of living?

Why, when we have elections every 3 years, do you imagine there'd be a disorderly overthrow?

And have you failed to notice Australia's a rich country? Why do you think we won't be able to afford the basics?

Dear Aidan,

Time will tell. But I bet I am correct.

Every new person, whether they are born here or they immigrate here has an environmental impact. This is very serious, in terms of the Australian environment.

The link I have below, relates to Lord Howe Island - and is called "Plastic oceans".

I don't understand what people are going through (who move out of their home country due to "humans rights" issues), as I have never been through their day to day lifestyle, but standards of living (and limiting movement) are not helped by cutting foreign aid budgets for example.

The link is: http://www.abc.net.au/catalyst/stories/3583576.htm and I have seen it on television and is shocking to watch.

Aidan,

It's not what I think. It's what experts who know much more than I do have written. Given Australia's geography, and the fact that most people are crowded into the one third of the continent that is habitable, I am inclined to believe them. There are small countries with much smaller populations than ours doing much better than we are. Technology is fine; we just don't do it very well, and it will never overcome our inhospitible interior. We must face the fact that Australia is in serious decline, and more people is the last thing we need.
