I think the real problem is that the growth has improved the economy but reduced the quality of life. A few decades ago it was affordable for most families to buy a nice house close to the beach. Now the big cities have doubled in population and quadrupled in price, that is no longer achievable. Yes Australia could easily have 100m people living there, but they wouldn't be as comfortable as when there were 15m. Its a bit like California. LA & SF in the 60s and 70s sounds dreamy - and we'll never get back to there.
