I too have long been suspicious of Australia's "Official" population of 26 million. More like 30 Million - and maybe even a lot more. Nothing other a than gut feeling though - except to say I've done a lot of interstate travel over the last 15 years and can't help but notice the massively accelerated growth in that short time alone. I have no doubt successive governments have let in way more people than they would care to acknowledge. You can also add illegal arrivals/over-stayers into the mix, which would also be a huge problem.
