The population statistics have little meaning to the mainstream population when expressed as a national aggregate. A figure of 35 million or 50 million for the whole of Australia may sound small or large. This is reflected in the contradictory results of The Age/Nielson poll.
It is important to first appreciate the inherent weaknesses of statistics and of survey sampling of quantitative data.
Australia’s population size has a comparable meaning as world population being about 6.7 Billion. The mainstream will ask, so how does that impact on me? How do people evaluate whether a figure is acceptable or too large?
Well, when that figure is expressed as a relative change or is translated to the scale of the person being surveyed. For instance, If Australia’s population in November 2009 is about 22 million, then 50 million represents a doubling of the current figure. In order to objectively guage public opinion about projected population growth and immigration, the Age/Nielson poll ought to ask is: Is the doubling of Australia’s population from what it is now to what it may be in forty years time an acceptable level of population growth? This allows the respondent to a survey assess the figure relative to what they know now. It is important to be aware that population growth and immigration, while related, are different statistics.
Further, the national figure should be translated into a likely proportion on a State basis (which in Australia would in the main be the same as the Capital City of that State. For instance, NSW (or Sydney) may typically have a third the population of Australia (see ABS statistics below). So another survey question could ask: Is an increase of Sydney’s population by 13 million (1/3 of 40 million) an acceptable level of population growth?

Yes, we must question the validity of the poll – the collection, analysis and interpretation of the population data. The statistical method used by Age/Neilson should be independently peer scrutinised, to ensure best practice is followed and so the public and federal policy makers alike are not mislead with inappropriate findings. “Statistics is the science of making effective use of numerical data relating to groups of individuals or experiments. It deals with all aspects of this, including not only the collection, analysis and interpretation of such data, but also the planning of the collection of data, in terms of the design of surveys and experiments.”

I question whether in this poll whether indeed effective use has been made of the numerical data.
Sure sign Brisbane's population has exceeded regional saturation
It's a sure sign Brisbane's population has reached saturation when new dams are proposed.
If a city cannot sustain its population on the existing resources it has, then it has reached population saturation.
Brisbane's metropolis now sprawls from NSW to Noosa Heads and west of Ipswich. It's population demand for water has exceeded its water supply.
Queensland Premier Bligh says "the Queensland Government will have to come up with alternative sources of drinking water if the Traveston Crossing dam in the state's south-east is not approved." [ABC 10-Nov-09]
Water is just one public utility, then there is electricity, gas, public transport, education, housing, aged care, etc. All Queensland public services are overstretched from Rudds flood gate policy on immigration with spill over effects from interstate as many thousands flee saturated Sydney and Melbourne to a bulemic Brisbane. Australia's urban population problem is snowballing, yet Rudd blindly cannot see the elephant in the room or has a hidden agenda. It has nothing to do with race and nothing to do with the refugee issue - which are being mischieviously played as political red herrings.
Traveston dam on the Mary River near Gympie will be another travesty of justice on the existing rural community way of life and ecology to feed an insatiable sprawl policy.
Garrett stands to be remembered for his watering down of Australia's environmental legislation and for species extinctions on his watch.
