Apparently from after the census this year, we will be identifiable. In the past the census was anonymous which led to honest answers because it was never connected to you as an individual. Our government promises that the census information connected to you will not be used against you. But our unknown governments of the future cannot promise any such thing.
What a perfect census this would be for a Hitler type.
So therefore I will just lie on the census form and risk prosecution. I will be a old single working man living in a a cheap rented flat with a minimal income. At a minimum, just watch the number of gay couples in Australia drop immensely.
I urge you to do the same and very obviously corrupt the information so the Australian Bureau of Statistics realises the error of its way.
The census provides invaluable information for a multiplicity of government departments, organisations and far too many places to list. It's reliability is about to be wrecked for no good reason.
