The results of the last Australian census are trickling out, and the results offer an insight into the changing concepts of contemporary Aussies.
In 1966 only 0.8 % marked 'No religion' on their census form.
In 2001 those marking 'No Religion" had grown to 16%.
And in 2016 those marking 'No Religion" had grown to 29.6%.
So more non-believers than any other group. Catholics (the previous largest group) were now only 22.5% of Australians.

The other interesting change is language,
Of course, English remains the most spoken language at home- 2016 - 72.7% of the population, but the second most spoken language (Mandarin Chinese) is now 2.5% (against 1.6% in 2011) reflecting a major change in the ethnic background of Australians.
