Additionally, in 2016, another 0.5% instead opted to specify their form of irreligion, writing it under "other," hence resulting in 30.1% of Australians (or just over 7,040,700 people) selecting "no religion.
In a 2004 worldwide study by Pippa Norris and Ronald Inglehart, 25% of Australians stated they do not believe in any gods.
[16] The book was prompted by the disparity between Australia's increasing secularism and the increasing political and educational influence and funding of religion in Australia and contains essays by 33 authors (including Leslie Cannold, Robyn Williams, Tim Minchin, Graham Oppy, Philip Nitschke, Ian Hunter, Lyn Allison, Russell Blackford and Ian Robinson) on atheism-related topics in areas including history, law, education, philosophy and neurobiology.
Critic and commentator Robert Hughes stated "Any Australian political candidate who declared their God was on their side would be laughed off the podium as an idiot or a wowser (prude, intrusive bluenose).
"[17] Conversely, Australia has had many openly atheist or agnostic political figures elected to high positions, including prime ministers Gough Whitlam (whose philosophical position has been called "post-Christian"[18]) John Curtin, John Gorton, Bob Hawke and Julia Gillard.
It supports the separation of church and state and removing religious prayers, rituals, and bias from government and public institutions and their documentation, and abolishing blasphemy laws.
[23] Although many Australians identify themselves as religious, the majority consider religion the least important aspect of their lives when compared with family, partners, work and career, leisure time and politics.
[25] In explaining this phenomenon, writer and broadcaster Paul Collins said "Australians are quietly spiritual rather than explicitly religious" and the prominent historian Manning Clark defined Australian spirituality as "a shy hope in the heart ... understated, wary of enthusiasm, anti-authoritarian, optimistic, open to others, self-deprecating and ultimately characterized by a serious quiet reverence, a deliberate silence, an inarticulate awe and a serious distaste for glib wordiness.
[37] Norman Morris, the company's communications director, noted that the change in religious affiliation could indicate a growth of atheism and agnosticism, or a move away from identification with organised Christianity by theistic believers.
He identified possible causes for the change, including "morally conservative religious doctrines" contrasting with progressive attitudes on abortion, same-sex marriage, the use of condoms in the global fight against the HIV pandemic.
[38] A 2008 global Gallup poll found nearly 70% of Australians stated religion as having no importance,[39] much higher than their American counterparts and on par with similarly secular countries such as Japan, the Netherlands, Finland and France.
Only a few Scandinavian countries (Norway, Sweden, Denmark) and post-Soviet states (Estonia) are markedly less religious.
A 2008 Christian Science Monitor survey of 17 countries reported that youth from Australia and the United Kingdom were the least likely to observe religious practice or see any "spiritual dimension" to life.
[21] A 2009 survey of 1,718 Australians conducted by NCLS research found that 61.5% say that "religious faith or spirituality" was of little or no importance to career and lifestyle decisions.
[44] A 2011 report by the American Physical Society claimed that religion may die out in Australia and eight other Western world countries.
[52] A 2009 Christian Research Association survey of 1,718 Australians concurred, finding that 16% attended a religious service at least once a month, down from 23% in 1993.
[6] A study in 2011 by the Christian Research Association discovered that the attendance of Uniting churches has declined by 30% over the previous 10 years.
The association's president, Philip Hughes, has predicted that the decline in church attendance would continue "at least for the next 20 years".
The study also found that the average age of people attending Catholic and Anglican churches is around 60 years.
