Australia’s No Religion Surge Redraws a Christian Nation | Column

This is a column. Australia’s no religion population keeps rising, and the 2026 census now underway could confirm a decisive shift. The long trend points firmly in one direction.

In 2021, for the first time, fewer than half of Australians called themselves Christian, at 43.9%. Those choosing no religion reached 38.9%.

Why the no religion trend matters

The no religion share has climbed at every census. It stood at 22.3% in 2011 and 30.1% in 2016 before its sharp 2021 leap.

This is not simply locals drifting from church. Around a quarter of the non-religious in 2021 were born overseas, a fact that complicates lazy narratives.

Some critics do urge caution. One Sydney pollster argues the census may overstate the secular figure, putting it nearer 26%.

Even the sceptical number is striking. Between a quarter and two-fifths of a nation now claims no faith at all.

Humanist groups have pushed people to answer honestly rather than out of habit. Accurate data shapes school funding, chaplaincy and public ceremony.

The lesson reaches well beyond Australia. Across the English-speaking world, the non-religious are no longer a fringe but a plurality in waiting, a theme we explore in our coverage of secular rights.

A secular majority brings duties, not just numbers. It calls for a public life that treats belief and unbelief with equal respect.
