Australia: Orthodoxy fastest growing church amidst general Christian decline

Ștefana Totorcea | 16 July 2022

The Orthodox Church is the fastest growing Christian denomination in Australia according to recently published 2016-2021 census data.

The Greek Orthodox Church is the fasting growing of all in Australia, while the Serbian and Antiochian Churches are also in the top 10.

The Greek Church grew by 17,400 members, the Serbian by 7,300, and the Antiochian by 4,400. However, the number of Australians who identify simply as “Christian,” without specifying a Church or denomination grew by 76,100.

The Orthodox growth comes amidst an overall decline in Christianity in Australia. In 2016, 12.2 million people (52.1%) identified as Christian, but this number fell to 11.1 million (43.9%)by 2021, though Christianity, in general, remains the most popular religion in Australia.

By far the largest decline was suffered by the Anglican church, followed by the Catholic church, though the Maronite and Chaldean Catholic churches are in the top 10 for growth. 8 of the 10 fastest-growing groups come from Eastern Christian traditions.

Romanians in Australia number approximately 25,000 people and those in New Zealand number around 3,000. They are organized in the Diocese of Australia and New Zealand.

Since you are here…

…we do have a small request. More and more people visit Orthodoxy and the World website. However, resources for editorial are scarce. In comparison to some mass media, we do not make paid subscription. It is our deepest belief that preaching Christ for money is wrong.

Having said that, Pravmir provides daily articles from an autonomous news service, weekly wall newspaper for churches, lectorium, photos, videos, hosting and servers. Editors and translators work together towards one goal: to make our four websites possible -,, and Therefore our request for help is understandable.

For example, 5 euros a month is it a lot or little? A cup of coffee? It is not that much for a family budget, but it is a significant amount for Pravmir.

If everyone reading Pravmir could donate 5 euros a month, they would contribute greatly to our ability to spread the word of Christ, Orthodoxy, life's purpose, family and society.
