Catholic Church: the largest Christian denomination in Australia
The Catholic Church is the largest Christian denomination in Australia, with a culturally diverse membership of around 5 million people, or about 20% of the country's overall population, according to the 2021 ABS Census data. This makes it a larger group than those with Anglican affiliations, who made up 9.8% of the population in 2021.
The Catholic Church has played a prominent role in welfare and education in Australia since colonial times. It is the largest non-government provider of these services in the country. Catholic Social Services Australia aids 450,000 people annually, and the St Vincent de Paul Society has 40,000 members, making it the largest volunteer welfare network in Australia. In 2016, the church had 760,000 students in more than 1,700 schools.
The church in Australia has five provinces: Adelaide, Brisbane, Melbourne, Perth, and Sydney. It has 35 dioceses, including geographic areas, the military diocese, and dioceses for the Chaldean, Maronite, Melkite, Syro-Malabar, and Ukrainian Rites.
The Catholic population in Australia is aging, with a median age of 43, compared to 33 in 1996 and a median age of 38 for all Australians. The church community is also shrinking and becoming more culturally, linguistically, and ritually diverse. In 2021, 1,369,744 Australian Catholics (21.4% of the total number) were born abroad in a non-English-speaking country, and 21.5% speak a language other than English at home. The Philippines, Italy, India, Vietnam, and Croatia are the top five countries supplying non-native English-speaking Catholics.
Since 1996, Eastern Catholics in Australia have been counted separately from Latin Catholics. In 2023, of the 5 million total Catholics in the country, 77,393 (1.5%) registered as belonging to the Eastern Catholic Churches. However, the actual number of Eastern Catholics in Australia is likely higher, as some may have simply ticked the standard "Catholic" box in the census.

Catholics: older, more culturally diverse
Australia is home to a significant number of Catholic Christians, and as of 2021, they make up about 21.87% of the country's population. This equates to roughly 5,468,444 people. While the Catholic Church has a strong presence in Australia, one notable aspect of this religious group is its diverse and unique demographic composition when compared to other Christian denominations or the general population.
One key characteristic of Australian Catholics is their older age profile. On average, Catholics tend to be older than the general population, with a higher median age. This is partly due to the fact that Catholicism has a long-standing historical presence in Australia, with many Catholics having deep familial roots in the country's Catholic community. Additionally, the Catholic Church has been successful in retaining its older members, which contributes to the higher median age. This is in contrast to other Christian denominations, which often have a younger demographic.
The cultural diversity within the Catholic community is another distinguishing factor. Australian Catholics are a diverse group, with a significant proportion being first or second-generation Australians. Many Catholic migrants have come from countries with strong Catholic traditions, such as Italy, Malta, Vietnam, and the Philippines. This has contributed to the cultural richness within the Australian Catholic Church, with various ethnic groups bringing their own traditions and practices, adding to the multifaceted nature of Australian Catholicism.
The impact of this cultural diversity can be seen in the variety of Catholic practices and rituals observed. For example, the celebration of Mass may incorporate different languages and cultural traditions, reflecting the backgrounds of the congregation. This diversity also extends to Catholic schools and community groups, fostering a sense of inclusivity and representing the multicultural nature of modern Australia.
In addition to their older demographic and cultural diversity, Australian Catholics also tend to be geographically concentrated in certain areas. There are higher proportions of Catholics in some states and territories compared to others, with New South Wales and Victoria having the largest Catholic populations. Furthermore, within these states, there are often pockets or suburbs with higher concentrations of Catholics, reflecting the historical settlement patterns of migrant groups and the establishment of Catholic parishes and communities.
While Australian Catholics share a common faith, their community is diverse and multifaceted, reflecting the broader Australian society. The older demographic and cultural diversity within the Catholic Church contribute to its unique character and play a role in shaping the religious landscape of the nation. Understanding these characteristics provides insight into the complex and varied nature of religious affiliation and practice in Australia.

Catholic organisations: providers of social welfare and education
According to the 2021 ABS Census data, there are approximately 5,075,907 Catholic Christians in Australia, representing about 20% of the country's overall population. It is the largest Christian denomination in the country, with a culturally diverse membership.
The Catholic Church in Australia has a long history of providing social welfare and education services to the community. It is the largest non-government provider of these services in the country. Catholic Social Services Australia (CSSA), for instance, aids around 450,000 people each year, while the St Vincent de Paul Society has 40,000 members, making it the largest volunteer welfare network in Australia.
Catholic organisations in Australia have been involved in social welfare since colonial times. For example, Catholic laywoman Caroline Chisholm helped single, migrant women and rescued homeless girls in Sydney. Today, Catholic organisations continue to provide a range of social services, including residential aged care and job support. Other notable Catholic welfare organisations in Australia include Centacare, CatholicCare, and Caritas Australia, which is the international aid and development organisation of the Catholic Church in the country. Caritas Australia works with vulnerable communities to address issues such as poverty, injustice, and disaster relief.
Catholic education in Australia has its roots in the 18th century and has grown to become the second-largest provider of school-based education in the country, after government schools. As of 2018, around one in five Australian students attend Catholic schools, with 777,000 students enrolled in 1,755 schools as of 2018. The Catholic Church has established primary, secondary, and tertiary educational institutions, including notable schools such as Loyola College Watsonia, Saint Ignatius' College, and Xavier College. The administrative oversight of these schools varies, with Catholic systemic schools under the supervision of parishes, dioceses, or archdioceses, while religious institutes oversee Catholic independent schools, and Catholic universities are administered through academic senates.

Catholic affiliation: in decline, with more reporting 'no religion'
According to the 2021 ABS Census data, there are 5,075,907 Catholic Christians in Australia, representing about 20% of the country's overall population. This makes Catholicism the largest Christian denomination in the country. However, there is evidence of a decline in Catholic affiliation in Australia, with a growing number of people reporting no religious affiliation.
Historically, the Catholic Church in Australia has had its roots in the Irish minority during early colonial times. Over time, it has grown to become the country's largest Christian denomination, with a culturally diverse membership. Despite this growth, there are indications of a decline in religious affiliation among Australians, particularly within the Catholic Church.
In recent years, Australia has become more religiously diverse, with an increasing number of people affiliating with religions other than Christianity. While Christianity remains the most common religion, it has seen a decrease of more than 1 million people in its followers. Almost 10 million Australians reported having no religion in the census, indicating a shift towards secularism or spiritual beliefs that do not adhere to specific religious doctrines.
The decline in Catholic affiliation is not limited to Australia; it is also evident in other countries, such as the United States. In the US, each successive generation has fewer Catholics than the previous one, and the number of people with no religious affiliation continues to grow. This trend is particularly pronounced in certain regions, such as the Northeast, where Catholic identification has decreased significantly.
The decline in religious affiliation is attributed to various factors, including generational change. Younger generations, such as Gen Z and millennials, are more likely to have no religious affiliation or identify with non-Christian religions, such as Islam. Additionally, the increased secularization of society and the impact of the ongoing coronavirus pandemic may also contribute to the decline in religious affiliation and church membership.
In conclusion, while Catholicism remains a significant religious denomination in Australia, there is a noticeable decline in affiliation. This trend mirrors a broader shift towards secularism and religious diversity, as more people report having no religion or identify with other faiths. The decline in Catholic affiliation is not unique to Australia and is part of a global trend, particularly in Western countries like the United States.
