Catholic Population

How many Catholics are there in Australia?

According to the 2016 Australian Census, the Catholic population was 5,291,817 or 22.6% of the total Australian population.

Between 2011 and 2016, the number of Catholics decreased, and the proportion of Catholics in the population also decreased. In 2011, the Catholic population was 5,439,267 or 25.3% of the total Australian population. In 2006, the Catholic population was 5,126,884 or 25.8% of the total Australian population.

Mass attendance

How many Catholics go to Mass on Sundays?

In 2011, about 662,000 people, or 12.2% of all Australian Catholics, attended Mass on a typical Sunday. We know from the 2011 National Church Life Survey that most people who attend Mass go every Sunday, so that the percentage of Catholics attending Mass at least once a month is just over 15%, only a little higher than the weekly figure.

In 2006, about 13.8% of Catholics attended Mass on a typical Sunday

Dioceses and Parishes

How many dioceses are there in Australia?

There are 34 dioceses in Australia. (A diocese is a section of the Church entrusted to the leadership of a bishop.) There are twenty-eight dioceses based on territorial divisions, five dioceses of Eastern Catholic Churches and one military diocese, where the bishop’s responsibility is the pastoral care of Catholic members of the Australian Defence Forces and their families.

How many parishes are there?

The 2018-19 Official Directory of the Catholic Church in Australia lists 1394, including 84 belonging to Eastern Catholic Churches.

What are Eastern Catholic Churches?

Almost all of Australia’s 5.3 million Catholics belong to what is called the Latin Rite or the Western Catholic Church, but there are also around 1.1% of Catholics who belong to Eastern Catholic Churches, often called Eastern Rites. The five largest Eastern Catholic Churches in Australia are the Maronite, Melkite, Ukrainian, Chaldean and Syro-Malabar, each of which has been established as a diocese (or eparchy), with a bishop (or eparch) who is a member of the Australian Catholic Bishops Conference. As well as these five Eastern Catholic Churches, there are also four others that have clergy resident in Australia. These are the Armenian, Syrian, Coptic and Russian Catholic Churches. There are probably Catholics belonging to other Eastern Rites as well, but they do not gather as distinct, organised Churches (Dixon 2005, p. 49).


How many priests are there in Australia?

The number of priests in Australia in 2018 was 2,900, made up of 1,861 diocesan and 1,039 priests belonging to religious orders (Official Directory of the Catholic Church in Australia 2018-19, p.795). (Diocesan priests belong to a locality called a diocese and are responsible to the bishop of the diocese or archdiocese, while religious order priests belong to groups such as the Jesuits, Franciscans or Salesians, and are responsible to the leaders of their order. There are about 40 orders of priests in Australia.)

How does this number compare with the past?

The number of priests in Australia peaked at 3,895 in 1971, and was above 3,800 from 1968 till the early 1980s. There has been a decline of around 25% since 1971.

What is the age profile of priests?

There is no complete profile on the age of Australian priests available. A 1996 study found that the average age of diocesan priests working in parishes was 56 years. Figures published by the Archdiocese of Melbourne, Australia’s largest diocese in terms of number of priests, showed that the average age of diocesan priests on appointment (i.e., not including retired priests) had risen from 44 in 1977 to 60 by 2001.

How many men are training to be priests?

In 2018, according to the Official Catholic Directory (p.296), there were 253 men training to be priests in Australia’s diocesan seminaries (i.e. not including those training to be religious order priests). In contrast, there were 546 in 1969. By 1991, that figure had dropped to 172, and then rose again in interceding years since, although fluctuates somewhat from year to year.

What is the ratio of Catholics to each priest in Australia, and how does that compare with the rest of the world? 

The 2018-2019 Official Catholic Directory shows that there were 1,825 Catholics for every priest in Australia. According to the 2015 Statistical Yearbook of the Church (p.109), the number of Catholics per priest by continent was as follows:

Africa 5,044
South America 7,118
North America 1,873
Asia 2,185
Europe 1,595
Oceania (including Australia) 2,164
World 3,091

Religious Sisters and Brothers

How many religious sisters and brothers are there in Australia?

The 2018-19 Official Directory of the Catholic Church in Australia records that there are 4,161 religious sisters and 679 religious brothers in Australia. In 2007, there were about 5,700 religious sisters and 1,020 religious brothers in Australia. The sisters belong to orders, or congregations, such as the Josephites (founded by Mary MacKillop), the Sisters of Mercy, the Sisters of Charity and many others. In all, there are just under 100 congregations of women religious in Australia and five congregations of brothers, including the Christian Brothers, the Marist Brothers and the De La Salle Brothers.
