Within Australia the church hierarchy is made of metropolitan archdioceses and suffragan sees. Each diocese has a bishop, while each archdiocese is served by an archbishop. Australia has two living members of the College of Cardinals: the previous Archbishop of Sydney, George Pell and Edward Idris Cassidy. The national assembly of bishops is the #AustralianCatholicBishopsConference (ACBC) headed by Mark Coleridge, the Archbishop of Brisbane. There are a further 175 autonomous Catholic religious orders operating in Australia, generally affiliated under Catholic Religious Australia, headed by Sr Monica Cavanagh RSJ.
The church in Australia has five provinces: Adelaide, Brisbane, Melbourne, Perth and Sydney. There are seven archdioceses: Adelaide, Brisbane, Melbourne, Perth, Sydney, Canberra and Goulburn, and Hobart. It has thirty-five dioceses, comprising geographic areas as well as the Australian Defence Force and dioceses for the Chaldean, Maronite, Melkite and Ukrainian rites. There is also a personal ordinariate for former Anglicans which has a similar status to a diocese. In 2017, there were an estimated 3,000 priests and 9,000 men and women in institutes of consecrated life and societies of apostolic life.
