 The Archdiocese of Sydney is involved in many different agencies within Sydney to provide services, care and support to people in need, including aged care; education; health care; prayer, worship and liturgy; solidarity and justice; vocations and seminary; youth and young adults ministry.In 1819, two priests were officially authorised by the British government to minister to the Catholics of the Australian colony.Until 1834, the territory of the entire Australian mainland (including what is now the Archdiocese of Sydney) and the island of Tasmania was a distant outpost of the Vicariate Apostolic of Mauritius.
