The Diocese of Goulburn was established in 1863. At that time it extended to the south and west of Goulburn to the south-western corner of New South Wales (south of the 34th degree of latitude). In 1883 the diocese was divided, with the western portion designated as the major part of the newly created Diocese of Riverina. In 1950 the name was changed to the Diocese of Canberra and Goulburn. St Saviour's Cathedral, the mother church of the diocese, is located in Goulburn, New South Wales. Both the diocesan bishop and the diocesan office are located in Canberra, ACT, Australia's national capital, which is 87 kilometres to the south of Goulburn.
