In 1982, the Archdiocese began the [[St. Andrew's Greek Orthodox Theological College (Sydney, Australia)|St Andrew's Greek Orthodox Theological College]] in Sydney as a part of the School of Divinity of the University of Sydney. Archbishop Stylianos currently serves as the dean of St. Andrew's, while Bishop Seraphim serves as sub-dean. As the lone Orthodox Theological College in Australasia, it often accepts students of other jurisdictions. Approximately 100 students have graduated from St. Andrew's since its inception; of these, about 25 have been ordained as clergy, while others have become teachers in the Churches schools, catechists, chanters, or have continued into postgraduate studies. Under the auspices of the College is the [[Greek Orthodox Archdiocese of Australia Byzantine Music School]], where students of the college and any other interested laity may learn Byzantine chanting in Greek.

[[St. Basil's Homes (Australia)|St. Basil's Homes for the Aged]], operate around Australia in each capital city since 1969 caring for all needs of the aged in their numorous facilities as well as delivering care into the homes of the Greeks under community care programs. St. Basil's cares for about 1200 aged Greeks in Australia. In 2006 St. Basil's commissioned a new $30million state of the art facility in Miranda to the south of Syndey.
