Bishop Anthony Gerard Percy was born in Sydney in 1963 and grew up in Cooma, NSW, after his family relocated there in 1966. The second of six surviving children of Joan and John Percy, he was educated at St Patrick’s Primary School and Monaro High School in Cooma, before completing his secondary education at St Joseph’s College, Hunters Hill.
Before entering the priesthood, Bishop Percy earned an Honours degree in Finance from the University of New South Wales. He then entered St Patrick’s College, Manly, to undertake seminary formation, and was ordained a priest for the Archdiocese of Canberra and Goulburn in 1990 by Archbishop Francis Carroll.
His early ministry included appointments to St Mary’s Parish, Young, and the parishes of Queanbeyan, Ardlethan, Barellan, and Ariah Park. In 1999, he commenced doctoral studies in Washington, D.C., completing a Doctorate in Sacred Theology in 2003, specialising in Catholic social teaching—particularly the role of private property and private initiative in serving the common good.
Upon returning to Australia, Bishop Percy was appointed Parish Priest of Goulburn, NSW, where he contributed significantly to the restoration of the historic Sts Peter & Paul’s Old Cathedral, the world’s only greenstone cathedral.
In 2008, he was appointed Rector of the Seminary of the Good Shepherd, Homebush, at the request of George Cardinal Pell, a role he held until 2014. He returned to the Archdiocese of Canberra and Goulburn as Vicar General in 2015, serving in that capacity until 2022, while also ministering at St Christopher’s Cathedral and leading several parishes, most recently St Gregory’s Parish, Queanbeyan.
On 11 February 2025, Pope Francis appointed him Auxiliary Bishop of Sydney and Titular Bishop of Appiaria. He was consecrated on 2 May 2025 at St Mary’s Cathedral, Sydney.
Bishop Percy is widely respected for his theological insight, pastoral care, and dedication to fostering the mission of the Church across Australia.
