Duhig was born in Broadford, County Limerick but emigrated with his family to Australia as a young boy. He completed his education at St. Joseph's College, Gregory Terrace, Queensland. After that, he worked for the Cooperative Butchering Company. After undertaking his studies for the priesthood at the Irish College and Pontifical Urbaniana University, both in Rome, Duhig was ordained a priest in 1896 and his profile grew rapidly.
Episcopacy
On 10 December 1905, he became the youngest bishop in the Catholic Church when he was consecrated Bishop of Rockhampton. On 26 February 1912, he was transferred to Brisbane, where he became the coadjutor archbishop to the elderly Archbishop Robert Dunne. On 13 January 1917 he succeeded as Archbishop of Brisbane, a position he held for 48 years until his death in 1965. In the early years of Duhig's tenure, his archdiocese took on an extensive building program, including churches, hospitals and schools, erecting more than 400 buildings, earning him the nickname of "Duhig the Builder". These buildings are a prominent feature of the Brisbane landscape to this day. His most ambitious project, the Cathedral of the Holy Name in Fortitude Valley, was a casualty of the Great Depression which destroyed the value of the investments that were to finance the project. In addition to the construction of buildings, Duhig created over fifty new parishes and encouraged the establishment of twenty communities of religious men and women in an ecclesiastical province that had previously been dominated by the Irish Christian Brothers and the Sisters of Mercy.
Public life
Duhig played an active role in public life. However, unlike his contemporary, Archbishop Daniel Mannix of Melbourne, who seemed to thrive on public attention, controversy and inflaming public passions, Duhig favoured accommodation with the established order. This was reflected not only in his being awarded official honours, but also in the positive ecumenical legacy that he left to the Christian community in Brisbane and throughout the State of Queensland. In 1937 Duhig successfully proposed that the River Road should be renamed Coronation Drive, to celebrate the coronation of King George VI.
Honours
Duhig played a major role in the development of the University of Queensland, being a member of the university senate from 1916 until his death in 1965. He established St Leo's College, where an annual lecture is given in his honour. The university recognised Duhig's contribution by naming the Duhig Library after him and awarding him an honorary degree of Doctor of Laws. Duhig was appointed a Commander of the Order of St Michael and St George in 1954 in recognition of service as the Roman Catholic Archbishop of Brisbane, and made a Knight Commander of the order in 1959 in recognition of service as the Roman Catholic Archbishop of Queensland.
