By "Pacific" I mean everything in the Pacific except the Solomons, which are grouped with Papua New Guinea in the Church organizational chart.
New Zealand and the Philippines are also not included in this region also called Oceania. Hawaii, though in the Pacific, is included in the U.S. dioceses.
By "diocese" is meant a number of Church entities. Every archdiocese is a diocese but, besides dioceses, there are also entities called Prefectures Apostolic and Missions.
So....which "diocese" in Oceania is the largest, in terms of population? Guam!
