Regional groups of bishops conferences around the world collaborate on key areas of mutual importance for the life of the faithful in their own countries or areas.

The Federation of Catholic Bishops Conferences of Oceania is the regional grouping that comprises the Australian Catholic Bishops Conference, the New Zealand Catholic Bishops Conference, the Catholic Bishops Conference of Papua New Guinea and Solomon Islands and the Episcopal Conference of the Pacific (CEPAC) – which includes Cook Islands, Fiji, French Polynesia, Guam, Kiribati, Marshall Islands, Micronesia, New Caledonia, Northern Mariana Islands, Samoa, Tonga, Tuvalu, Vanuatu and Wallis and Futuna.

The bishops of those four conferences gather every four years for a continental gathering. The next such gathering is scheduled for 5 to 10 February 2023 in Fiji.
