The Australian Catholic Youth Festival (ACYF) is a national gathering of Catholic young people established by the Australian Catholic Bishops Conference (ACBC). It exists to provide young people with opportunities to deepen their relationship with Jesus, be empowered to be disciples in the world today and encounter and celebrate the vitality of the Church in Australia.
The Archdiocese of Sydney hosted the event from December 7th-9th 2017 on behalf of the ACBC. The Festival receives collaborative support from the agencies of the Archdiocese, and greater Sydney dioceses of Broken Bay, Parramatta and Wollongong.
The Festival launched the Year of Youth, celebrating ten years from when Australia hosted World Youth Day 2008.
