The migration of Syro-Malabar faithful to the Greater Geelong region started in the 21st century. The first Syro-Malabar Qurbana in Geelong was celebrated by Fr. John Kariyathil VC on 23rd June 2010 at St Francis Xavier Church, Corio. Since then the small Syro-Malabar community in Geelong was helped by various priests Fr. John, Fr. Manoj, Fr. Pius and Fr. James. On the Pentecost Sunday of 2018 Fr. Abraham Nadukunnel, then Parish Priest of St Mary’s Syro-Malabar Parish Melbourne West, started regular Sunday Qurbana and Catechism classes.
