The most significant factor in the Catholic Church becoming the largest Christian denomination in Australia since 1986 is increased immigration. Over recent decades, Australia has seen a rise in migration from predominantly Catholic countries such as Italy, Ireland, and the Philippines. This influx has directly contributed to the growth of the Catholic population, allowing the church to expand its demographics.

As immigrants settle, they often bring their religious beliefs and affiliations with them. This has led to a strengthening of Catholic communities within Australia, further bolstering the numbers within the denomination. Additionally, the community support and cultural ties from these immigrant groups foster a sense of belonging, encouraging ongoing participation in religious activities and church attendance, ultimately reinforcing the Catholic Church's position as the largest Christian denomination in Australia.
