. . . . "Islam in Australia is a minority religious affiliation. According to the 2011 census, 476,291 people, or 2.2% of the total Australian population, were Muslims. This made Islam the fourth largest religious grouping, after all forms of Christianity (61.1%), irreligion (22.9%), and Buddhism (2.5%). Demographers attribute Muslim community growth trends during the most recent census period to relatively high birth rates, and recent immigration patterns."@en . .
