You think you would have this right if Australia was not raised on a Christian Heritage?
First census done in Australia was 1911 in which the question was compulsory to state what faith was followed (96%) The question in today's census is not compulsory (bit pointless IMO) but 1996 census has 70% stating they are Christian with not stated or no religion 25%

After 1975, the onset of civil war brought Lebanese Muslims here on grounds of humanitarian resettlement. At the same time, the policy of multiculturalism was initiated by the Whitlam Government and entrenched under Malcolm Fraser.
