Just after 10am on one of Sydney’s main Arabic radio stations yesterday, the strains of Arabic music gave way to a different sound — the Australian national anthem. A group of leaders from the Arabic-speaking community had gathered to launch a campaign to push back against extremist elements in the Muslim community. After hardline Islamic group Hizb ut-Tahrir on Sunday described the singing of the national anthem as “forced assimilation”, the group decided to sing the anthem both at the beginning and the end of their program. During the show, the group confronted groups like Hizb ut-Tahrir.
