A man wearing an Islamic prayer cap, or “Kufi”, looks at Islamic books on display at a bookshop located in the western Sydney suburb of Lakemba October 3, 2014. Last month, the national security agency raised its four-tier threat level to “high” for the first time and about 900 police launched raids on homes in Sydney’s predominantly Muslim western suburbs and in Brisbane. Only about half a million people out of Australia’s 23.5 million are Muslims, making them a tiny fraction in a country where the final vestiges of the “White Australia” policy were only abolished in 1973, allowing large scale non-European migration. At least half of Australia’s Muslims live in Sydney’s western suburbs, which were transformed in the mid-1970s from white working-class enclaves into majority-Muslim outposts by a surge of immigration from Lebanon.
