Ms JULIE BISHOP (Curtin—Deputy Leader of the Opposition) (14:00): My question is to the Minister for Immigration and Citizenship. I remind the minister that, in 2005, British citizen and radical preacher Abdur Raheem Green was prevented from visiting Australia by the Howard government to speak at a conference at the Lakemba Mosque because he was on the Movement Alert List. Given that Hizb ut-Tahrir has advocated the military destruction of Israel and condoned the killing of Australian soldiers in Afghanistan, why is its UK leader, Taji Mustafa, not on the Movement Alert List?
