Why is this group not banned in Australia...

Is this group in Canada?

AN ULTRA-radical Muslim group banned in many countries will promote support for an Islamic superstate in a seminar in Australia this month.

Christian critics claim that the seminar, to be conducted by the group Hizb ut-Tahrir, will be a recruiting ground for extremists.

Hizb ut-Tahrir believes that the caliphate — a part of the world under Muslim rule that, at its peak, ran from Spain to Iran and beyond — is about to be re-established.

Hizb ut-Tahrir is banned in Britain, Germany, the Netherlands, Russia and most Muslim countries in the Middle East because of alleged links to terrorism, including the bombers behind the 2005 London attacks.

It is not banned in Australia but is controversial because it opposes democracy and Muslim integration, has tried to recruit young Muslims and ran a lecture last year titled "Israel is an illegal state that Muslims will never accept".
