SYDNEY (Reuters) - Australian Prime Minister Tony Abbott said on Wednesday that he was ordering a crackdown to prevent radical Islamist preachers entering the country, amidst rising tension with the Muslim community following a series of security-related raids.
Abbott, who recently warned that the balance between freedom and security "may have to shift" to protect against radicalized Muslims seeking to carry out attacks, said hate preachers would now be "red-carded" during the visa process.
The tougher new system, which he said would not require new legislation, comes on the heels of a speech in Sydney last week by Hizb ut-Tahrir, an international group that says its goal is to establish a pan-national Muslim state.
Conservative commentators have seized on the speech to urge greater restrictions on radical preachers.
"What we want to do is to ensure that known preachers of hate do not come to this country to peddle their divisive extremist message," Abbott told reporters in Sydney.
"What I'm doing is declaring that we will henceforth have a new system in place which will ensure that preachers of hate can't come to Australia to peddle their extreme, divisive and alien ideologies."
Australia is on high alert for attacks by radicalized Muslims or by home-grown militants returning from fighting in the Middle East, having raised its threat level to high and undertaken a series of high-profile raids in major cities.
Officials believe up to 160 Australians have been either involved in fighting in the Middle East or actively supporting groups fighting there. At least 20 are believed to have returned to Australia and have been said to pose a security risk.
Prominent Australian Muslims say their community is being unfairly targeted by law enforcement and threatened by right-wing groups, and there are concerns that policies aimed at combating radical Islamists could create a backlash.
