PRIME Minister Tony Abbott will "red card" members of groups like Hizb ut-Tahrir, denying them entry into Australia.
THE radical Islamic group will hold a lecture against United States-led combat in Syria in Sydney's Lakemba on Friday night.
Mr Abbott says the group is engaged in "hate preaching" and members should not be allowed to enter Australia to attend such events.
"By all means let Australians who want to say stupid things to say stupid things but there's no point importing troublemakers from overseas to stir people up," he told Macquarie Radio on Wednesday.
"I am sorry we haven't red-carded these hate preachers before but it will happen and it will happen quickly."
