Australia's immigration minister David Coleman cited the recent comments about Islam the right-wing provocateur made in the wake of the attacks on Christchurch, where the commentator said in a Facebook post that the establishment "mollycoddles extremist leftism and barbaric, alien religious cultures".
The minister's revocation comes just a week after he approved Yiannopoulos' visa to enter Australia, despite concerns Yiannopoulos wouldn't pass the country's "character test".
Coleman didn't specifically state which of Yiannopoulos' comments he was referring to.More news: Netflix confirms Madeleine McCann documentary date
The government had agreed to the visa after conservative MPs had put pressure on Mr Coleman to override the Department of Home Affairs' advice to ban Mr Yiannopoulos.
Coleman added that the attack, which left at least 49 Muslim worshippers dead and dozens injured, was "pure evil". "So Australia banned me again". The former Breitbart News editor, who famously backs the Trump administration, has been banned from platforms like Paypal, Twitter, and Patreon because of his vitriol.
"Surely the Liberal government is not going to issue a visa to someone so he can conduct a tour to promote hatred against Muslims", said Australian Labor Party representative Tony Burke. There was already enough evidence to ban him which is why the department had already recommended he be banned.More news: Jurgen Klopp says Liverpool don't need another summer spending spree
The ultra-right public speaker, a British national, who lives in the USA, was scheduled to tour Australia later this year to speak at a series of events.
The speaking tour had previously been given the green light despite Mr Yiannopoulos owing Victoria Police $50,000 to cover policing at a Melbourne event in December, 2017, during which up to 500 left-wing protesters clashed with about 50 right-wing activists.More news: World Rugby offers nations £5 billion for new Nations Championship
