This is the moment right-wing provocateur Milo Yiannopoulos tells an Islamic woman that he believes Muslims should be 'expelled' from Australia and 'sent back' to the Middle East.

Emma Eros, who was born in Australia to Lebanese-Muslim parents, told the British-born media personality that Muslims like herself were standing up to Islamist fundamentalists.

Ms Eros, who supports banning the burqa, asked the 33-year-old right-wing author for a solution to Islamic extremism in the West during an interview on Wednesday.

'Expel Islam from the West,' he said on the sidelines of a media conference in Sydney.

'Anyone who describes themselves as a Muslim, send them back to the Middle East,' he added.

Ms Eros, who runs her own construction plumbing business, asked Yiannopoulos if he meant she should be deported.

'If you describe yourself as a Muslim. If you believe in the precepts of Islam. All the things Islam seems to produce in those countries, I think you should go,' he said.

When Ms Eros suggested Yiannopoulos needed to understand 'what Islam actually means', he claimed the later verses of the Koran had superseded the peaceful, earlier parts of the holy book.

'I seem to understand more about the Koran than you do,' he said.

Conservative Jewish activist Avi Yemini, a former Israeli soldier, held the microphone during the clash and posted the footage to his Facebook page.

Earlier, Yiannopoulos had demanded to know if Ms Eros, a married mother-of-two who doesn't attend a mosque, prayed five times a day.

The 38-year-old businesswoman said she wasn't 'the best' when it came to being devout and blamed bad interpretations of Islam for terrorism and extremism.

'We can slap each other back and forth,' Ms Eros said.

Yiannopoulos quipped: 'I'm not going to slap you. I don't use violence.'

The former technology editor of the right-wing American Breitbart media website was due to front a forum in Sydney on Thursday night.

But that was postponed until Tuesday next week following threats of protests.

The Greens have also tried to have him banned from speaking next week at Parliament House as a guest of Liberal Democrats senator David Leyonjhelm.
