An internationally prominent Islam critic Ayaan Hirsi Ali is urging Australians to boycott halal-certified food so they're not funding Muslim schools, mosques and Islamist propaganda.

The producers of popular supermarket items like Vegemite and Cadbury chocolates pay halal fees to third-party certifiers to declare the products are fit for Muslims.

Ms Hirsi Ali, a Somali-born author now living with bodyguards in the United States, says halal-certification is an example of a campaign to Islamise the West, as part of a political strategy called 'dawa'.

Islam critic Ayaan Hirsi Ali is urging Australians to boycott halal-certified food on the shelves

'I would have a boycott - all halal food,' she told Daily Mail Australia from an undisclosed location in the U.S..

'It's not fair to Muslims and non-Muslims to be the victims of a marketing scheme that's mainly used to support an ideology ... that violates the rights of humans.'

The writer, who wants Islamic schools in Australia shut down, said halal-certifed food and meat slaughtered in accordance with Muslim tradition needed to be more clearly labelled.

'If I think I'm funding Islamic dawa, I will not buy that particular product so it has to be made very clear that that's exactly what the money's being used for,' she said of the scheme which ensures products contain no pork or alcohol derivatives.

The Australian Federation of Islamic Councils funds the Malek Fahd Islamic School in Sydney's south-west.

The group also charges a halal certification fee to brands such as Vegemite.

Ms Hirsi Ali, a former federal lawmaker in The Netherlands, is also backing the Australian government's proposal to ask migrants about female genital mutilation and child brides.

The 47-year-old ex-Muslim was circumcised in Somalia when she was five and campaigns against the practice through her AHA Foundation.

She blasted left-wing critics of the Turnbull government's plan who say it's targeting Muslims.

'Anybody who wants to consider coming to Australia ... will think twice about engaging in these practices so in that sense the left is absolutely wrong,' she said.

The former refugee, who was granted asylum in The Netherlands in 1992 to escape an arranged marriage, said multiculturalism had failed and urged Australia to be restrained in accepting Muslim asylum seekers.

'The left is also wrong in failing to acknowledge that the ideology of multiculturalism has failed and that values are not equal,' she said.

'Some values are superior to others and I believe that Australian national values and laws are superior to the Sharia system.

'It's high time now that Australia and other Western countries make it explicit to Muslims and non-Muslims what these laws and what these values are.'

Hizb ut-Tahrir leader Uthman Badar confirmed ex-Muslims deserved to be put to death

She also called on the Australian government to reconsider its decision not to ban Islamist extremist group Hizb ut-Tahrir, which is illegal in The Netherlands, Germany and a range of Muslim-majority nations including Indonesia, Pakistan and Bangladesh.

While the group campaigning for a global Islamic caliphate based on Sharia law hasn't committed violent acts in Australia, it has a constitution calling for ex-Muslims to be killed.

'Some people who have been influenced by Hizb ut-Tahrir have taken up arms, they've engaged in terrorism so it's very clear that there's a connection between the ideology that Hizb ut-Tahrir promotes and the violence that is generates,' she said.

'It's the swamp terrorists swim and plan and plot and propagate and get financial help. I would join the other countries in banning Hizb ut-Tahrir.'

The atheist convert, who questioned her Muslim faith after the September 2001 terrorist attacks in the United States, disputed the use of the term 'Islamophobia' to describe violence against Muslims.

Ayaan Hirsi Ali said attacks on Muslims should be described as prejudice not Islamophobia

'I would not call it Islamophobia, I would call it a very clear act of prejudice and that sort of thing has to be dealt with in exactly the same way that we deal with other terrorists,' she said.

'It should be condemned and it should be stopped. But we must not allow ourselves to be morally blackmailed.'

Ms Hirsi Ali, who spent her childhood in Somalia, Kenya and Saudi Arabia, said the harassment of Muslim women for wearing the hijab should be regarded as an act of prejudice not an example of Islamophobia.

'It's got to do with prejudice, prejudice against people who look different and who are different.

'It hasn't disappeared and of course Islam is in the news a lot in many bad ways.

'If you have acts of Antisemitism, racist acts, acts against Muslims, purely because of who they are, these should all be treated in the same way.'

The former Dutch politician said the Australian Labor Party (federal leader Bill Shorten pictured) was 'becoming partially Islamised'

The former conservative politician in The Netherlands, who had earlier worked as a researcher with a think tank linked to the Dutch Labour Party, criticised a planned Australian Labor Party motion to give unconditional recognition to Palestine.

She said the major party, formed in 1891, was 'becoming partially Islamised' as it courted Muslim support in western Sydney.

'It's beginning to show some of the signs of depending on the Muslim vote,' she said.

'If you look at the history of the Islamisation of politics, the Islamists have put all their bets on left-wing parties, centre-left parties.

'So labour parties, social democratic parties and socialist parties and for some reason these parties seem to be the most open to this type of infiltration.'
