Peter Dutton has vowed to 'do whatever it takes' to kick out migrants who spread hatred in Australia if he is elected Prime Minister.

The opposition leader floated the idea of a constitutional referendum in order to achieve his goals while speaking at The Advertiser's Future SA forum on Friday.

His comments were sparked by a vile video uploaded by Israeli influencer Max Veifer which caught two Bankstown nurses stating they would kill patients from his country.

One of the nurses in question, Ahmed 'Rashid' Nadir, had been granted Australian citizenship four years ago and Mr Dutton previously said he wants to rescind that honour. 

Mr Dutton said any migrants either with or without a citizenship should be expelled if they were to engage in anti-Semitic attacks or if they were to 'hate our country'.

Both Mr Nadir and the other nurse, Sarah Abu Lebdeh, have apologised for their outburst which involved them making throat-slashing gestures towards Mr Veifer.

The pair have insisted they were joking and taken out of context in the confronting video. 

Mr Dutton highlighted the fact that despite Mr Nadir's actions it is currently impossible to expel him after he gained Australian citizenship after fleeing from Afghanistan.

Mr Dutton is now intent on fixing the constitution so as to not rule out any punishment for those who 'have broken their allegiance with our country'.

'If somebody commits a terrorist act against our country, they have broken their allegiance with our country, and we have laws which allow the stripping of citizenship from people who commit terrorist attacks, but the High Court has limited the application,' he said at the forum reported new.com.au.

'There's provision under the Migration Act which allows for a revision of a decision being made to grant citizenship in narrow circumstances where people have made a false declaration.

'I look at what's happened to the Jewish community. I was at Central Synagogue in Sydney yesterday. It is, I think, the most shocking thing I've seen in my lifetime.'

He recalled the guards, bombproof shelters and abuse that Jewish individuals had gone through over the past several months and years in his speech as well.  

'This has no place in our country whatsoever,' he added. 

Mr Dutton said he does not care if the hatred is cast upon Jewish people, Indians, Greeks, Asians or any particular religion but just that he wants it all to stop.

He reassured the crowd that he still believes Australia 'is the best country in the world' but that to maintain that high standard 'we have to bring the best people into our country'.

However Mr Dutton insisted that if any of those who want to enter the country were to ever turn their back on its values then there must be consequences. 

Chief among them being that those who betray what he sees as the right way for migrants to integrate should be deported. 

Although the opposition leader did concede that he does 'think the Constitution is a barrier, yes'.

In light of this Mr Dutton swore to attempt to 'amend' the document should he be granted the power to do so after the upcoming federal election. 

The election must be held on or before May 17.
