Pauline Hanson has compared her version of monoculture to the Socceroos, while Angus Taylor's Liberal leadership has come under fire after failing to clearly support multiculturalism.

The One Nation leader copped backlash last week when she said that Australia could not 'be a multicultural society' but instead a monocultural one in her first National Press Club address.

However, Hanson clarified that not much would change under her policy in the Senate on Wednesday, saying the Socceroos were a great example of what she envisioned.  

'In the past week the far left have, naturally, taken my comments into the realm of utter fantasy,' she said. 

'I was going to ban foreign food and the Socceroos wouldn't have beaten Turkey under my policy. What rubbish. Predictable and pathetic.

'The Socceroos, in fact, represent my vision of a monocultural Australia. People from different background and cultures and nations all wearing the green and gold and representing one nation under one flag and succeeding under the same set of rules.'

She also pointed to Japan as an example, where foreign residents follow the same customs and learn the same language as the locals.

When asked to respond to her comments, Angus Taylor received criticism on Tuesday when he couldn't clearly outline what the Liberal Party's stance on multiculturalism was, even though he was asked five times by reporters.

'You explain to me what you mean by that,' the Opposition Leader said at the time.

'There is all these vague words running around. I'll tell you what, the one thing I want all of us to share is those core Australian values.'

Among opponents calling out Mr Taylor's indecision was Housing Minister Clare O'Neil who called out his party on ABC Radio National.

'They are inert, they are cowardly, they are frozen,' she said.

'When are [the Liberal Party] going to stand up and fight against the absolutely outrageous nonsense that One Nation are spreading right around this country?'

It seems they have been joined by those within Taylor's own party, with The Australian reporting 'several' Liberal MPs have said his leadership has an expiration date unless he swiftly and firmly gets some 'cut through' on One Nation and Labor.

Taylor has since told 2GB he was against Ms Hanson's views and that he supported 'a version of multiculturalism'.

'We should have a common set of values we all agree on,' he said. 

'We need every Australian to believe in our system of law, to believe in our basic freedoms, to believe in our parliamentary democracy, and people have been coming to this country, in recent times, who do not believe in those things, and that should not happen. 

'Making sure that people who come to this country contribute to this country and commit to it, that's not a monoculture, but it is requiring that people adopt Australian values.

'If someone comes here with ISIS culture, Islamic State culture, no, no. That's exactly why we ended up with what we had at Bondi at the end of last year.'

Some of Taylor's colleagues have come out in his defence, including deputy leader Jane Hume, who told the ABC the country was already multicultural. 

'This is a ridiculous argument,' she said. 

'I can't believe that we've managed to get ourselves into this. 

'I reject the politics of identity of the left on multiculturalism but, my goodness, I also reject the policy of cultural fear on the right.'

Liberal frontbencher Anne Ruston shared similar sentiments. 

'We want a future for Australia that is built on respecting our values and our way of life … and the future of Australia is one that is based on multiculturalism,' she said.

'I am not going to go into semantics on who said what word, but I do know that we in the Coalition believe in an Australia where everyone respects our laws.

'They share our values, and contribute to the fabric of our country, and that is multiculturalism and that is what we believe in.'
