Milo Yiannopoulos and his promoters won't pay the $50,000 they will be asked to cough up to cover the heavy police presence at his Melbourne show.

Police Minister Lisa Neville said the event's organisers would be sent the bill after protesters violently clashed outside the Kensington venue on Monday night.

Yiannopoulos' Australian tour promoter Damien Costas defiantly argued 'his people' had nothing to do with the violence and said he will refuse to cover the cost.

'This is political grandstanding. It's actually absolute nonsense,' he told Daily Mail Australia on Thursday.

'My answer to politicians that like to get political mileage out of something - in this case the Police Minister - my answer to her is quite simple: "Sue me".

'And I will call, during the trial, every single one of the 3,000 people that were there who can demonstrate it wasn't us that caused the problem.

'If it was our people that did it, I'd probably be liable, but our people didn't do it. The people that did it weren't welcome there.'

Mr Costas argued the minister could not justify the bill and said he had extensive negotiations with Victoria Police ahead of the event.

'In good faith we offered to pay [for police presence] - we asked if there was going to be a cost and the answer was no.

'For her to get involved after the event demonstrates very clearly where politics is at in this country.'

Ms Neville said on Wednesday she didn't know if Yiannopoulos' promoters would agree to pay the bill, but said it was standard practice for these kinds of events.

'There was a lot of kerfuffle out front,' Yiannopoulos said responding to the violent scenes

'I'm not sure whether they have [agreed to pay it] but they will certainly be getting a bill for it,' she told 3AW.

Hundreds of police were sent in to control up to 500 left-wing and up to 50 right-wing activists outside the event.

Five officers were pelted with bottles and rocks and two protesters, one from each side, were arrested during the violent scenes.

Yiannopoulos, who arrived in Australia last week for his seven-show tour, slammed the 'violent' left-wing protesters for causing the trouble that required heavy police presence.

'There was a lot of kerfuffle out front,' he told Alan Jones on 2GB Radio on Tuesday.

'It was not as the newspapers reported ''a clash between the far left and far right'' it was the left, showing up, being violent to stop freedom of speech.

'The left really showed us who they are. They attack the police, they attacked other people, they attacked journalists - they showed us they are petulant babies.'

Similar scenes unfolded on Tuesday night at Yiannopoulos' first Sydney show at the Le Montage in Lilyfield.

Seven protesters were arrested outside the venue, which was heavily guarded by mounted police, officers on bicycles, the riot squad and marine police.

Fans of the right-wing commentator were heckled by more than 100 protesters as they entered the venue, with police having to stand between the two groups.

Four people were arrested for breaching the peace, one for assaulting a police officer, one for affray and one for not complying with direction.

Banners and placards saying 'f*** off Nazi scum' and 'kill yourself like Adolf Hitler' greeted Yiannopoulos as he arrived to denounce Islam, feminism and cultural Marxism.

Police on horseback were called 'animals' and 'racist pigs' as they kept more than 70 youthful demonstrators to a patch of grass by the shores of the Parramatta River.

Protesters held signs including a large banner that said: 'First they came for the Muslims and we said, 'Not this time you f***er'.'

There were no arrests at Yiannopoulos' second Sydney show at the same venue on Wednesday night.

Yiannopoulos' speeches on university campuses in the US have previously sparked violent protests.

He was banned from Twitter last year after being blamed for a barrage of racist abuse directed by his fans toward Ghostbusters star Leslie Jones.

He has previously likened feminism to cancer, Islam to AIDS and has spoken out against gay rights and the Black Lives Matter movement - despite being openly homosexual and married to an African American man.

Yiannopoulos lost a book deal after a video emerged in February in which he said some relationships between older men and teenage boys could be beneficial.
