Nigel Farage has been on a tour of Australia and New Zealand for the past week delivering speeches.
But more than 200 demonstrators gathered in Melbourne on Friday to protest against the former Ukip leader.
In the shocking footage, the protesters appear to clash with police, with some chanting “Nazi scum”.
The demonstration was organised by the Coalition Against Racism and Fascism (CARF).
According to local police, multiple clashes erupted between anti-racism protesters and Farage supporters. Police were forced to intervene several times.
One protester, known as Victor, said: “You [Nigel Farage] are not welcome. Your message is filth and hate.
“It’s disgusting. And you are despicable.”
Five people were reportedly arrested at the event, two for unrelated matters, two for riotous behaviour and criminal damage, and one for assaulting police.
Police also had to form a human barrier around guests who were blocked from entering the event.
Protesters had mostly cleared from the area by 9:30pm local time.
The former Ukip leader is finishing his week-long tour of New Zealand and Australia which opened on September 2.
Earlier this week the former Ukip leader was forced to defend himself on Australian TV against protesters who accused him of violating the rights of Australian aboriginal people outside Perth Townhall.
The former Ukip leader was in Perth Town Hall on the first leg of his Australian tour on Saturday and was heckled by protesters outside the venue after his speech.
He said: “I’ve had to live nearly 25 years – particularly when I was absolutely at the frontline of national elections and the Brexit campaign – I’ve had to live with security around me the whole time.
“At times it was 24/7 security. They’ve even started attacking the houses of Conservative figures. At some point in time, surely, law and enforcement has got to say this is ridiculous. I did see a specimen last night of your Australian protesters outside the meeting in Perth Town Hall.
“And just to show you how rational and logical these people are, one of their big protest complaints was the way aboriginal rights had Nazi with.
“As if somehow I’m now guilty for what’s happened to the aborigines when I’ve got clearly nothing to do with it. It’s rent-a-mob, it’s anarchistic, it’s anti-democratic. People have a right to protest, but people do not have a right to stop other people speaking in a free society.”
