A police officer was injured and two protesters arrested in a violent clash outside controversial alt-right commentator Milo Yiannopoulos' Melbourne event.
The former Breitbart News tech editor called the protesters "petulant babies" for coming out against him.
"There was a lot of kerfuffle out front, 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," Mr Yiannopoulos told 2GB radio on Tuesday.
"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."
Anti-fascist and hardline right-wing groups clashed outside the Melbourne Pavilion in inner-city Kensington on Monday night, with protesters brawling in the streets and wielding crude weapons.
Scores of protesters from left-aligned Campaign Against Racism and Fascism and two right-wing groups, Reclaim Australia and the True Blue Crew, rallied with a heavy police presence attempting to maintain order.
Convicted stalker and racial vilifier Neil Erikson and fellow right wing activist Avi Yemeni were among the crowd.
Dozens of officers worked to keep the groups separated, but still had to use pepper spray on the crowd.
One officer was hurt after being hit by a rock and two protesters were arrested for discharging a missile.
Victoria Police will talk about the incident at 11am on Tuesday.
Australian commentator Andrew Bolt, who was MC at the Melbourne event, described the protests as a scandal.
The polarising British-born commentator is touring the country and is due to speak in Canberra, Sydney and the Gold Coast.
The 33-year-old resigned from conservative website Breitbart News earlier this year after he suggested it was acceptable for older men to sleep with teenage boys.
