Extra security measures are expected to be in place when controversial right-wing commentator Milo Yiannopolous visits Parliament House in Canberra.
A fight broke out between his supporters and protesters at Yiannopolous's event in Melbourne on Monday and police were forced to use pepper spray.
The self-described "one-man wrecking crew" and "internet supervillian" will visit Parliament House on Tuesday at the invitation of Liberal Democrat Senator David Leyonhjelm.
The Australian Greens had unsuccessfully attempted to have him banned from the building.
Senator Leyonhjelm flagged security arrangements are likely to be beefed up for the visit.
"I wouldn't call myself a disciple of him by any means," Senator Leyonhjelm told AAP, adding he didn't agree with all his controversial views.
He expects Yiannopolous to embark on an "outrage campaign" to stir up the politically correct.
"I'm expecting to be amused more than anything," Senator Leyonhjelm said.
Yiannopolous defended his right to free speech, saying his aim is to entertain, challenge and educate.
"I may not be to your taste and that's OK, don't send your kids to my shows, but I am to plenty of peoples' tastes," he told Sky News.
"What they leave with... isn't 'he's so rude and tells fat jokes'... what they leave with is 'I never even considered that'."
Yiannopolous says he "blows open the fire doors" in a way that is crass but gains attention.
Yiannopolous's speeches on university campuses in the US have sparked violent protests, and he was banned from Twitter last year amid a barrage of racist abuse directed at Ghostbusters star Leslie Jones.
The British-born, US-based commentator lost a book deal after a video emerged in February in which he appeared to suggest it was OK for older men to sleep with young teenage boys.
