Far-right provocateur Lauren Southern has reportedly been sent a $68,000 bill from Victoria Police for their resources to be used at her show in Melbourne on Friday.

The Canadian commentator is expected to share her controversial views on multiculturalism, Islam and feminism during the event, at an undisclosed location, on Friday.

An email from Victoria Police quotes the total cost as $230,000 but said police would only charge her $67,842.50, News Corp Australia reported.

"As per the Victoria Police (fees and charges) Regulations 2014, Victoria Police has the right to charge any event organiser for the use of police resources," a spokesman told AAP.

The Campaign Against Racism and Fascism has organised a protest in Melbourne to "show fascistic ideas will always lose in Melbourne" against Ms Southern's show.
