Lauren Southern has become the second controversial alt-right commentator to be slapped with a hefty police bill ahead of her controversial show in Melbourne.

Organisers of the Canadian’s speaking tour are reportedly being charged almost $68,000 for a large police presence at the event, which authorities fear could draw violent protesters.

While Victoria Police confirmed it had a right to charge any event organiser for the use of police resources, it refused to comment on the cost of the bill.

After initially being denied a short-term visa, Southern landed in Australia late last week for her national tour, wearing a shirt emblazoned with "It's okay to be white".
