(Ahlul Bayt News Agency) - The Baillieu Government has also warned that Mr Wilders could fall foul of the state's hate speech laws if he incites tensions.
Mr Wilders had been due to visit Australia last year but had to postpone the trip following delays in processing his visa.
He opposes the "Islamisation" of the Netherlands and has called for the banning of the Koran, which he equates with Adolf Hitler's autobiography Mein Kampf.
Mr Wilders was invited to Australia by a nationalist group called the Q Society.
A meeting is planned for Melbourne on February 19, and there are appearance dates in Sydney and Perth.
Islamic Friendship Association president Keysar Trad said he had been approached by Leftist groups about protests against the Right-wing politician.
Q Society spokesman Andrew Horwood said details of meetings would be released with only 48 hours' notice, for security reasons.
"We feel strongly that as a democracy we can't not talk about things because of the threat of violence," he said.
Mr Horwood said Islam was unlike any other religion, and his organisation was concerned that Australia, like Europe, was changing as Muslim numbers grew.
Victorian Multicultural Affairs and Citizenship Minister Nick Kotsiras said Mr Wilders had the right to free speech, subject to the state's racial and religious vilification laws.
