For the past nine years, right-wing Dutch MP Geert Wilders has needed 24-hour police protection wherever he has travelled because the anti-Islam campaigner says he is never safe to walk the streets alone.
After flying into Perth on Wednesday, where he'd been forced to cancel a press conference and speaking engagement after a hotel scrubbed his booking, Mr Wilders said he had to have heavy security around him at all times.
He was dogged by people who wanted to kill him, which was hard on his family because they were not free, he said.
"I lost my own freedom. I haven't been able to walk alone on any street in the world for almost nine years," Mr Wilders told Fairfax Radio.
"But still, I know why I am doing it. I know that it needs to be done."
In 2002, during the Dutch election campaign, anti-Islam politician Pym Fortuyn was assassinated by a man who said he wanted to stop him scapegoating Muslims.
Mr Wilders, who says he is agnostic but ascribes to Judeo-Christian values, claims he does not have anything against Muslim people.
But he's against extreme Islam, he says, which has a "totalitarian ideology" like communism and fascism.
"I feel that we should stop it from coming to our free societies because Islam and freedom are incompatible," he said.
The controversial politician, who wants a ban on Islamic immigration, received a standing ovation on Tuesday in Melbourne, where up to 300 people dodged a large group of rowdy protesters to hear the first speech in his Australian tour.
Mr Wilders said it was "very sad" he could not find a venue willing to host him in WA after Premier Colin Barnett said he would not be allowed in any state government building.
"It's sad that I was not welcome in his state," Mr Wilders told Fairfax Radio.
He said in a democratic society like Australia, he should be able to express his opinions freely.
"Let's be happy we live in a democracy," he said.
"If people don't like my message then they should advocate their own message."
His next speaking engagement in Sydney on Friday is still planned to go ahead, event organisers Q Society of Australia told AAP.
