It appears controversial Dutch MP Geert Wilders' visa to Australia has stalled, meaning he may be unable to launch a new Australian anti-Islam party later this month.

The right-wing Dutch politician has applied for a visa to go to Perth to launch the Australian Liberty Alliance (ALA) - a party inspired by his own.

Party's president says delay in Dutch MP's visa unacceptable Wilders is a staunch opponent of Islam with controversial views

But the visa is still yet to be granted and ALA president Debbie Robinson is suspicious of the delay.

"I believe that they're stonewalling the visa... I believe that they are playing political games and in a way it is an assault on our freedom of speech," she said.

"An advanced party from the Dutch police was here last month and we were given assurances in August that his visa would be forthcoming but I learned last week that it still has not been granted and I think it's unacceptable."

It is not the first time Mr Wilders has faced visa issues in Australia.

In 2012, he was invited to give a series of speeches by the anti-Islam group the Q Society, which Ms Robinson is the president of, but that application was stalled and he ultimately had to cancel the speaking tour.

After eventually securing a visa, he visited Australia in February 2013, where the idea for the Australian Liberty Alliance was formed.

Ms Robinson said she was disappointed he was facing visa issues again.

"I'm surprised that with the change of government, we now have a Liberal Government, that it appears that in fact nothing has changed," she said.

"It's all about appeasement and political correctness."

Mr Wilders is a staunch opponent of Islam and has sparked controversy by comparing the Koran to Hitler's Mein Kampf, describing Islam as a retarded culture and calling the Prophet Mohammed a paedophile and a terrorist.

Ms Robinson said she did not think his views were dangerous despite recent cases of radicalisation and the growing threat of homegrown terror.

"I think it's more dangerous to invite for example and fast-track visas for people like Tareq Al-Suwaidan, who was the leader of the Kuwaiti Muslim Brotherhood, Taji Mustafa who is a British spokesperson for Hizb ut-Tahrir," she said.

"These guys are allowed access to our country to deliver their message and an elected member of a democracy with no criminal record who does not incite violence is not allowed to speak. I think that's outrageous."

The 2012 delay was due to the Dutch politician being on the Movement Alert List, a database of people of concern to Australia.

That meant the Department of Immigration had to do more thorough checks before granting a visa.

In a statement, the Immigration Department said it did not comment on individual cases and processing times may vary.
