Controversial right-wing Dutch MP Geert Wilders will launch his Australian Liberty Alliance political party on Tuesday.

The party plans to unveil its Senate candidates for the next federal election at the event, which is being held at a top-secret location amid security concerns.

Mr Wilders visited Caversham Wildlife Park in Western Australia on Monday, with a spokeswoman saying he brought a big security contingent.

• Wilders to launch anti-Islam party
• Anti-Islam activist granted visa
• Muslim leaders: cancel anti-Islam activist’s visa

Four of the political party’s five directors are from the anti-Islam Q Society, which hosted Mr Wilders’ visit to Perth in 2013 when he was forced to call off a news conference and speaking engagement after the venue, a four-star hotel, cancelled his booking.

Some Muslim leaders have expressed concern that Mr Wilders’ visit will prompt more ill feeling against their community.

But the ALA party has welcomed the granting of his visa as a victory for free speech.
