A spokesman for the far-right Australian Liberty Alliance has called for an "honest conversation" on Islam ahead of controversial Dutch MP Geert Wilders' speech in Perth.

Party spokesman Andrew Horwood told ABC radio that political correctness would lead to "the death of this country", and also campaigned for improved education and debt management ahead of the ALA launch on Tuesday, headlined by Mr Wilders.

"This political correctness where everyone has to think a particular way and we can't talk about issues will be the death of this country," Mr Horwood said.

"Islam in its current form doesn't fit with Australian values."

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

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

Mr Wilders posted on social media as he toured Perth on Monday, including a photograph with ALA representative Debbie Robinson enjoying a boat cruise on the Swan River.
