The Federal Opposition Leader has rejected one of his own senator's claims of support for a planned visit to Australia by controversial Dutch MP Geert Wilders.

South Australian Liberal Senator Cory Bernardi wrote in a blog that he had invited Mr Wilders to visit Australia, and confirmed to the ABC he had offered to help arrange meetings and a schedule for the MP.

"I hope to be able within ... this year, or maybe the beginning of next year, to visit Australia," Mr Wilders said.

"I met one of your senators, Senator Cory Bernardi, not so long ago. He invited me to help him at least when I would visit Australia, and I will certainly do that as soon as I can."

The Dutch MP has caused outrage among Dutch Muslims after making comments comparing Islam to communism and fascism.

Tony Abbott says neither the Opposition, nor Senator Bernardi has any involvement with Mr Wilders' plans.

"Well that's not the position... he's not and the Coalition has nothing to do with the organisation of any trip," Mr Abbott said.

In a statement today, Senator Bernardi says Mr Wilders' remarks may have left some people with the impression that he was helping to organise the trip, but that is not the case.

"During my recent visit to Europe, I met with a number of parliamentarians including Mr Geert Wilders. During my meeting, Mr Wilders indicated that he hoped to visit Australia sometime and I said I would be happy to return the same courtesy he had shown me over lunch should that visit eventuate," he said.

"I wish to make it very clear that neither I nor the Coalition are organising a visit to Australia by Mr Wilders. Mr Wilders' travel arrangements are a matter for Mr Wilders."

Opposition treasury spokesman Joe Hockey has moved to further distance the Opposition from Mr Wilders.

"This gentleman seems like a very unpleasant character, and I think it's far better that we have nothing to do with him," he said.

Parliamentary secretary for immigration Kate Lundy says Mr Abbott must sanction Senator Bernardi.

"He said previously that if Senator Bernardi continued to express intolerant and extreme views that he would sanction Senator Bernardi and sack him from his front-bench position," Senator Lundy said.

"Where is he now, now that this issue has been raised again?"

Senator Lundy says Senator Bernardi should never have extended the invitation and should be sacked.

"I'm calling into question his judgment," she said.
