Labor has accused Federal Government MP George Christensen of stirring up community division by supporting an anti-Islamic group that promotes "racist" behaviour.

The member for the Queensland seat of Dawson has confirmed he will speak at the Reclaim Australian rally in Mackay this weekend.

"I want to support people who seek to defend our Australian way of life, our culture and our freedoms from the threat of radical Islam," he said in a post on Facebook.

But Labor's immigration spokesman Richard Marles said the Government should be focused on social inclusion, not "whipping up division".

"It is extraordinary that a member of Tony Abbott's Government will attend and address an anti-Islam, Reclaim Australia event," he said.

"Reclaim Australia events are synonymous with racist behaviour."

Mr Christensen said he would not be intimidated by attempts to stop him taking part.

"Hell will freeze over before I give in to such intimidation," he said.

"However, it's plain to see who wants to shut down free speech and the right to peaceful assembly and protest in this country."

Mr Christensen said he made the decision after reviewing the movement's principles, which call for "equality of law, equality of genders and freedom of speech, as well as supporting Australia's right to exile or deport traitors".

The Facebook page for the rally advertises the event as "completely halal free".

Reclaim Australia describes itself as representing patriotic Australians who "need to stand together to stop halal tax, sharia law and Islamisation".

The page says racist banners and anti-social behaviour will not be welcome at the Mackay rally.

It encourages people to support another group, "Australians Against Islam", in Mackay, who promote the "rebuke of Islam and its tyranny".

Fellow Queensland MP Ewen Jones said he would never speak at a Reclaim Australia rally and his position is pro-immigration.

"George is a very good friend of mine but we are very, very different people," Mr Jones said.

"I would never speak at a Reclaim Australia rally. I believe that whatever people bring to this country, they add to it."
