A controversial Muslim sheikh who likened Christians to terrorists and described the Australian flag as a 'bloody symbol' of colonial oppression has been pulled off the speaking list for a mosque open day in Queensland.

Sheikh Zainadine Johnson, a redhead who is also a surfer, was meant to be a keynote speaker for the Garden City Mosque in Toowoomba on Sunday.

However the Anglo-Saxon Muslim convert, who used to play in a Brisbane rock band Grinder, will no longer be appearing as a speaker in the Bible belt city, following a backlash.

Event organiser Imam Abdul Kader said Sheikh Johnson cancelled his own appearance.

'He can't make it this year,' he told Daily Mail Australia on Sunday.

'We had a chat and he felt like, "No".'

Sheikh Johnson was recently dismissed as a Sunshine Coast imam and has made a serious of controversial statements.

In February, he posted a YouTube clip which blamed Christians for killing indigenous people and claimed the Australian flag was 'a bloody symbol of colonial history'.

Sheikh Zainadine Johnson likened Australia's early colonial Christian settlers to terrorists

'The truth is that Australia, hundreds of thousands of indigenous people were exterminated by Christians Australians, by white Christian Australians whether they were civilians or whether they were government workers,' he said.

'And they often used the most vile tactics that one would expect from a certain terror group today that is terrifying the people around the world.'

He compared the British unfavourably with Muslim Indonesians when it came to relations with Australia's indigenous tribes in Australia's far north, describing 18th century European colonialists as thieves.

The Muslim convert who also surfs has caused a ripple effect with his comments on Christians

'They invaded in the name of Christianity and expansion of the king or queen's empires but more significantly, the belief in European white supremacy,' he said.

'The history of indigenous people here in Australia, in fact anywhere in the world over the past 400 years, is an untold story of slavery and genocide.'

The sheikh was meant to have appeared alongside Toowoomba Mayor Paul Antonio.

Daily Mail Australia attempted to contact Sheikh Johnson.

However, the Sunni sheikh had told The Courier-Mail his bearded appearance as a 'salafist', an ultraconservative form of Islam from Saudi Arabia, may have polarised the community.
