Christchurch shooter's name, swastika sprayed onto Brisbane mosque

The Christchurch shooter's name, a swastika and a phrase from a Serbian anti-Muslim song have been spray-painted on the outer wall of a Brisbane mosque on Wednesday.

The Islamic Council of Queensland believes the perpetrator is not an irresponsible child, but a "highly radicalised" neo-Nazi and white supremacist.

Islamic Council of Queensland spokesman Ali Kadri said the graffiti was done between 2.30am and 4.30am on Wednesday at the Holland Park Mosque in Brisbane's south.

"The last person from the mosque who drove past and saw the wall was there at 2.30am and there was nothing there. The first members arrived for prayer at 4.30am and the graffiti was there," he said.

"It's about fear, but more importantly, it points to a highly radicalised person with the references to Brenton Tarrant [Christchurch shooter] and St Tarrant.

"The 'remove kebab' phrase was written on Brenton Tarrant's gun in Christchurch and comes from a Serbian anti-Islam song about the massacre of Muslims in Bosnia.

"It is related to the neo-Nazi and white supremacist movements. Whoever has done this is no child, they have been radicalised."

Detectives examined the scene on Wednesday and looked for DNA. They were expected to collect the mosque's security camera footage later in the day.

The mosque was in the process of removing the graffiti.

"Everyone in the community knows that Brenton Tarrant doesn’t define Australia," Mr Kadri said.

"This kind of graffiti at the mosque aims to terrorise the community, but it brings us together and we have had a lot of support from the wider community."

The vandalism was done on the 18th anniversary of the September 11 terrorist attacks in New York, when commercial planes were crashed into the World Trade Centre, the Pentagon and a field in Pennsylvania, killing an estimated 3000 people.

State Multicultural Affairs Minister Stirling Hinchliffe condemned the graffiti attack.

"Queensland is a diverse state and these types of vile actions in no way reflect who Queenslanders are," he said.

"We are a united and inclusive Queensland.

"We stand by our Islamic families and friends and the Queensland Police Service is doing everything to ensure that those responsible are caught and face justice."
