Police have been called after an ugly confrontation broke out at a Brisbane mosque between activists describing themselves as Christian documentary makers and Islamic leaders.

The group of at least four activists, who were involved in a similar incident at the Kuraby mosque yesterday, confronted worshippers at a Darra mosque in Brisbane's south-west just before midday on Thursday.

When they were denied access, a heated argument broke out between self-declared activist Logan Robertson and Ali Kadri from the Islamic Council of Queensland.

Mr Kadri asked: "I'm trying to talk to you in a nice manner, why are you responding in such an aggressive manner?"

Mr Robertson replied: "Because I hate the religion of Islam. I don't hate Muslims, I hate the religion."

Police intervened and forced the group to leave the property.

Authorities said a group of up to six men went to a mosque at Kuraby yesterday and harassed some of the worshippers in the lead-up to 1:00pm prayers.

Nobody was injured in the incident and no charges were laid.

Mr Kadri said a teenage boy was verbally abused during yesterday's incident and was called a terrorist.

"Why did you abuse a 15-year-old Muslim kid then?" Mr Kadri asked.

Mr Robertson replied: "We didn't abuse him."

Mr Robertson, who said he represented the Pillar Baptist Church at Ipswich, also claimed he was part of a group making a film on Islam.

"We're making a documentary about your false religion that's what we are trying to do," Mr Robertson said.

"You are not a patriot, you are a hateful hatemonger — that's what you are, my friend," Mr Kadri said.

"Despite you being a hatemonger, I don't hate you."

The Queensland Baptists said Mr Robertson and his church were not registered or affiliated with their association.

"Queensland Baptists do not support or condone his behaviour toward other faiths as reported in the media."

'What's next, will they come into our houses?'

Mr Kadri said the men were "extremists" and likened them to "white ISIS [Islamic State]".

"Unfortunately if we don't rein these kind of people in this country, then these people in absence of law will not only just harm minorities like us.

"They are going to harm their own people who don't agree with them ... so to me, he is an extremist," Mr Kadri said.

"I think these kinds of people are white ISIS."

Mr Kadri said security would be increased at mosques around the state and most of them would now be locked at night.

"I don't think there is any justification for these kind of things ... our mosques are a peaceful congregation," he said.

"Do we have to wait for somebody to get killed before we realise? This kind of hatred has to be addressed and condemned.

"Before, it was individuals on the corner street ... now they've actually come inside a mosque — what's next, will they come into our houses?"

Not long after the confrontation inside the Darra mosque, police stopped the men on the side of a road and confiscated their camera equipment.

"We'll continue making our documentary," Mr Robertson said.

He told media he was not racist.

"We've got Asians in our church, there's Pacific Islanders in our church — there's all types of races in our church. We're not racist at all, it's about a religion," he said.

Who is Logan Robertson?

A self-proclaimed pastor of the Pillar Baptist Church, which opened at Goodna, west of Brisbane, within the past 12 months.

It is not affiliated with the mainstream Baptist denomination.

The church declares it is anti-abortion, anti-gay and anti-Islam.

Mr Robertson posts sermons on social media and also released a "documentary" critical of the Mormon faith.

On the church's website, Mr Robertson describes his church as a "New Testament Independent Fundamental Baptist Church".

"Our Church is a friendly group of believers who have a strong desire for truthful biblical preaching, that isn't watered down or compromised," the website says.

In New Zealand, Mr Robertson sparked controversy by saying people in gay marriages should be shot, and that New Zealand Prime Minister Jacinda Ardern should "get in the kitchen where women belong".

He was rebuked by Baptist Churches of New Zealand in 2014, who said he had never been affiliated with their denomination.

"The NZ Baptist churches have been demeaned by his vitriol, leaving many of our Baptist church members and pastors wrongly implicated by Robertson's actions," the church said.

New Zealand police reportedly launched an investigation into Mr Robertson but dropped the case on the basis there was no evidence to suggest he had committed any crimes.
