Supporter Dan Evans, who spoke at the rally, told the crowd he would not “submit to inferior cultures”.

“I will not submit to inferior cultures… to communist, left-wing, Marxist ideologies,” Mr Evans said.

“Australia is a monoculture. One culture, an Australian culture- the superior culture.”

A large police presence is also at the protest, with reports there are more officers than Reclaim Australia supporters.

About 400 people registered via Facebook to attend the rally.

Organisers last night took to Facebook to state that face coverings would be banned at the rally.

Police have warned CBD drivers, residents and visitors that there may be traffic disruptions, with plans to close roadways near the rally if necessary.

Sections of Phillip and Macquarie Streets that border the protest area may be affected.

A police operation will also be launched to ensure that the protests are lawful and minimise disruptiveness, Operation Commander Superintendent David Donohue said.

"Police will be focused on ensuring protesters abide by the law while maintaining the safety of participants, local residents and the wider community in the CBD," he said.

"We will not tolerate any criminal, anti-social or dangerous behaviour; if you choose to do the wrong thing you’ll be removed and dealt with accordingly.

"The same will apply for anyone who attempts to cause disharmony or incite conflict with those who may hold opposing views.

"Members of the public can be assured we will respond swiftly to violent or disruptive behaviour, or any action that poses a threat to the safety of other protesters or the general community.
