Founder of the Australian Arabic Council Joseph Wakim says tensions arising from the two year insurrection in Syria are being played out in Australia among some Muslim communities.
According to Mr Wakim it is only a "very small minority of people doing a very small minority of acts".
"It's something that hasn't happened before and it only takes a couple of incidents to create that sense of angst and anxiety amongst the community," he said.More stories from Today Tonight
"Some of them decided to take the law into their own hands as if there is no frontier, no boundary between the war in Syria and the war in Australia."
31-year-old Omar Ammouch was charged with common assault today after punching Jamal Daoud last week in front of Today Tonight's cameras.
Mr Ammouch was accused by Mr Daoud of inflaming sectarian tensions in Australia, stemming from the Syrian war.
Viewer Zacharia Taha also sent in his own CCTV footage of another violent act committed on Anzac Day this year.
Mr Taha and his family lived next door to Belal Khazaal, who was convicted of terrorism offences relating to the online publication of a so-called terrorism manual in 2008.
Mr Khazaal was freed on appeal, but the High Court recently overturned his appeal and he's back behind bars.
According to Mr Taha the trouble began when Mr Khazaal accused him of putting up cameras and working with ASIO to spy on him.
Mr Taha claims Mr Ammouch and his friends are followers of Mr Khazaal and now they're targeting him and his family.
The CCTV footage showed a gang throwing a liquid and numerous projectiles at houses and people on the street that Mr Taha lived.
At around 11:30pm, on the day in question, after more than three hours of antagonising the family, Mr Taha claims he was bashed by the gang.
At least a dozen officers attended the assault but no one has been charged since the event.
"This is Australia, these things shouldn't be happening in the streets and suburbs of Sydney," Mr Taha said.
