A 19-year-old is accused of striking a photographer and ripping his t-shirt on the sidelines of a Fraser Anning press conference in Sydney's south.
Senator Anning was in Cronulla on Friday to announce the Conservative National Party candidate for the prime minister's seat of Cook and part of his NSW ticket for the Senate.
During the press conference, the 69-year-old reiterated his call for a ban on "bringing any more Muslims or Sudanese into the country".
He was pressed by journalists over his claims that locals were being "bashed and attacked" by immigrants.
After the event, a 19-year-old man allegedly levelled sexist and abusive comments at female journalist Eliza Barr.
News Corp Australia photographer Dylan Robinson followed him and attempted to take his photo before the young man pushed the camera away and tried to hit the photographer in the face several times.
Senator Anning was on the opposite side of the park and said he did not see the incident.
Officers arrested the 19-year-old who was later charged with common assault, intimidation and behaving in an offensive manner.
He was released on bail to appear at Sutherland Local Court on May 16.
Barr told Sky News on Friday night that it was a "very distressing" day and the mood at the press conference had become "volatile" after Senator Anning was pressed on his immigration policies.
Robinson took to Twitter on Friday evening to say that journalists and photographers shouldn't be subject to verbal or physical abuse for doing their job.
"I hope in future people will learn to express opinion in an intelligent and constructive way, rather than derogatory comment and physical abuse," he said.
