A 19-year-old has been charged with assault and intimidation after allegedly lashing out at a female journalist and a photographer following a Fraser Anning press conference in Sydney.

The Randwick teen, Max Towns, allegedly made intimidating comments to local journalist Eliza Barr after she asked probing questions of Senator Anning in a park in Cronulla.

When her photographer colleague Dylan Robinson attempted to intervene, Mr Towns allegedly assaulted him, knocking his camera to the ground and ripping his shirt.

Mr Towns grinned for cameras as he was questioned by police.

He was arrested and taken to Sutherland Police Station.

He was granted strict conditional bail and is due to appear in court on May 16.

The press conference was held at Dunningham Park because of its connection to the Cronulla riots.

"As you know, this area is the Prime Minister's seat, and there's been all sorts of problems here with the Muslim immigrants who have come in here and attacked people right here where we're standing now," Senator Anning said.

During the press conference Barr was heckled for asking the senator for proof of Muslim violence in the area.

As a local crime reporter in the Cronulla area, she said she had seen zero evidence of any hate crime committed locally by Muslims.

The 2005 Cronulla riots were a series of racially-motivated attacks by a mob of around 5000 mostly white people against non-white beachgoers.

Senator Anning was in Cronulla to promote his candidate Peter Kelly, one of dozens of candidates running as part of his newly formed Conservative National Party.

Already one of his candidates, Bendigo's Julie Hoskin, has been ruled ineligible because of bankruptcy.

"She's a good girl," Senator Anning said of the 54-year-old.

"She was illegally bankrupted. She declared that on the form."

Senator Anning said he vetted 300 candidates for his party over 10 days.

"In every election you've got somebody who's got something in the closet," he said.

"I think most of them are decent people. We might find that there's an axe murderer."

Prime Minister Scott Morrison told reporters the attack was "absolutely appalling".

"That type of behaviour has no place in Australia, that type of violence that we've seen today," he said.

"People should be able to go to work, whether you're a photographer or anyone else, and not be subjected to that sort of violence."
