Alleged far-right sympathiser Max Towns was charged in April after an altercation with NewsCorp Australia photographer Dylan Robinson in Cronulla.
NSW Police allege Mr Robinson's camera equipment was knocked to the ground and his shirt was torn.
Mr Towns, 19, on Thursday had his first mention at Sutherland Local Court where his lawyer entered pleas of not guilty to the charges of intimidation and common assault.
Detectives say Mr Towns first made intimidatory comments toward NewsCorp journalist Eliza Barr and then assaulted Mr Robinson when he tried to intervene.

The scuffle followed a press conference during which Senator Anning announced his Conservative National Party candidate for the prime minister's seat of Cook and part of his NSW ticket for the Senate.
Senator Anning was on the opposite side of the park at the time and said he didn't see the incident or know if Towns was a supporter.
The Queensland politician - who's called for a ban on all Muslim immigration - said he didn't advocate violence.
A police bail document filed in court states Towns is an "associate" of a far-right political group and his alleged actions in late April were unprovoked.
His bail conditions stipulate the 19-year-old can't contact Ms Barr or Mr Robinson, can't attend political assemblies, protests or press conferences, and must not enter the Sutherland Shire except to attend court.
His matter is due back in the same court on June 27.
Mr Towns is not required to attend.
