Liborio Di Vita, 35, appeared in Southport Magistrates Court on Wednesday charged with assault occasioning bodily harm following the May 21 incident at North Burleigh beach.
Police say Mr Di Vita, who is believed to be a member of the Black Uhlans outlaw motorcycle gang, assaulted lifeguard Phil Gregory after he told Mr Di Vita's girlfriend not to walk a dog through a red and yellow flagged patrol area.
It's alleged Mr Di Vita confronted Mr Gregory shortly after being informed by his upset girlfriend of the incident, shouting at him before slapping him to the ground.
Police say he then punched Mr Gregory as he lay on the ground and kicked sand in his face before leaving the scene and heading to a gym.
Mr Gregory was left with facial injuries including a cut around his left eye.
In granting bail, Magistrate Brian Kilmartin set down the conditions that Mr Di Vita must report daily to police and is banned from Burleigh beaches.
Calling the attack "cowardly", Mr Kilmartin also fined Mr Di Vita $200 after he failed to appear for a scheduled mention of the case on Tuesday.
Mr Di Vita claimed he had a stomach virus that prevented him attending court but had handed himself in to police after an arrest warrant was issued.
Outside the court, Mr Di Vita's lawyer said his client didn't accept the allegations against him.
The case resumes on July 18.
