According to a police officer on Nine News, Newton was under the influence of alcohol, as he was with his previous battery earlier this month.
Newton, the son of well-known entertainment identities Bert and Patti Newton, was also arrested in Miami earlier this month after allegedly refusing to leave a bar.
Seven Network said the latest charges stem from an incident at the Courtyard Marriott on Miami Beach, where Newton was staying, during the early hours of April 17.
The actor was allegedly involved in an angry confrontation with a man working behind the hotel front counter at 4.51am and threw some papers of the desk.
Newton then punched the member of staff, Seven reported, citing an official police report about the incident.
The worker fell to the floor before being chased around the lobby.
Police arrived at Newton’s hotel room later in the morning and he allegedly resisted arrest.
The incident in the hotel lobby was captured on CCTV where you see Newton lie down on the floor next to the man, seemingly taunting him after the altercation.
