Acting Inspector Mahony said police officers involved were used as “human punching bags” when they tried to break up the brawl.
Police had been called to the family-friendly park at about 3.30pm on last year’s Australia Day, when small fights broke out among a large group of teenagers who had been drinking.
The teenagers abused, attacked and threw rubbish including bottles at the officers as they tried to restrain them. It was a quiet day at Moffat Beach on Tuesday as police deterred partygoers from celebrating Australia Day at the beach.
Three police officers were injured in the brawl, with one taken to hospital.
