Police detectives were brought in to break up a number of altercations at the Stereosonic dance event at Sydney's Olympic Park on Saturday (November 26), and ended up charging offenders with drug and violence offences.
It is believed that riot police were called when punters threw bottles at police who were trying to break up fights.
More than 60,000 music fans attended the festival, but about 100 people were refused entry or kicked out for being too drunk or aggressive.
A police representative told The ABC that dozens of festival goers were charged with drug offences. Three people were arrested for assaulting police officers and four were detained for resisting arrest.
Artists performing at this year's Stereosonic included LMFAO, Acid Jack, Andy C, Afrojack, Annie Mac, Armin Van Buuren, Bag Raiders, Claude Vonstroke, Bloody Beetroots and Empire of the Sun.
As well as Sydney, the music event also took place in Perth, with events to follow next weekend in Adelaide, Brisbane and Melbourne.
Earlier this year, paramedics were called to Australia's Big Day Out music festival in Melbourne to treat 1,400 people for dehydration. However, the festival fans' behaviour was commended by police.
