Queensland police are talking to the organiser of an open party advertised on Facebook that spiralled out of control when up to 1000 people, including underage teens, turned up.
An ambulance spokesman says five people, including an 18-year-old, were treated for alcohol-related injuries during the party at Tamborine Memorial Hall at Mount Tamborine on the Gold Coast on Saturday night.
Two of those treated were aged 14, the Nine Network reports.
Police said they were called to the hall about 7pm (AEST) and arrived 45 minutes later to find a "disorderly" party where fights were breaking out and security were struggling to control the crowd.
They said it was apparent that large sections of the crowd were consuming alcohol and the mood at times was described as "very aggressive".
The party, dubbed Yo-Yo's Round II, was advertised on a Facebook page promoting open events in southeast Queensland.
Footage taken at the party and posted to the page shows teenage girls dancing on a stage in their underwear as hundreds of other young revellers pack a crowded room around them.
Party host Yohans "Yo-Yo" Schol said he was an experienced organiser and might hold a "round three", having held a similar party just two weeks ago.
"As you can see we have a big clean-up, but hey, I did my job - everyone had fun," he told Nine News.
Police say they are talking to Mr Schol as part of follow-up investigations.
Officers and the dog squad were called in to break up the party on Saturday night.
But due to the party's remote location, revellers remained in a fenced off area until buses could come and collect them at 11.30pm (AEST).
The party was not registered with police.
