Police praised the behaviour of young music lovers at the FOMO Festival in Adelaide.
About 10,000 people flocked to Elder Park on the banks of the River Torrens for the second running of the festival, set on a single stage.
Many of the mostly teenage and early-20s crowd were eager to see headline act, American rapper, singer and songwriter Nicki Minaj.
The 10-time Grammy-award nominee performed hits including hits Chun-Li and Barbie Dreams, from her latest album Queen.
Earlier, police seized a small quantity of drugs from an Adelaide hotel room.
It is believed they were bound for the festival.
Police arrested two people after allegedly locating 26 ecstasy pills, deal bags of cannabis and a small amount of cocaine.
A Blakeview woman, 19, and a 17-year old Pooraka youth were charged with drug trafficking.
