Police reported no major incidents and said they were generally happy with the behaviour of revellers.
Many family groups enjoyed early celebrations at the beachfront carnival and market and also the performance of the Samba Blisstas drum group. Police either confiscated alcohol being carried in alcohol-free zones or ordered revellers carrying opened bottles and cans to tip out the contents.
Tweed-Byron Police duty officer Inspector Darren Steel said the Byron Bay crowd was slightly down on what was anticipated.
Inspector Steel said seven people were charged on assault-related matters, 21 people were detected carrying alcohol in alcohol-free zones, four people were detected with drugs, 16 people were issued with court attendance notices for offensive language and two people were charged with failing to leave licensed premises.
He said one reveller was charged with unlawful possession of fireworks.
