Police have swooped on the first night of schoolies celebrations on the Gold Coast, arresting 25 people mostly for being drunk and causing public nuisance.
Schoolies officially kicked off last night as thousands of year 12 leavers descended on Surfers Paradise, with between 25,000 and 35,000 arrivals expected over the next week.
Police, including sniffer dogs, have been gearing up ahead of the event after a number of violent incidents in past years.
The state's heavily-armed Special Emergency Response Team has also been placed on standby.
Queensland police said they arrested 10 male schoolies overnight for 15 offences, with most of them "for being drunk and public nuisance".
Police arrested 16 non-schoolies, commonly referred to as "toolies", on 18 charges, mainly for public nuisance and other good order offences.
Police also issued 15 toolies with liquor infringement notices.
"Generally police were pleased with the behaviour of schoolies, with only a small number of the large crowd coming to the attention of police," authorities said.
On Friday, Immigration Minister Peter Dutton warned those going to schoolies to stay alert in the wake of the terror attacks in Paris.
He urged parents to sit down with their teenage children in the lead-up to the celebrations.
"Make sure that your kids have the appropriate information and are as prepared for any incident when they're going to schoolies as is humanly possible," he said.
While police were pleased with the behaviour of those on the Gold Coast, violence marred the first day of festivities in South Australia after a wild brawl erupted south of Adelaide.
