Schoolies not 'toolies' will be welcomed on the Fleurieu Peninsula this weekend for the after-school party of a lifetime for the class of 2012.
The warning against older gatecrashers, dubbed 'toolies', spoiling the good time for young school leavers came from the region's top cop at media conference in Adelaide.
"Our experience last year was that the schoolies were not the troublemakers but we have the numbers to deal with whatever happens," said John Bruhn, Superintendent of the Hills and Fleurieu region.
Superintendent Bruhn said around 130 police officers would be tasked to the Victor Harbor area – a number similar to last year.
"Non-school leavers are always over-represented in arrests, reports and expiation notices. Last year they weren't as prevalent so we're hoping they've got the message."
Paramedics are preparing to treat more than 100 people each night throughout the festivities.
SA Ambulance Service will station a command centre at Warland Reserve, opposite the main festival area and roster on three extra night crews.
"As with previous years, we've put on extra resources to cope with demand," said SA Ambulance operations manager Anthony Pryzibilla.
"Enjoy yourselves but know your limits and if you do get into trouble, don't hesitate to call triple-0."
Patients suffering intoxication, pre-existing medical conditions and minor traumas were the most common in previous years, he said.
Brianna Elliott, Josh Baldwin and Sarah Baldwin will be among the 600-strong contingent of Green Team volunteers who will swamp the schoolies camp by Thursday.
The team will provide everything from transport escorts, setting up tents, bus chaperones and friendship.
"Safe partying is very important," said Sarah.
"We like to serve young people, to kind of look out for them and make sure they have a fun and safe time," said Brianna.
Schoolies Festival officially kicks off on Friday.
