Contestants kicked up their heels and partied country style at Cromwell College on Thursday night.
Vegemite was one of the many foods offered during the evening, however many tried it with hesitation.
Contestants and volunteers danced to the Nutbush, painted each others faces in green and gold and blew bubbles throughout the room.
A conga line was enthusiastically created on several occasions and contestants even boogied to the Macarena.
Competitors said it was a great way to blow off steam after a stressful week of competing in the IOI.
