The Adelaide University O-Week runs from Monday to Thursday in the week before lectures begin. During O-Week sporting clubs and societies set up a variety of tented areas where clubs display their activities. The Adelaide University Union coordinates a variety of events centering around beer, bands and barbecues on the lawns near the Union complex. A major event for the week is the O-Ball (live entertainment and licensed areas) which takes place in the Cloisters (Union House). The O-Ball attracts many thousands of revellers, not all of whom are Adelaide University students. In recent times Sports and Clubs have sought to distance themselves from the student union and student association controlled activities and have set themselves up on the Maths lawns.
