Is anyone doing special teams? They're so much fun (especially Activities *cough*)!
Everyone should come to camp also, it's a blast. VCESS will basically be the best two weeks of your life.
Also if you'd like you can run workshops as well. There are four one hour slots for workshops across the program. Some of the ones last year were gender studies of Disney films, Magic the Gathering tutorials, juggling practice, dance classes, volleyball, and so on. I ran two creative writing classes and two human rights classes which were both really fun to do. So if there's something you're really interested in or passionate about or good at make sure to consider turning it into a workshop**!
Another thing - get involved with helping out for the extra-curricular stuff. Activities are always looking for people to assist with barbecuing and hosting bases for the scav hunt and so on. VCESS is really one of those things where the more you put in, the more you get out.
**Not including workshops on being awesome at VCE internet forums.
