Have spoken to some mates at Uni that have hired out rooms before, and they reckon that hiring out a room is much cheaper than a lecture hall...

Link above displays the cost of hiring rooms, halls and lecture theatres to Curtin affliated and non affliated members.
If Perth members are keen, we could look into every chipping in say $5 bucks each to hire a room out for a few hours or a day for this meet.
Being a 4th year student, I'll see if I can use that as leverage to lower prices (pull a few strings with lecturers I get along with) in order to get a cheaper rate if you all are interested...
Give us some feedback guys?
