It’s easy Angela.
All you need to do is find a thick-skinned organiser who has a few free weeks to research venues, create publicity, sell tickets, cop all the abuse, and make things happen on the day.
Then you need to find about 50 members of the community who won’t complain that the tickets are too expensive, the event is too safe or too public, the entertainment is too little or too much, or who consider it is only suitable for crossdressers/transexuals/gays…take your pick!
After that it is just a piece of cake!
Good luck…but seriously the first thing I think you need to focus on in QLD is to organise simpler social events. In NSW this helped us develop a base of people who would attend functions like a ball, and provides a way of selling tickets to them.
