These are open sessions that anyone can register for. I'm not sure if the company you work for would pay to have RIM come in and put of a course for you and your co-workers. It's not cheap but you benefit from it, a friend of mine just had their courses this week and they learned a bit. And most RIM trainers try not to just read off the slides either, they try to keep you interested and awake
It does suck that they're not putting off an open session in Australia though. I'm not sure why, but I would think they have some reason. You could always email them and ask why or try to get a quote to have RIM come to you.
