Hi!
I'm also in Oz - but I wouldn't have any idea about anything much to do with Aussie as I've really only just started freeriding recently - I've skied my whole life, but have been overseas, and started when I was working in the french alps last season.
I was really impressed by the number of rails at the buller park when I went there with my family this year, but surprised to see so few skiers - it was weird, I went there to teach my little brother how to slide, and got ambushed by curious boarders who hadn't seen skiers on the rails before (so he got stage fright and we left). The few skiers that I did see on the pipe, though, were really good - people must be learning somewhere - where are the intermediates?
