Group multi-days and learning bushwalk skills

Hi all
I've enjoyed doing a few multiday tramps on trails and would now to do this more often (instead of once every 9mths!) and with others.
I also want to start developing off-track skills - orientation, rock scrambling etc. Australia being a new-ish country to me makes me a bit more cautious about trying to figuring it out on my own.
I'll pay to do a course or join a club but haven't found any suitable - courses tend to take people on established multi-day tracks which im happy doing on my own and clubs either only do day walks or require you to already have all the skills needed - where do people learn them?!
If anyone knows of any groups, courses or trip organisers in or around Sydney, i'd be great to hear of them.
Thanks in advance.
