i'm not in the area i'm in melbourne but good on ya for posting it, my FIRST job was in gosford and i lived in a garage behind the wamberal surf club LOL and drove a HR holden, ahhh those were the days...............
SO, anyone in the area get along to these meetups, they are GOLD and i go to as many as i possibly can much to the disapointment of other members
you don't need "a few" , you just need 1 other and i can tell you form experience that is MORE then enough.
obviously in melbouren or other capital cities there are more domainers, i go met domainers 1 on 1 regularily and the knowledge we share is just crazy in such a short period of time.
SO, create your event and people will come,, post about it afterwards and it will grow.
best wishes
