there's plenty of action here in oz once you get in on it. we don't advertise much, but we're beginning to grow so that might improve. there's an annual assembly, groves and seed-groups, and serpentstar is the newsletter downunder. i've just handed over the editorship to kim morley, and you can reach her to subscribe at firstname.lastname@example.org
(it's free on-line or you pay for postage etc - not much). Melbourne grove is very active - contact details at http://druidnetwork.org/node/1001598
(i googled melbourne grove elkie white). elkie is very approachable and is a contact for it. the not quite annual assemblies are wonderful if you can get to them - druids from kingaroy to perth gather for two days or more of deeply magical ceremony (you have to be in it to know how deep and powerful it feels), sharing and talking, partying, and believe me, thrilling eisteddfod. kids get worked in happily too. some assembly hosts even let you take the dog as long as it's controlled. the next one is in 2011 at cooringal grove in port lincoln, sth oz. details will appear in serpentstar, so it's worth subscribing. it's a good little newsletter, too, and welcomes contributions.
i agree it would be good to also get something going that included all druids. and yeah, one of the big things is the need to re-craft our ceremonies for our local conditions at home, and also for general reference when we all get together from far-flung corners of the continent for ceremonies. but the emphasis is often much more on rites of passage, initiations, namings, cronings, etc, so the importance of the seasonal stuff is tending to diminish a bit at those shows.
hope to meet up with you at the next assembly.
