its a good idea, but it would have to be held some where neutral, like say Canberra. and somewhere free. as the organization and costs are painful.

are organizing a nation meet. there not sure where yet tho. more than likely Sydney or Wollongong.

having said that there are always cruises being organized. there was one just the other night in Sydney, organized by SOO081.
i dare say there'll be another soon.
