Challenge - National gathering

O/K so we dropped the ball this year. 2005 was great but wet.
A varst base of knowledge within this community (EO)
Challenge, site and date for 2007 national gathering.
Criteria. (add or delete as you see fit)
1. Not an established caravan park ect. Most of us I think can survive three or four days without amenities.
2. Must be able to have camp fire.
3. Access for those who are towing.
4. Room was large numbers of campers.
5. To reduce travel for all as much as possible, should be outback QLD, SA, NT or NSW. Sorry WA & TAS don't mean to be rude but most seem to be in those four states.
6. Date suitable for those with children.
7. Things to do other than drink & BS around camp fire.
8. Participants must be flexible and willing to compromise.

What do you think, can we do this or is it just too hard.
My knowledge of suitable places is non existant.
I was thinking private property somewhere.
