So, the Who is easy - just post in this thread!
The Where - post a suggestion.
The When - we'll wait and see how the who and the where goes, then pick a weekend

Suggestions we've had so far:
- Stockton Beach
(staying overnight in the caravan park, doing some sand dune 4WDing, and some beach fishing)
- Newnes
(bush camping, easy 4WDing)
We have a book with a huge range of campsites (arrived last night) that I will have a flick through and see if there's anything decent within range from Sydney and add to the list of options.
There has also been an offer of a spare seat or two, so if you don't have a 4WD but want to tag along for the weekend, post up and see if you get adopted for the weekend
