This was our setup for Bathurst. You have to fit it all on an 8x8m plot.
That tarp was a good $2 investment. It absolutely bucketed down that year (2011) so the three of us were huddled under that shelter whilst it absolutely bucketed down.
Those round BBQ's don't pack down too well, so unless you have heaps of room to transport them, I wouldn't recommend using them. Our eskies were inside the front of the tent to keep them out of the sun. (When it was sunny!)
This year, we'll be glamping with taking a mate's camper trailer, so we'll be able to fit a lot of useless gear in there!
For power, I've got one of these:

Picked it up for $18. Should get about 3 phone charges out of it so hopefully that might last the trip. Also planning on taking my old Nokia N95 that lasts a week for general use. Will swap to my smartphone when I need internet to talk to the family back home at night.
