Gypsy I also heard a lot of negativities. There were over 3000 people camped there with facilities for far less than that. It was hot, it was dusty, there were flies, it was crowded, no shade for campers and tents. Blah, blah, blah, blah.
For me however, that's simply Australian. I do believe that the facilities are inadequate but for a once a year festival and not much other use for the grounds it isn't really that bad. I didn't camp but those I know did, had a great time. I went both days and thoroughly enjoyed it. I learnt a lot as well and that is what it is all about.
A guy I know went up in a helicopter and tok some photos and they should go up later in the week. They will give you some idea of how big it has gotten.
