Open Question: Camping in Australia for New Years Eve?

My friends and i are looking to go camping in south australia for new years eve this year (yes i know, we're planning early!). It will hopefully be a relatively big group of us anywhere from 10-15 or so 20 year olds. We'd probably be looking at somewhere down yorke peninsula, staying for about 5 days. Any ideas of what we will need to organise for this to happen? We've all been camping with school before, and we know the basics, tents etc, but is there anything specific we need for camping in south aust for a relatively large group?
Thanks :)
