things to cook in, including if you have it those funky grate things for toast
kindling and fire starting equipment including paper (have both matches and lighters)

Extra rolls of toilet paper
mossie spray, citronella candles/flares, fly spray (for in the tent and the "windows" - spray before dusk, close up the tent)

food:
work out a menu plan if possible,
toast/bacon/eggs/beans for breakfast - you can also make damper instead of toast
lunches can be light and you won't need to cook
dinner - make sure it is something that you can cook in the dark if you need to

also have something "spare" that you don't need to cook in case of rain and the fire going out
