If you want to cut back, maybe take a leaf from my book..

Tent
couple of sleeping bags
two camping chairs
2 burner cooker + gas + couple of forks + 2 pans + kettle.
1 esky
bag of clothes
toolbox with tools/spares etc.
I'm not equipped for serious outback touring, but the above did us fine for 4 days worth of camping.
If you want to cut back, look at each and every item you pack, and really criticise it's worth. do you really need two toilets? two cookers? two tarps?
