We always have other dried fruits:
sultanas
dates
apricots
Plus 4 types of flour (normal and wholemeal, both plain and self raising - which you call All Purpose). I've never kept flour anywhere but the cupboard - perhaps I've been lucky but these are also a pretty high use item in our kitchen.
Minced beef (ground beef) is also a freezer must - easy base for quick meals, whether it is tacos/burritos/bolognese/meat patties on the BBQ.
mustard - I much prefer hot english. In any case, there are about 4 mustards we use semi-regularly.
potatoes - easy base for many things and don't go off very quickly - there are *always* potatoes in our cupboard.
edit - and of course I wouldn't be an aussie if there was not always a jar of vegemite in the cupboard - not really a cooking thing as such, but definitely a kitchen essential
Things on her list I rarely have:
maple syrup - more likely to have golden syrup which is actually made from sugar - good ingredient for making cookies etc.
bread crumbs - you should make them when you want to use them - soooo much better than store bought...
