I don't have a chronic illness, and am not Australian. I have friends and acquaintances, however, with CFS, Lupus, and Fibro though.
Probably the one time I remember having "no spoons" for a solid month was when kid #2 was 15 months old, and I got bronchitis. I would wake up, take a shower, eat breakfast, and fall asleep on the couch while sitting up. I am so lucky to have a husband who was able to juggle his job, all of the cooking, chores, and childcare for that month. Even when I was able to get back to work, it took all of my energy.
No spoons meals:
string cheese and dried fruit or apples
Nuts and fruit
Smoothies (frozen fruit, ice, water, protein powder)
Yogurt
raw veggies and store bought hummus
frozen pizza
Some low-spoon meals:
quesadillas or grilled cheese (these require a spoon)
thai chicken curry (rice in rice cooker, can of coconut milk, can of chicken, mixed frozen veg)
canned or boxed soup
plain pasta with butter and parmesan
scrambled eggs on tortillas
bagel with cream cheese
I try to eat veg with every meal, so there are always frozen veggies in my freezer. Plain or mixed. Microwave or roast.
