If the grocery stores run out of some of the foods you want, you could always stock up on hamburgers, fish sandwiches and fries from your local McDonalds if you have them in Australia.
We have MacDonalds, Kentucky Fried Chicken (KFC) and Hungry Jacks (Burger King) in Australia.
I can't eat fast food due to the wheat, gluten and preservatives in it.
I became intolerant and allergic to numerous foods after being put on anti-biotics for a month. They didn't fix the problem and simply made me unable to eat most prepared foods.

Do you live in the middle of nowhere??
Yes and no, about 100km south of the capital city but 15km south of a country city. Total population about 40,000 people, about half are over 50 years old and at high risk of dying if the corona virus sets up shop here. The medical facilities aren't that good here
And the place is crawling with inbred hill billy 4wd owners that think it's fine to park oversized 4wds and caravans on footpaths so pedestrians have to walk on major roads to get past them. It's the younger population (20-40 yo) that are the inbred hill billies. The older people and kids/ teenagers here are all nice and polite.

I essentially do, lol. I live on 25 acres of wooded property, and it takes me 15 minutes to drive to town on a gravel road.
It takes me about 20 minutes to get to town on a sealed road. Way too many traffic lights to deal with

For anyone wanting to freeze dairy products, it's fine and will last for years if kept frozen.
If you have an auto defrost fridge/ freezer, that can cause food to spoil after a few weeks. The best freezer for long term storage is a chest freezer that does not have an auto defrost cycle.
