Victorians in flood zones urged to stockpile three days of supplies

We always have at LEAST a week and usually a months food in various forms but the weakness here is how much was frozen: we wound up moving deep frozen expensive meat to friends with power, and ate as much as we could of the less robust food to match the 4-10 window because climbing 9 floors of stairs for 60 year olds is a pain.

In broad sense, we could have survived far longer on the dry goods, given water. We had everything we need, if we can cook. If we lost gas, no amount of 3 days would get us there because we don't keep tinned food consumable from the tin. I guess we could have survived on breakfast cereal and cheese.

I am unsure quite how much tinned food I want to keep to meet a 3 day goal, assuming worst-case no gas. I probably would have moved out.

(which of course depends on being ABLE to move out, but I am on the current evidence in fringeing flood land, not deep flood with no connection. I'm in a city. I just got islanded at points, and lost power)
