No real mention of the main enemy, oxygen… A brush fire can deplete the local oxygen levels even if your nice and cool underground.
These are basically small concrete boxes sunk into the ground. They’re only meant to stick out a bushfire for a few hours.
You could probably just keep a few bottles of oxygen or a carbon dioxide scrubber stashed in there, just in case. If you can spend $10,000 on one of these bunkers, spending a few hundred more isn’t going to make a difference.
Anything longer than a few hours would get dicey anyway without room to move around, without room to stash water or food, without a toilet or beds.
They could put in a bunch of high-O2 producing plants like mother-in-law’s tongue and be relatively okay-ish.
