One of the youtubers I follow is Beau of The Fifth Column. Not his real name, TFC is his news outlet. Former security contractor turned conflict journalist, and very "Florida man" He's political, but really digs into nuance, shares ideas rather than pushing an opinion. Anyway, he's full black-flag anarchist, so community is one of his big focuses. Local support for local crisis, helping your neighbors etc.
If this thing goes really bad, I doubt we will loose the basic services like power and water (though there may be limiting), the fatality numbers have to get pretty extreme before stuff like that happens (double digit fatality rates, and high infection rate) but other services, schools, hospitals, and general services like that will get stressed. So I think this is where knowing your neighbors and being in that bushwalking mindset can really help. Even if you don't think you have that many useful skills, consider what you do on a group walk. Someone should be asking about rest breaks, does anyone have any hotspots, how's that pack feeling, did you drop this... Those sorts of little things can help the people beside you. Maybe someone in your very close area cannot get to the shops easily without strapping a bunch of kids into a car, being able to get a few things for them could be the thing that helps keep them safer. Odds are good that deliveries and such will continue to happen, but not everyone is comfortable with that. Knowing that things are available also keeps people from feeling like they need to hoard.
Cooking, meal planning, and food storage are things that many of us have learned "the hard way" maybe there is a power outage, the bushwalker is likely to have a better idea of not only what and how to keep cooking, but also how to get the maximum efficiency from the fuel they have. Yes, you can boil noodles in a pot directly on the BBQ hotplate, but is that the best way to accomplish that? Maybe you have gasbottle service, do you "need" hot water, or is it possibly a good idea to let the hot water tank go cold, and save that fuel for cooking? Lots of people have at least a little metho in their home for cleaning, but how many know how to make a tuna-can burner?
These are things that to a bushwalker are part of the process, if you took a list of all your resources, and how to stretch them, you would probably come to these same conclusions. What about your neighbors? What do you have that you can pool together to make sure everyone is okay? Maybe your street has limited skillsets that are "useful" but I bet those folks are telecommuting and might need help with some other things. Maybe your neighbor is actually a really skilled tradie and can do a lot, but needs tasks and a planner? Many people have just never planned every meal and snack for a week, let alone for longer, or for a group of people. But maybe one of them has.
I'm guessing that many of the folks on this site have some reasonable first aid training, and decent kits. More than that, I bet many have handled wound care for a few days on their own, maybe longer. That's scary to a lot of people. Wounds need doctors, and what happens if that little cut can't be seen by a doctor? Does that person really need to risk going in for a tetanus shot if the doctors office is full of people with coughs and sneezes? Or can you tell if an infection is starting to go bad, so that you can help that person get to help rather than letting the fear hold them back? I bet many people here could. Or maybe its as simple as knowing who down your street has more knowledge about a thing and helping connect the person who can help with the person who needs it?
This is going to get worse before it gets better, and we will decide what the new normal looks like afterwards. Lets make it a normal that we aspire to, not the one based on fear. The response to the fires was amazing, and a lot of us could help while staying safe. We don't get the option this time.
This vid was done just post Hurricane Michael (2018) and he caught the edge of it. Worth a listen I think
