Something mmm...shiny should view!
Just thinking about this, it is good prepping practice to have a stack of cash on hand anyway, at least 10k imo (or whatever you can safely manage), probably better in lower denomination notes - 5’s 10s and 20s.
It is even better to have this now, because your cash is most likely uncontaminated with coronavirus.
This will change in the event of widespread disease. The change you receive may be contaminated.
While in Asia, use of hand sanitiser after handling paper money is an ingrained practice for a very long time, this will be a new thing for Australia.
You can mitigate that to an extent by having a good supply of low denomination notes.
This also means you avoid the herd panic withdrawal, which in the stacking community has been noted in several countries in crisis.
Who really wants to be in that situation? It is more fundamental than toilet paper.
